Pass x250.8 vs Hegel h4se vs Ayre VX-R

I would also recommend Pass. I have a pair of xa100.5's and they are truly excellent sounding amplifiers and a great company.

Owned the X250.8 and stumbled across an H4SE, so I bought it. I sold the Pass. Hegel was far more authoritative in my system, wider and deeper soundstage, more transparent and still maintained a slight warmth like the Pass. I thought the H4SE was better in almost all areas, hands down.

Hegel's big amps are the industry's best kept secret in my opinion.  They are usually found second-hand with deep discounts.  That may change if more people hear them, but I absolutely loved the H4SE.

You are looking at 3 outstanding products.... I would recommend 1 other if you would like a different take on how they handle music. 
Ampzilla 2000 MkII mono blocks, they are about $10,000 new.

Thanks for all the great feedback.  So many amazing sounding SS amp choices.

I ended up going with MX-R Twenty (and going seriously over-budget) for a few reasons:

-- I've had a couple of Ayre amps before and like the Ayre "house sound", so it was a known quantity

-- More important for the moment, the MX-R fit in the cabinet/space I have right now, and the Pass, Hegel etc are so much bigger I would have had a serious challenge with placement and possibly heat.

Eventually I may well still try those just for comparison sake.

I have the Ayre in my system since yesterday and they really do sound absolutely incredible.  Everything I liked about the AX-5 and AX-7e, but "more".  More punch, more speed, tighter, lower bass, and all the other nice sonic qualities Ayre brings to the table.  And they're a beautiful piece of equipment in a relatively small package comparatively.
