Pass Labs xa - .5 amps

At the moment have a loaner XA 30.5 hooked up to my Lohengrin.
with 95 Db it get's to really excessive spl's.
just amazing what this little Pass does concerning control and sheer power.
very new so cannot make claims on musicality, but i like it. remember it's all in the match.

Anyone using this XA 30.5 with 4 Ohms (86DB) spekers?
I am highly expected your suggestion becoz am planned to purchase the same for my Dynaudio Speakers.

The XA-30.5 will be fine with 4 ohm speakers, but it might not deliver the volume you require on 86dB speakers unless you are in a small room and listen at low volume.

Thanks for the suggestion and presume 280 sq.ft room can be fine...is it?

Really depends on how loudly you listen. The XA-30.5 will run out of steam at 100dB peaks on your speakers.
