  1. through years ive seen and heard quite a lot of equipment and systems. to be honest, 90% of them are not worth the money. even studio level gear are crap, not all, but most of it. why? i think its marketing, everyone goes after measurements and data on paper. it DOES NOT reflect real world. sure, you can measure things that will tell you something about particular piece of gear, like impulse response, but that is rarely written anywhere. for example, take tube amps, measurements are just sad compared to modern amps.....but sound great. same thing with speakers, i happen to have quite a lot of old soviet fullranges, yeah, measurements are hilarious, but still i havent found anything that can compare with these, of course i havent heard all of speakers in the world, just quite a lot. i know that there are few better than these, but at what price? one outrageous example was yamaha msp10 when they were ripped open, they sounded really sad. when we looked at them it was obvious, to make flat response there was enormous correction filter. as result phase shift was about 1000!!!!!!!! degrees through spectrum. and this is studio level gear. also what worries me is cutting corners when developing audio gear. just look here Lukasz Fikus Lampizator this guy is from poland or ukraine, modifies and rebuilds a lot of gear with tubes. perfect example how manufacturers are cutting corners everywhere possible. another example is antelope dac, full of hitech relays, dacs, filtering etc........BUT is fed from cheap ass switching psu, to top it of there is another switching psu inside the DAC itself. just imagine intermodulation and havoc between those two PSUs on other hand there is gear with just silly price/performance, like tripath ta2024. you can buy it on ebay for few dollars including shipping. and that thing sings if you fed it with proper clean supply. or even better, car battery. yeah, power is quite limited for those who have low sensitivity drivers, its 2x15w under best circumstances (15.5v). for me 1-2w have always been enough, so that wasnt problem for me.
  2. why do you want to go this extreme. just build power conditioner. its easier and makes more sense. btw - your computer creates a lot more RF junk than power in wall. then go even more extreme and build your computer on car batteries without impulse power supply, even that makes more sense.
  3. this is great idea. this type of cables sound quite good. as mentioned earlier, only thing that its hard to work with. some time ago i did small experiment. i took three cables of CAT5, braided them, striped the endings and divided into "colored" and "whites". obviously one was + and the rest -. i was blown away with clarity that they produced. later i gave them to friend who is into expensive hifi equipment, i didnt say what that was. after few days he called being really excited about them: " i started to hear this and that....i havent heard that before..." i dont need to say that his speaker cables are few times more expensive than all of my system. then i told him what were those cables......he became unusually silent... few months later i braided CAT6 cables for him. on electrical side of this: as one engineer explained that perfect clarity is due to twisted pairs, different turns ratio and fact that each wire is solid core. when multiple wires touch, in that spot are some magnetic variations which can be audible, so solid cores are better, because there aren't any those variations. only thing is that you need to calculate number of cables for your system. more power = more cables. i was enough with 3 cables = 3x2x4 pairs. thats 48 solid wires. for each side of course after all im driving 16ohms for some 4ohm systems you need to do A LOT of cable braiding
  4. i have a friend who is engineer designing stroboscopy equipment and making helluva lot of spacegrade technology. once we discussed this idea, and he said that best result would be if sound equipment was designed the same fashion as RF tech is being built. that means every stage inside amp/dac/whatever is isolated and shielded with proper sheet metal. he had some prototype where he was using this technique, but i didn't have time to listen to it. from my point of view there is little point of building faraday's cage AROUND your equipment. better to rip your amp open and isolate PSU from the rest. because crappy power supply can cause BIG impact on end result. stay away from any impulse type PSUs. once i rebuild and modified all my amps to run from car batteries i was blown away how much of difference that made.
