Considering new amp - Mccormack


I've got the itch to upgrade my amps.

Currently I'm horizontally biamping with two modified Adcom GFA 555 II.

Rest of system as follows

B&W 803 Matrix SII - Recently refurbished
Sonic Frontiers SF1 Preamp
Music Fidelity A3 24 Dac
PS Audio P1000 power conditioner

Favorite Bands are:

Radiohead
Bon Iver
Fleet Foxes
Massive Attack

What I don't like about system: Raspy... especially with radiohead vocals.. The B&W combo with adcom and vocals of peter york are Harsh.

I'm considering the Mccormack amps, anything from the DNA .5's modified to mono's or DNA 2 or DNA 500?? Currently there is a DNA 2 Limited edition on Audiogon for about the same amount as the DNA 500.

My max budget is around $3k, but less would be nice, maybe I could get away with a single DNA .5 or DNA 125?

Any advice would be much appreciated.

If the DNA .5 would drive the 803's, then I maybe I should consider making an offer on the Rev A that's currently up for $1200??? Just concenred about going down to 100wpc, then again, if I wasn't happy with power, could always pick up another and biamp or get them converted to mono.

Evidently... From what I've heard...

There where two studios that remixed the original Radiohead albums (before in rainbows). Half the song given to one studio half to the other. Hence people thinking some songs bright.. etc.. Not sure if this is based in reality or not. I do know that they (Radiohead) are very difficult to play on a system and any problems on my system show up with Radiohead, espcielly in rainbows - nude. Problem is, I love the song and it drives me crazy. I've spent late nights changing out drivers, cross overs, etc.. had my speaker completely check out, now I'm down to the amps. BTW my signifigant other thinks I'm completely crazy. But then again, she was amazed that I could hear the differenct between MP3 and Wav, even when she tried to fool me.
The DNA-0.5 will do a fine job of driving your B&W 803s. If you were in a very large room and wanted to drive them to "live" levels, I might suggest a more powerful amp. Short of that, I think you would be very pleased with the match. And as you say, if you feel like bi-amping in the future, you can easily add another.
