McCormack DNA500 and DNA2


Hi everybody, this is my first post here and the question I'd like to ask is what is the difference between these two units McCormack DNA 500 and DNA2. I think I've set my eyes on one of these units, just don't know which one to pick. Any comments are welcome.

I have a Modwright Signature 9.0 w/NOS tubes I am putting into my system today. I will let you know how it meshes with the DNA-125.
The Modwright preamps work very well with the DNA 500. I own the DNA 500 and used it with the Modwright 9.0 preamp and then more recently with the Modwright LS 36.5 with external power supply.

The DNA 500 is great amp.
Well, 2 days listening to the Modwright 9.0 Signature w/NOS Tung Sol and Sylvania recitifer, and it sounds like a perfect match for the DNA-125 rev. Gold. This is probably the best I have heard this amplifier sound. Huge soundstage, very natural and dynamic. Beats the last 3 preamps I have paired with this amp: Herron VTSP-1a/166, Audio Research LS26, and Dehavilland Ultraverve II. Plus, it is extremely quiet, something I couldn't say about either the ARC or Herron when paired with this amp.

I bet the LS36.5 would be even better!
Thanks a lot guys, that's very valuble info. The LS is a bit out of my budget for now but used SWL might be just the right fit.
