Dan D'Agostino Momentum amplifier- which preamp?

Audio Research Ref 5se is a great combo with Dag amps. Tested them in house. Best of tubes and solid state.

Anyone run Dan's amp(s) with a tube preamp?

I know an audiophile drove his Momentum Mono with ARC Ref5SE. It sounds very good but impedance not perfect match.

First your Aviors are fantastic speakers. I assume you have them properly set up and your room treated if necessary?

I've heard my dealers Aviors with a Nagra Jazz tube pre and a Nagra Classic (ss) amp. Absolutely fantastic. Transparent cabling.

My Rockport Altairs sing with my Robert Koda K10 and Ayre MXR's. Again Transparent cabling.

Not sure what cabling you're using...but this maybe be a key ingredient with your Rockports...

Aldenberry-

another + vote for the ARC Ref5 SE. Make certain that you are using Transparent cables and Power Cords!

Keep me posted & Happy Listening!

You guys are breathing air at a higher altitude than me, but what is the problem with the D'Agostino Pre, apart from price of course?

I have heard the D'Agostino amps on a number of occasions and the best demo I have ever heard was his Pre and Monoblocks with Wilson Alexia speakers and I am not a Wilson fan. People were looking at each other, wide eyed with awed astonishment. I am sure better systems exist, but I haven't heard them and I have heard more expensive ones with Magico speakers and Dartzeel amps, for example, I really did'nt like.
