That is a wonderful system Nacho! :thumbsup:

Has anyone experience driving M2500 with a tube preamp? I have a VAC Signature MKIIa SE tube preamp and considering M2500. I have TAD E1 speakers.

My D’agostino amp got a problem, so my dealer took this M2500Mk2 to my home for me to use while waiting for the D’agostino momentum stereo. Comparing to Momentum stereo, I would say it could compete neck to neck. The stage is big with details. Bass is comparable to my amp. The only noticeable difference for me is the high which seems to be more conservative than D’agostino. BTW, I’m driving it with Arc ref6se and it sounds great!

How do those two compare in terms of price, particularly in the US (if you know)? Just out of love for the speakers, I'd love to try the amps, but just wonder what nosebleed price they might require in the US. No idea.

You mean these?
