Anything SS sounds better than D'Agostino ?

There have to be at least 20 companies that make a statement amp that is every bit as good as D’Agostino.  At that level, to say that one is better than another is of limited meaning.  More important would be personal preference, and synergy with source material and other components. 
Also worth noting that at the statement level, some types of implementation are far more expensive than others.  You could make the argument for example that statement level Pass is a much better value than statement level Dartzeel, if sonics are the only consideration.

The Soulution amplifiers are really nice as well as Spectral and CH Precision 

@inna  sorry for the delay in responding to your question about S250 versus M900u. I still own both amplifiers, and I have been so engaged with the D’Agostino in the system that I haven’t put the Luxman back in yet. I will, and it will be interesting to hear what I hear then.  My gut sense right now is that the D’Agostino will prevail for my speakers and system.  But it is not certain, as the Luxman is a great amp in its own right.

jbrrp1, I see. Thank you. I keep reading that D'Agostino are very special amplifiers.

I will need to try the switch back to Luxman soon and see what I think.  I have implemented other upgrades in my system that have me mesmerized with the sound quality, and I might be ascribing too much of that to the D'Ag. 

I do like to listen to a new piece for weeks usually before feeling I have their measure (cannot understand the camp that is constantly switching stuff fast and proclaiming their findings - - I know I can't do that confidently).  Switching back to the Luxman in the new context will be interesting, because I really am smitten with the S250 in my system now.
