BAT 300 SE integrated volume problem

Hi Audiogoners,

I just got a new BAT 300 SE 150 Watts per channel integrated amp. I'm driving JM Focal monitors rated about 89 efficiency. I'm having to turn the BAT all the way to the max to get good, albeit loud, volume. It simply won't get NEARLY as loud as with a Cary SLI-80 or a Prima Luna Dialogue II integrated!

Also, I just switched from an older Sony ES CD player to a Musical Fidelity A3.5, and that seems to put even more of a strain on volume. Does that make sense?

I'm biwiring my speakers from the BAT and I run a Von Schweidkert subwoofer from the speakers, as a Von S rep advised.

Thanks in advance for the help.
