Since you mentioned Shunyata.. I believe that they have power systems which consists of power cables and a conditioner. I really never had much of an expectation of replacing one power cable at a time and noticing a difference, so I took the system approach of purchasing seven power cables and a conditioner with the ability to return everything. In short, I decided to keep the Shunyata products and beg for my next meal. Attention to power has made the biggest improvement to my system, which now runs off a 300ah battery.
New expensive power cord for amp and no change in sound?
I bought new an expensive(for me) well known and reviewed power cord for my very good amp and plugged it directly onto the wall socket. After a couple of weeks of daily use I hear no change in the sound quality from a $500 cord. I don’t want to name it for fear of getting my thread deleted. You would know it or at least be aware of the company. Did I throw away several thousand dollars? Before I get the snake oil answer I want to let you know that I bought an upgraded cord for my pre as suggested by the pre’s manufacturer and am pleased with the results.
I guess for full disclosure the amp’s manufacturer said don’t bother. But I had had good luck with the pre so I thought it would be a good idea.
Anybody else have this happen to them?
