Full disclosure, I was there looking for speakers, so not as focused on the amp, but we both liked the two speakers with the Macs.
Warmer, better mids and similar highs. Bass was all you could want on both amps.
Room was not ideal as dealer is really a high end custom installer, but the speakers were set up as per the SF protocol. The salesmen was a real pro and had been doing this for 30 years. Always a pleasure to work with someone who could teach you and not the other way around.
Don't get me wrong, the Dag was a very fine amp, just different sound. I could see them in a theater situation being fantastic. Gobs of power and plenty of current.
They were using a Mac pre, but did not get the model number. I asked what speaker cables, but being 67 comes with some drawbacks. What you ask, I don't know, I forget!

Jeff, I would expect that MC275 sounded more natural to your ears. They are designed to work together. Using the MC275 is always hit and miss when combining preamp and amp combos of different manufacturers. due to impedance problems. I have had good luck as have many others using ARC and D'agostino as they have better symmetry when combining tube preamp with solid state amps.
