Power Cord for my McCormack DNA-500

Paging all McCormack DNA-500 owners...

Santa was very good to me -- I landed a slightly used and very well cared for McCormack DNA-500 over the holidays. What an amazing amp! It has proven to be a substantial step-up from my Levinson 331 and really brings out the best in my Aerial 10Ts.

Here's the thing... because of the 20amp IEC component connector, I'm stuck using it with the original power cord for now. It's much more difficult to find PCs to "try" with the 20A IEC much less find one used here on Audiogon (although there are a few).

So, can any DNA-500 owners speak to the improvements your PC provides over the stock PC? I've seen lots of recommendations for the VH Audio Airsine. I love this PC and am using one on my orig Hydra. But... it took every penny I could scrape to buy the DNA-500, so a $700+ Airsine just isn't gonna happen anytime soon.

What about a Flavor 4 with 20A IEC on the component end? There is also a used Audience PC with 20A IEC. Anything else in the ~$300-$400 range that would be a substantial upgrade over the stock PC?

Thanks!

Would your comment translate to utilizing the stock cord? I never used the stock cord on my premier 350 so maybe it would be better than utilizing the PS Audio with the IEC adapter. What are your thoughts? PS Audio does not offer a 20A IEC for their power cords but instead refered me to a technician that could perform the surgery. I found the adapter on the voodoo web site and figured why not never giving a thought that it might effect the performance of the amp.

Hi Chuck -

My comment was only intended to suggest that I think you would be better off without the adapter, once you have found the AC cord that is right for you. This is especially true with high-powered amplifiers. I am mildly surprised to hear that PS Audio does not offer the 20A IEC connector as an option, but having it done by a good technician is still possible.

I make an effort to provide good quality stock AC cords with my gear, and for many people this will be just fine. However, I find that aftermarket AC cords can offer a meaningful performance enhancement, so I think it is worthwhile to audition them - much like interconnects and speaker cable.

Best regards,

Thanks to all for the positive feedback on the DCCA Extreme Ref. I did contact Don but I'm afraid even the demo is a bit beyond my reach right now. But I will definitely keep an eye on this cable.

And thanks, Steve, for your insight on PCs for your amp. I will definitely try a few!

Just my 5 pennies. I had a DNA-500 too and it was a super amp. I started off of with a LAT Internationa AC-2 MKI and was very, very happy with it. It really 'lit' the amp up to my ears. The great thing about the LAT cable is, it's inexpensive and you can test drive it for 45 days. All you loose is shipping costs (marginal).

You could do alot worse.
