3W? is that all?

Sure, but the second you get dynamic peaks, you're immediately out of any head room. I'd hope they were very efficient

I'm thinkin' about 94dB, so they're fairly efficient and remember this is an office system. I would imagine that ear-searing volume isn't in the playbook. Plus, knowing B's style I don't think that he's bumpin' any Chemical Brothers or bass-heavy tracks...

During normal listening, I use 0.2 watts per channel, to have decent sound. That with my 87 db/m power hungry thiels...

3 watts of pure class A is enough for efficient speakers.

Bernd the office system looks amazing. I just read an excellent review on the Shangling. I find myself becoming more interested in a single driver speakers and with tubes I bet the sound is very intimate. Well done. Oh and the Princess' are also lovely.

My 10w amp clips pretty fast. Granted, my speakers are very inefficient. I won't be taking such a route any time soon. Not that i'm not happy with my system, it's nice to know the amp won't start clipping the second you crank it a bit. 94dB, that would be around 10 more than mine. Should be all right then I guess

I'm sorry, but I find that hard to believe Basite. You must be listening at whisper quiet levels if you are just using 0.2 of a watt per channel. Your speaker specs are; 87db at 1watt/1mtr, and mfrs generally tend to overstate efficiency. Perhaps you should check your power metres. I can assure you that you are using more than 0.2 of a watt for an 87db speaker at reasonable listening levels. My speakers are much more efficient than yours, and require considerably more amplifier power than you suggest. For 3watts to be sufficient power for a speaker, that speaker would have to be VERY efficient, such as the fostex/lowther type driver Bernd has in his office system, on the order of 95db @8ohms or more. Even though 3 watts will run a speaker system of average efficiency, say 90db @4ohms, much more power will be required to accurately reproduce a recording with wide dynamic range without distortion or colouration.

Whattup Shaggy,

Lemme go on record as saying that I'm very much looking forward to your system pics. While trolling I caught your little "my speaks are on the left..." dealio and now I'm intrigued.

On topic, I swear to god I'm thinking about ordering one of these Fostex systems...except that I've run out of rooms. Great stuff Bernd.

Peace

Thanks bobs., just go for it. And I would also love to see shaggys system pics.
But back on course and me being me I had to mess around a wee bit with the set up. I moved the Horns slightly and it improved the bass response noticeable. I then went on a tube hunt. Not much info on the stock chinese tubes, but a dutch friend of mine is some sort of a tube wizzard and he helped me get these.
I replaced the chinese 6N3 with NOS GE 5670
and the chinese 6P1 with NOS Original 60s Svetlana 6P1P
From the moment I switched the little beastie on the transformation was indeed, the so often used term day and night springs to mind, very noticeable. Detail, tone, timbre and dynamics had all improved greatly. It just shows how poor those chinese copied tubes are. This little set up has to be one of the best bargains around, and I reckon if you don't need very deep bass and play within the systems capabilities it will make you smile disc after disc. And that is worth a lot in my book.
For info purpose. The CD drive is a Philips sorced one and plays great. Not one rejected disc as of yet.

Peace

BS, I'm giving serious consideration to building a Fostex system. I would need to keep the cost under $500 but that's possible with the an FF165K driver and BK-16 cabinet kit, both of which and be ordered from Madison. The good news is not crossover to build or components to buy.

By the way, I'm a fan of Scotish nationalism, my ancestory being 1/2 Scotish. Long live devolution! Independance? Well, we'll see.

Maybe something like these proper speakers decorated in tartan.....http://www.audioasylum.com/forums/hu...13/131598.html

yes sometimes they overstate their efficiency, exept for with thiel, where they rather understate it...
and yes, I listen at 0.2 watts most of the times, not that I don't go louder (especially during the day, when a little louder can be pleasant (say 1 to 4 watts or so...)). But during the evening and at night (when I listen the most), the amp often doesn't put out more than 0.2 watts averaged. It's 'loud' enough for me...

and Bernd's running +- 100db/w/m horns, even with a 3 watt amp, it will go loud enough for in an office system. Considering he does not really listen to heavy electronical music (with lots of deep, demanding bass), or classical, with extreme dynamic range, and also demanding bass, I think it's pretty safe to say he can absolutely enjoy music with his system without it sounding disorted.

Keep them spinning,
Bert.
