You won't see me reviewing cables much if at all. Largely because they're system dependent so a cable or conditioner may do more or less for me than it would for you. So it's a bit of a pointless exercise. I have Tara Labs Prism 11 IC cables that were well reviewed back in the day. They really don't improve the sound over the cheap cable that came with my CD player. The Cambridge Audio CD 6 may not be the greatest but it was arguably the class leader in its day (or right there). If it is "better" it isn't better enough to pay 60 times the price for it over the $1 variety.

I heard an expensive MIT speaker cables versus cheap runs - the MIT sounded much different - much worse than than the cheap cable - but it did sound different!

MY AN J/Spe is a silver wired version where I had opportunity to directly compare to the lower priced copper version. The Silver version sounded much better in direct comparison especially in the upper mids and treble.

I liked Peter's idea (even if you don't like AN or Peter Q) the notion of wiring the entire audio chain with the same wire structure makes a lot of sense.

Logically - it doesn't make sense to have a system wired with many different cables trying to find some sort of match. In a mix and matched stereo with turntable, transport, DAC, preamp, power amp and loudspeakers - if all were from completely different makers you would have

turntable (internally wired with cable A and possibly the RCA cable to preamp being different - cable B)
Preamp is internally wired with cable C
You buy IC to power amp - Cable D
Power amp is internally wired with a different cable again - Cable E

You buy speaker cables - Cable F
They are connected to different cables in the speakers Cable G.
Transport has different cables again - Cable H
DAC had different cables - Cable I
Then you buy cables from transport to Dac (and the same ones going from DAC to preamp (2 sets of cable J)

That's 10 entirely different wires - theoretically with 10 different "sounds"

To me it's absurd - if we are going to believe that each cable sounds different then finding sonic bliss in that mess is not going to happen - unless of course we're going to say that the wires at best offer subtle differences. Changing out the speaker cable for Nordost might make it sound better but to me it's a band-aid.

What I liked about Peter's upper rig is that the entire chain from tone arm to speaker voice coil was silver wired with the same wires (smaller strands for the smaller components but the same material throughout. Including the windings on the transformers to the silver soldering material on the point to point wiring.

His top speakers are hard wired with his cable directly coupled (you can't change the speaker cables). You essentially go from the 10 different wires to 1 wire.

No one else does this.

What I have seen people do is re-wire their speakers to match their speaker cables and get a partnering IC from the same company with the same material.

IMV if the whole chain isn't one wire type then it's a matter of tone controls for cables trying to figure out which IC or speaker cable works best with the other TEN wires in the system. One expensive wire no matter how expensive I don't see being a panacea.
