Difference bewteen McCormack DNA-2 & DNA-1 ??

I will add just a few comments:
1) DNA-1 dimensions are 19W x 7H x 15D. Shipping weight is about 55 pounds.
2) DNA-2 shipping weight is about 92 pounds.
3) The DNA-2 is laid-out as a dual-mono amp. There is a single toroid transformer, but it has separate windings for each channel.
4) The DNA-2 is not a "balanced" amplifier, but it does include balanced inputs.
5) Parts quality is, in general, exactly the same for all DNA amps. The transistors are the same in ALL models. Deluxe versions include a slected set of premium-grade parts, including Cardas hardware, Caddock and Vishay resistors, and Harris soft-recovery diodes for the front-end circuitry.
6) I don't have the exact figure, but the total number of DNA-2 LAE (Limited Anniversary Edition) amps is under 100. The LAE model came with a special faceplate (thicker, Gold lettering), custom speaker connector system, thicker output circuit boards (.080" vs. .062"), a full complement of Vishay resistors, and a Cardas AC cord.
7) With a good AC cord, performance of the DNA-2 Deluxe is very similar to the LAE model (although the LAE still has a slight edge).

Steve- many thanks from all of us. You are a class act (and I love my DNA-1, Rev. B)

Yep, I love my DNA-225, too. May have to call to see if Steve has anything in mind to sweeten its pot even more!

4yanx,

I seriously doubt Conrad-Johnson would endorse Steve upgrading the new McCormack amps, but you can take solace in the fact that many of the upgrades involved in the SMcAudio revisions have already been incorporated into your amp(I believe on par with the B revisions).
