McCormack Upgrade reviews


I currently have a McCormack DNA-2 DLX and have read about the upgrades Steve will do at SMCaudio. It seems that everyone goes straight to Rev. A. This upgrade costs more than what I want to put into my amp right now as it is my highest quality piece and I think more benefit could be achieved by upgrading other equipment.

My question is this: Can anyone comment on the different revision levels C, B, A, and A+ as to improvements they experienced. I am considering a Rev. C right now but I rarely (if ever) see people commenting about this or the other level upgrades.

You guys know if Steve is planning to do upgrades on the McCormacks produced after C/J took it over - like the DNA-125 or 225?
Steve told me he will not be offering revisions for the new amps. Understandable since McCormack's now owned by C-J, but Steve also told me the new amps already incorporate parts comparable to his B revisions so his revisions aren't quite as necessary either. I've got a DNA-0.5 Rev. A and it ain't going anywhere any time soon.

As for David's situation, it's not like the DNA-2DLX is a slouch of an amp and if there are other aspects of your system that are more limiting I'd start there and blow out the DNA-2 later(which I would definitely do). It all depends on where you perceive the weakest link in your system to be, but the Revisions are expensive and you need to assess what else you could do in your system with that money. Best of luck.

By the way, anyone know the difference between a DNA-2 Rev. A and a DNA-2LAE?

I'm confused.

If Bundus is right about Deluxe models already being at level B, why would they list prices for doing revisions C and B to a Deluxe amp? Based on all the great things people have to say about Steve McCormack, I doubt he would offer revision levels that were not improvements.
David; you should call Steve at www.smcaudio.com and get the "skinny" directly from him. In my talks with Steve, he indicated that the Rev. B would be an improvement over the DLX, and that he rarely gets requests to do Rev. C. The DNA2 is a big heavy amp and shipping cost is high, in addition to risking damage to the amp, so it really wopuldn't be worth it to me to send it in just for Rev. C. I think Rev. C is sort of a building block for the higher revisions.

2nd, I agree with Tim (above) in that the DNA2DLX is already an excellent amp and that if you have weaker links in your system, maybe that's where you should put your money. Cheers. Craig
