You did not state what power amp? Assuming it is a BAT too but who knows.
Now I must state from personal experience and a number of other comments I have read that BAT and Wilson speakers are usually a marriage made in heaven IF everything else is correct. I have no experience of the BAT preamp but I use a BAT power amp to drive my Wilson's and I am wanting for nothing. Imaging and soundstage are superlative and bass response can cause bowel movements....lol.
Even at low levels for evening duty I am losing nothing and flat is not a word I could ever use.
Als suggestion to disconnect the subs is excellent and the first place to start.
You also have no mention of source? Streaming, CD,vinyl?? Could be numerous issues there too.
