Amps in the same class as Pass XA.5 series

Compared to Pass XA200.5 - Plinius (Reference), BAT (VK600SE) and Spectron (monoblocks) - all have very similar seductive "musicality" and ability to convey power of full orchestra realsitically. Would love to audition new Mark Levinson class D amp - #53 (@ $50k/pr.)...

Thanks for the replies everyone. There is some diversity of opinion but as usual some strong opinions about Pass XA.5 amps. Class D amps are gaining some supporters too.

Is there something fundamentally different about class A amps or can a class A/B amp provide that warm, effortless musicality?

My Edge is A/B, so I'd have to say done right you can have your cake and not melt your ice cream too.

I would love to see comparisons of the XA.5 series versus the Gryphon Antileon Signature or the Colosseum. Maybe it'll have to be up to me to do that since I don't see many Gryphon owners here.

McIntosh MC402 is an excellent solid state preamp
