Power cable for Ayre QB9

I would just use the stock cable.

When I had a CX-7, I bought a Cardas Golden (used) because that is what Ayre typically shows with. I found it to make only a very small improvement in SQ over the stock cable. I now have a QB-9 and have only used the Cardas with it. If you want to get a substantial improvement in SQ, you should upgrade your QB-9 to the DSD version - it's absolutely stunning!

Rufipennis, appreciate your response. I am thinking to try both PS audio and Nordost PC. I did find some previous discussion on Cardas not being able to improve the sound quality. Also, thanks for the advise on upgrade to DSD version. have you done the upgrade already? could you please advise how the DSD upgrade improves the SQ?

Upgraded to DSD version for my QB-9 and I use Shunyata Black Mamba CX for power cable. Expanded sound stage initially with Black Mamba and expanded sound stage more with the upgrade. Recommend getting the upgrade on QB-9.

OP -

Nordost and Audioquest are sonic matches for Ayre gear as well.

Jafant, does it mean silver plated cable are better matches for Ayre? how about Kimber? I know Ayre are one of the most tube sounding gears and will silver pated cable contribute to its SQ attributes?

I'm pretty sure AQ doesn't make anything silver plated. I wouldn't go by that anyway. Cables are a personal choice. The only way to really do it right is to listen for yourself. Your system, along with your own personal taste is what you should use to make a decision. I will say that it makes much more sense to buy a pair of IC's over a power cord for your Ayre. I can't find a PC that's better than the stock cord for any of my Ayre gear. A good IC can be a very nice upgrade. I have cables by Tara, AQ, Cardas and Wireworld. For me, I prefer AQ with Ayre. Its a very safe choice, but you should still listen to it first.

"could you please advise how the DSD upgrade improves the SQ?"

See this report:

Also, be warned that the waiting list is said to be quite long. Be prepared to be told you have to wait several months. Regardless, I'm confident you'll find the improvements far out-weigh any possible gains from power cord upgrade . . . and I don't care how much you spend on a cord!
