McCormack DNA .5 and 1- big difference?


I've got some B&K amps (ST-202 & Sonata EX-442) but a chance to pick up a McCormack DNA at a good price has arisen. Trying to pony up some spending money in case it's a wise choice.

I've lusted after the DNA 1, this model is the .5 however.

Looks like a slightly simplified board design internally, and power doesn't seem to be that reduced- advertised 100wpc/8 ohms for the .5 vs. 150wpc/8 ohms for the 1.

Looks like neither are a dual mono design- which I like in my EX-442.

Would the .5 also run cooler?

Need to power a variety of speakers- Dahlquist DQ-10s, aDs L1230s, AR 9LSIs, Vandersteen 2Cs and Thiel CS 2s.

Shakey,

Good to hear from you. Yes, I'm still very happy with the amps. Can't beat them for the price.
I own a DNA .5 Deluxe and it is hard to fault at all, being musical and revealing yet smooth. I bought it after reading user comparisons with the DNA 1. Most stating in base form, the DNA 1 is very good but the .5 was something a bit more special, even more so if a Deluxe or Rev. upgrade. I personally wouldn't spend more on the DNA 1 unless I really needed more power vs. the .5's refinement.
The DNA .5 is the better sounding amp and it has plenty of power to handle almost anything. I have owned all of the DNAs including the .5, 1 and 2. I have a standard .5 which I think outperforms the 1.0 Deluxe.
The .5 always had the reputation of being more refined than the 1. Yes, the 1 has more power, as does the 500. But unless you really need the power I think you would do better with a .5, most especially if you can get it to Rev A status.

The rev A versions of these amps are a whole different breed than the standard or deluxe versions.

Enjoy,
Bob
If you can buy a 0.5 Rev a for the price of a 1.0 dlx, then one of the amps is incorrectly priced. The Rev A of either is an entirely different amp and competes way above its "weight".
