harmonic technology ac 11 power cord on classe

Hello Kadam -

I have not auditioned the AC-11, however...I have a Classe CA-101 and oh, about 2 years ago I tried the AC-10 on my Amp, CD player (Arcam CD-36), Preamp (Quicksilver-RCL).

I found that compared to the Shunyata Diamondback I had throughout my system, the AC-10 gave me no improvement other then a bit more clarity when hooked to my CD-player.

For basically same money I tried an Audience power chord and it never left my Amp.

This is not to tell you to buy Audience, just that in my opinion I am not sure that HT power Chords for the money give you the value that there interconnects and speaker cables do.
I too like HT products.

You're welcome.

I was surprised as well. I really thought that it would be noticeable improvement due to the price difference over the Shunyata Diamondback...but I could not really discern anything other then a smidge on the CD player.
With these types of things, changes vary from system to system, so give the HT a try and see if it does on yours.
But I would definitely give some other cable manufacturers a test as well, like Synergistic Research and Audience(it helped on my Amp.

For me I would put the more expensive cable on the Amp first.

But, if it sounds better on the CD player, then...it does not really matter.

Where does it sound better?
