Anything SS sounds better than D'Agostino ?

I'm good with my little Pass xa25.  Take Sugden for example one dealer that i know of in US.  Service? Is a brand still in business or will they be around?  Those are questions i would ask unless it doesnt matter and you just replace.  

As others have noted, you evaluate equipment using YouTube? Come back when you're serious.

I enjoy my Dan D’Agostino equipment, older Krell...

As Flemming Rasmussen, designer of Gryphon, once said - Mephisto will awake dead Eskimo.
But there is much more to the sound besides power and control.
I read that some prefer D'Agostino and others prefer Gryphon.

Better, not sure. I will say hearing Luxman and D'Agostino side by side I was really happy to afford the Luxman. :)

Keep telling yourself, all can afford so better.
Luxman is fine.  Just can't drive tough loads so speaker dependent.
