We all have our own cable stories....and Tommy is no doubt correct that it is pretty hard to covert true believers...on either side...one way or another.
Here is my story. I purchased a Halo amplifier and a buddy suggested I specifically try a Shunyata Venom HC power cord....and if it didn't improve things, send it back. So, I bought one...but rather than put it on my amplifier, I put it on my disk player, no improvement. Then I tried it on my preamp, no improvement. By the time I put it on the Halo, my mind was pretty well made up...but low and behold, it seemed that the bass was better. Over the next few weeks, back and forth with the stock cord and ultimately I decided to keep it and leave it on.
Then I bought a 2Cherry from Tommy and was using the Shunyata. I asked Tommy for his thoughts about the sound with the stock cord; he sent me the link above. By now, I was pretty familiar with the sound of the 2Cherry + Shunyata on a couple of tracks...switched to the stock cord....no difference. Spent the next week going back and forth and as of now, I'm using the stock cord and will probably sell the Shunyata along with the Halo.
You might wonder, did I go back and retest the Halo with the stock cord...so far no....the 2Cherry sounds so darn good that Idon't want to take it out of my system.
Conclusion: Not sure I have one....but when it comes to any of the Cherry Amps...I'm pretty sure you are not giving anything up by using the stock cords.
