Pass XA 30.5 with Revel F 208 ?

Hi Kartik,
I suggest you stay at or above 90 dB for your new spkrs.
Among coincident spkrs. There is Coincident Total Victory ll Full Range Speakers on sale on A'gone right now . You may consider Total Victory V which is current model ( 95 dB) .Earlier models were Eclipse and Total Eclipse which are worth considering you are looking for a good used pair .

Another very good one to consider is Aerial 20T V2 ( or even V1) ( sensitivity 90 dB) , but you will need to up your budget. But you can be set for very long time with your Pass XA30.5.

Triumph Extreme II are small monitors with lower freq at 45 Hz. The room size is not small being 13 x 19 ft. Triumph Extreme II cannot do justice to high quality of Pass XA30.5 amp.
