Pass XA 30.5 with Revel F 208 ?

If a speaker seems "light on octane" driven by a 300 watt amp,
that's quite a very inefficient speaker that's wasting good quality power
(Pass amp) IMO. Its never been clear to me why some speakers need to
draw so much power to come alive, just a curious observation and not
criticizing.

Thanks folks,
What Brands/models should i look at? My room size is 13 x 19 and i listen to classic rock (I enjoy live recordings), western classical music. I plan to buy a used pair of speakers to get to the higher models and brands. Budget is around 4000-5000 USd.
Thanks

Charles, the XA30.5 puts out 30 watts per channel, not 300 watts. 30 wpc could still work though, but would depend on the size of the room and the listening levels as to whether it would be enough for the Revel speakers. In a small to moderate room, at moderate listening levels, I'm sure it would be fine.

Kartikeyp,

I currently have F208s and submit they are a super great value. I just ordered a Parasound Halo A-21 to drive them.

I have stand mounted monitors rated at 7 ohms and 89 db efficiency in a 10' X 12.5' room.

I auditioned a Pass XA 30.5 and it sounded glorious at quiet levels, but completely lost it as I increased the volume.
