BAT 55se vs Pass xa30.5 vs mac mc275


In a room 16X20 driving Von Schweikets with a rating of 94 and no loud listening. (db 70-80 at 13 feet). Mostly classical, jazz, vocal Almost no rock.

Any thoughts? Auditioning is difficult for me but from what I can tell they are all good performers at this pricepoint.

I heard a better BAT amp on Maxx 2 and Mac tube on Stradivari and really like them. This was just however a one-time listening for each. I too would be interested if somebody who is more experienced with these 2 amp and the Pass XA30.5 to break down the differences.
