Ive followed this thread for awhile but hesitated to join in. It almost read like a private email exchange of ideas due to the character of the responses.
Some of what every member has posted seems factual (at least part of it, based on my experience). I dont understand the string theory bit, but that last post by Corona makes sense. I can see how some of these ideas put into practice could result in a significantly better sounding amp.
As for his comments about power cords and his speakers, I have no experience to go by. I do know that the type and design of power cords plugged into my Soundlabs (they pull one eighth of one watt) make a huge difference. It should not, but every person who sits listening while I pull one and replace with another always laughs in disbelief.
I try different cables when people I respect tell me theyre worth listening to. Thats how I found most of the equipment in my system.
I know nothing about the cable Corona is talking about and even less about the theory describing why it works. I do know that most cable sounds different from each other and some is a great deal better than another.
At one time in my audio career I refused to believe that any power cord could matter. To me, this was like kids putting giant mufflers and four inch outlets at the end of their one inch exhaust system. How the heck could it help after all that small pipe?
In spite of it seeming ridiculous, power cords make a big difference. The amount of difference depends on the equipment, quality of the system, the cable design, the quality of your in wall wiring and the service provider. Its no wonder this is the most hotly debated topic. Its unlikely any two of us have identical situations to draw results from.
My decision is as always. I test by listening and deciding if the amount of money involved is worth making the change. Not very scientific, but the music always benefits doing it this way.
