    weigh-in
    Lots of interest in the subject. I am happy with the relatively cheap PS Audio aftermarket job on my CD player ( 49.00 us). Slight improvement in sound separation and quietness. What I should have done is just to buy the 13/3 wire and get some hospital grade connectors and make my own as sugggested here.

    The forces of suppy,demand and criticism (technical sobriety checks) should hopefully keep the cost of this tweak under control a little more than the speaker wire explosion. It looks like a DIY project for the average power cord be cone without soldering for about 30.00 using very good wire and hospital grade connectors. Performance may be as good as the very expensive cables and the hobbyst can make them, put them in and not fret about slight improvements from more expensive units ( like I did on speaker cable).

    Power source
    I have suspected for some time that I may need to finance expensive power cords, so fairly soon I will give them an honest audition.

    Does anyone have experience or an opinion (yep, here I go aking for it, think I'd know better by now) about the relative merits of spending money for power cords (hundreds of $$ is easy) vs spending money for a dedicated run from the main panel breaker to the system. 'Course we'd go with the hospital outlets and good distribution box. Seems the two costs could be comparable. Eventually, I plan on doing both, but I am one of those unlucky folks that must dribble out my limited finances in a controlled fashion.

    And a related question, there is a strong temptation to make my own fancy cords, connectors and wire are pretty easy to aquire but has anyone really listened to the difference on a first class system (No mine isn't truly first class but it makes a solid second class, and I hope to continously improve it)

    As I get more experience in this hobby, I'm kind of determined to not repeat expenses and upgrades in a small step wise fashion like I did early on when I couldn't believe that good sound could cost that much. I could have saved some money by skipping a lot of intermediate steps (not that I wasn't told this) but who can believe this stuff?

    Sounds like you didn't quite get the improvement you were expecting Davie but making your own with decent connectors is a reasonable comprimise. I normally make my own and I use decent connectors and that rubber insulated cable that is used for some power tools and make them as short as possible. Sonic improvements? no, but the rubber cable is more flexible than the PVC stuff and generally nicer to use.

    I can understand the debate with signal cables although I am not going there but with power cables I see it like this; AC mains is fed from a power station at very high voltage. before it gets to you it is transformed down several times then fed to your house at domestic voltage. It is beyond anyones control. Mains voltage is then fed onto the mains transformers of the power supplies of each item of electronic equipment. the voltage is then transformed either up or down depending on whether the equipment is valve or solid state then rectified smoothed, filtered and stored as pure DC. The better the power supply, the purer the DC and more of it. With a good power supply you could flick the switch off and on again and not hear it.

    If you spoke to the designer of a of high quality power supply and suggested that you could improve the performance of that power supply by changing the incoming mains cable expect either myrth or anger. If he agreed, go and find someone who can design proper power supplies.

    If any connection is critical, it's not the AC supply to the power supply but the DC connection between the power supply and the equipment.

    Anybody who thinks he can hear the difference between mains leads really should have gone to more live gigs, then he would sometimes have trouble telling whether the mains lead is plugged in at all. They have probably still got all their dinky cars in their boxes as well

    I will be interested in reading any improvements from a home made power cable. My experience is based on my integrated amp and I hope you try a cable for your amp and report back to us. Are you considering any shield techniques that some power cables employ?
    I also need to ask Chas about the point of concerts compared to what you hear at home. I am also a little curious about dinky cars in their boxes. Odd reference.

    not for the power amp
    I'm not planning on doing anything with the power amp cord because it is still under warranty by some slightly crabby guy up in Minnesota who would have my head for such a thing. I have changed out the plug on my Tuner (MagDYN FT101) top a hospital grade plug and I noticed an improvement. Unfortunately I also buffed up the RCA outputs on the back of the unit at the same time and I suspect the sound improvement came only from the cleaner connecton points, which made me think about cleaning my stuff more regularly.

    I'll tell you the point, my ears are 51 years old. Over the last 35 years or so, I've probably played too loud, too young, too often and been to far too many loud gigs. Still go to about two or three a month. Add to this, the other manly pleasuers like shooting and fishing. Fishing? yep, having to sit over big diesels on my fishing boat for hours on end and don't forget the wife nagging. Now in my opinion, that all adds up to over 35 years of worthwhile use not abuse but all of these things take their toll on your shell likes.

    My passing interest in sound reproduction is to be able to play and get a half way decent sound out of my accumulation (the word collection would give a wrong and probably nerdish impression) of music mostly on LPs and some on CDs.

    The recording quality on quite a few of my records is absolute cr*p but when you get something like Jack Bruce and Ginger Baker (before Eric appeared) with Graham Bond and Dick Heckstall-Smith, you really do want to hear what they were playing. I've got things like unrealeased studio takes from Coleman Hawkins, I want to hear it

    I am fully aware that to get decent results you need decent kit but mine is just bog standard, working man's studio grade stuff and some of that is pretty old now. If I thought I could make it any better by buying £100 worth of cables I would try it but in reality it is only something like yet another grands worth of cartridge that actually works.

    When I look at this site I do often wonder whether people really want to reproduce music accurately to listen to and enjoy or whether they just want to own some sort of expensive train set substitute to impress their friends.

    On a completely different note; Davie, I would say it was probably cleaning the connectors that gave you the improvement. When you make up leads do use decent (industrial quality not exotic) cable and connectors but as I have aid before, I dont believe it will ultimately improve sound but it will provide a more robust and corrosion resistant lead.

    Hi Chas,

    Good to read your post. I am 44 and also like shooting (goes with my job) also go to a couple of gigs a month. Therefore my ears have also been used extensivley. I have however a passion for really good clean reproduced sound and that costs a small fortune. Due to circumstance I had do downgeade a couple of times and also I still enjoyed the gist of the music I did look for more.Isn't it strange that we can listen in the car with all that noise and enjoy a really good track just the same. I guess subconsciously we listen differently how the situation demands it. I think our brain fils in the missing bits if there is too much noise, but at home in a quiet room we listen for different things but with the same enjoyment (for me anyway). I actually dislike going shopping and buying new things for the Rig. And only will do it if I think it is absolutley necessary.

    Hope you all had a good weekend

    Peace

    Hi Bernd

    Like the sound of your job, unless of course, you have to put up with some b*gger shooting back. Yes good weekend thanks, hope yours was too.

    I think you and I pretty much singing from the same hymn sheet as far as music reproduction is concerned.

    In my opinion ther are many variables in sound reproduction and in many cases these do not get fully addressed and statements are made that do not hold water. As a typical example recent post read something like "modern quipment is now so good that we can reproduce the nuances of live music". What live music???????? Unless you go to small venues and listen only to acoustic music (ancient or modern) you are almost invariably listening to reproduced music via a PA system. I went to a Byrd and Tallis concert a year or so ago but it was a big venue (wasn't thinking when I booked the tickets) and the choir was miked so the sound wasn't as good as I'm used to at home. Still enjoyed it though.

    I know that recording quality is quite variable, even on 1 LP there can be tracks that are harsh and others that are fat and wooly so what do we make judgements on.

    I don't believe that there are many people around (and certianly not over the age of about 16) that can hear the things that some of the HI FI reviewers say they can. People are told that X is better than Y and they go and listen but they can't really hear any difference but because the reviewer said it's better they stop trusting their own ears and start listening for things that just aren't there. They are also frightened that the snotty nosed kid of a salesman will think they have got cloth ears so they buy it, take it home and listen intently in the hope that one day they will eventually hear it and it will be like a religeous expreience. These people stopped listening to music years ago, they only ever buy audiophile recordings and just listen to the nuances.

    A lot of the statements made by a well known UK cable guru are questionable to say the least.You know my opinion on what power supplies do by now so I don't want to go over that again but suppose you did want a better that standard mains supply to your equipment, forget the cable guru's way with expensive plugs and sockets, this is the engineers way:

    1. Get a second consumer unit with space for sufficient circiut breakers for all of your components plus a few spares.
    2. Buy a set of breakers to suit the ratings of your equipment or at least the cable used.
    3. Have the second consumer unit connected by the electricity supply supply company directly to the incoming main fuse.
    4. Run seperate cables from each breaker out out to a suitable connector for each item of equipment.

    This way we have got rid all of the interfaces; wall sockets, switches, plugs and fuses and cable connections. Sound far fetched, shouldn't do becuase that is exactly how power is distributed on boats. You couldn't afford to have all of those connectors in a marine environment because of corrosion.

    Now let's sit back and see how long it is before some one tries it.

    Of course, if you wanted to really be a purist you could open up your equipment, dispense with the mains connectors altogether Bypass the equipment power switch and fuses then solder the mains cable straight on the the primary side of the transformer.

    All the best

    Hi Chas,
    Yes good weekend here too. Nobody shoot back (birds and guns-don't like the sound of that) at least until now.
    You described it right with the power issue. I am not that "commited". I do have however a spur only for the Audio Equipment. That will do for me. Hope I am not disqualified for that lack of effort.

    Only those engineers who are unfamiliar with RFI. Such is caused by among other things, the CDP a couple of feet away from the amplification that will happily amplify the "tizzy" brightness imparted. I have two dedicated mains sourcing my main system and find that some aftermarket cords lower the noise level and allow for higher low level resolution.

    YMMV...

    If you have no faith in the designer of your fine equipment being able to suppress RFI, you can buy suppressor chokes that clip around cables for about 2 bucks a time.

    I would have thought the likes of Krell and Levinson would also know about that. Wouldn't you??

    E stat, by that do you mean your CD player a couple of feet away from the amplification?

    If so it is likely to be interferance radiating from the amplifier's mains transformer so put your power amps on the floor, where they belong; dirty filthy things.

    I can't speak for those companies because I don't own their gear. Having spoken to Ole Lund Christensen (formerly) of GamuT and Luke Manley of VTL, however, both acknowledge the value of aftermarket cords. The former provides his equipment without a cord and the latter, cheapo cords so that the user can choose the one that works best in his or her system.

    When someone can analyse by fundamental scientific, physical or electronic theory exactly what a piece of wire can do, irrespective of the materials of construction, that a handful of electronic components can't, then I'll believe it.

    Remember that guitarists, for example can cheaply buy a device (I think it's called a pod)(and have been able to for some time) that can imitate practically any classic combo going then it would also be possible to digitally model the effect of mains cables if there actually was one. But food for thought.

    Yes. It is the component on the bottom shelf. That is true of most systems, no? Do you put yours in another room? And the ICs are shielded likewise for the same reason. I keep them short for other audible reasons.

    Done that too with the monoblocks. Actually, the villain is the digital CD source, not the power amp. The amp happily amplifies all the nasty RFI it encounters either airborne or through the AC line. That's the point!

    Theory works great when you fully understand the problem.

    Ok, EE 101 teaches that wires are quite effective antennae. Better still, listen to a good system using effective RF shielding and hear for yourself so you don't have to rely upon theory to guide your opinion.

    The object is to reduce spurious radio frequency noise generated by digital devices. You cannot eliminate that with EQ or a synthesizer.

    I know that wire and practically all other metallic objects act as antennae and we know we have no control what so ever over the miles on distribution cable from the power station but are you seriously trying to tell me that the only way to get rid of that interferance is by a short piece of exotic wire rather than electronic components and good power supply circiut design.

    Impressive looking kit though E-stat but with your components being that close to your speakers, I may go as far as to diagnose that you could be suffering from a minor case of microphony, particularly if your amps are bottle jobs.

    My kit is all in the same room but the speakers are about twenty feet away from the rest of the kit (good 'eavy speaker cable is used) also my 'equipment rack' is several tons of masonary, a disused chimney breast.

    Increasingly, more companies are putting more effective RF trapping strategies in their products. "Good" power supply design alone does not solve the issue. You cannot get away from the notion, however, that there is an AC cord attached to the components. The filtering goes both ways, too. These cords are specifically designed to prevent "backflow" into the mains as well.

    The photo lacks some perspective as the U-1s are eight feet away from the amps. Most of my listening is done at low levels so I doubt microphony is at fault. How would a power cord minimize it if that were the case?

    Weren't we talking about proximity between the CDP and amplifier? That is one of the problems power cords addresses. A twenty foot run of my speaker cable would cost me another $900.

    RFI is not a new discovery, the text below is a very brief exctract of the list of additional requirements from one of my old specifications for some control equipment:

    • Electrical safety certificate
    • Year 2000 Compliance statement
    • Input/output Verification test results
    • Certification in accordance with CE requirements of immunity to radio frequency and electromagnetic interference.

    The reference to Y2k compliance gives some clue as to the date.

    I would be as bold as to say that the problem of interferance between your CD player is either a defective component or a design fault.

    Ever considered that the physical properties of a power lead could have some small impact upon the the resonance of a chassis.

    If that's the case, then virtually all CD players including some really nice ones like the Burmester 969/970, Blue Note, EMM Labs, all share the same design fault. :)

    Well since the speaker cables are not in the recording chain, it wouldn't matter would it? The better studios (and I) prefer to use better than zip cord.

    There are quite strict regulations for radiation of and susceptability to RF and EM interferance so I'm quite supprised by this.

    Without being there and being able to conduct a few tests I am somewhat in the dark but let's investigate what you say about your CD player apparently sending out large ammounts of either RF or EM interferance. You say it affects your power amps, OK fine. Now does this interferance show up on your phono stage? If the CD player is the rogue component the phono stage would be the item that "should" be most susceptable as it will be amplifying about 0.5mv upto 0.5v. Have you tried these two in close proximity? Have you tried a different power amp? Leads are not the way to cure RF problems I'm quite prepared to believe that there may be some small impact but you are treating the spots rather that the desease.

    You will be able to draw your own conclusions from the result.

    Recording Chain? No. But they would have used speakers for monitoring the recording and if the recording had been EQd to sound OK on equipment that sounded for example, bright, the recording when played back on good neutral equipment would sound dull.

    Please consider that those marvelous analogue recordings of the late fifties through to the early eighties that everybody loves (of course I don't mean all, I mean the good ones) were made using ordinary working man's equipment, no exotic components, no exotic cables and no fancy effects.

    All the best and hoping you cure your problem

    "Strict" is a relative word. Here's a quick test for you: Place any CDP near an AM radio tuned off station and you will HEAR the interference. Even my battery powered portable Sony Walkman that complies with "Part 15 of the FCC Rules" causes this interference. Maybe the manufacturers have to build UK specific units that are more stringent. Dunno.

    Sure. I use a low output moving coil cartridge with a 0.25 output which would make my system more sensitive to such. That's one of the reasons I turn the CDP off ! More specifically, the IEC power cord for the CDP is also shared with the turntable. Their use is thus mutually exclusive.

    Sure. My Threshold Stasis in a different system with a different CDP (Pioneer Elite PD-54) likewise benefits with a lower noise floor using an aftermarket cord. I have two reviewer friends who have run quite a few components through their systems and have found the same result. Harry Pearson uses no fewer than eight Nordost Valhalla cords in his primary system. Slightly more in his killer multi-channel / AV system. This is not an isolated "problem" with my CDP.

    There are a couple of considerations here. Zip cord is insufficient to resolve some of the detail to which I refer. The engineers just EQ the result to whatever they want. The effect is subtle - I'm not suggesting that these are night and day differences, just audible.

    Everything is relative. While I enjoy a number of RCA Living Stereo recordings from the 50s, better exists today. The relevant consideration is that the sins are cumulative. I'm not particularly impressed with the ultimate resolution of most "pro" gear anyway.

    Thanks, but there is no "problem" to cure. Only an issue that is nicely addressed by the cords.

    You might find these comments from GamuT's chief engineer concerning this topic interesting:

    Oh well looks like I'll just have to keep my old Brit kit going, this modern stuff looks far too highly strung for me. I want pleasure not pain.

    Marvellous. I changed the power c(h)ord on my PSL330 to a Wattgate 350 termintaed high current PowerKord and the sound is definitely yet another notch up the sweetness scale. Without a doubt.

    Oh how i *wish* this wasn't the case, for Chas's sake if nothing else... ;)

    Call me back when you have measured it!
    Several posts ago I made this statement "When someone can analyse by fundamental scientific, physical or electronic theory exactly what a piece of wire can do, irrespective of the materials of construction, that a handful of electronic components can't, then I'll believe it".

    So far I've been told things like it reduces noise floor, it adds sweetness, noise from rectifiers goes back throuh the transformer back up the mains lead etc etc.

    What I am saying to you audiophiles is fine, you've told me what you perceive now go and connect up some test equipment and measure it. And don't tell me you able to hear things you can't measure because that's b*ll*cks (Anglo Saxon technical term) You can't hear the output from a MC cartridge untill you have amplified it many times but can measure it's properties easily.

    So far I've yet to see a single performance claim for cables that included a technical specification or a reference to any physical unit and quantity thereof.

    E-Stat, if your cable has reduced the noise floor, measure the improvement. has it gone down from -100dB to -103dB? I really would like someone to measure it and tell me.

    Millions of people believe in life after death and have done for thousands of years. Wonderful thought, I'm sure it gives people a lot of comfort and very good luck to them but no one has ever been able to prove it. So therefore untill someone does, I'll presume this is the only chance I'm going to get and try make the best of it.
