what amp under a grand?

Here are just a few integrateds with HT Bypass that come to mind...
Marantz PM8004, PM15S2, PM11S3.
Arcam A-28, A-38
Creek EVO 2, 5350 EVO, Destiny
Krell S-300i
Musical Fidelity M3i, M6i
Music Hall A70.2

There are probably a lot more than just the above list. Maybe some others can add to it. Another option is to consider a 2 channel pre-amp with HT Bypass and install it between your AVR and Adcom such as the new Parasound Halo P5. Same concept. Good luck to you.

yeah the marantz pm8004 is on ebay think ill give it a shot.

Nice amp and built at the Marantz reference factory in Japan. Has the "Power Amp Direct" feature that essentially turns it into a power amp that you control with AVR's volume knob when listening to surround sources. Push the button to disengage and you control the volume with the integrated amps knob for 2 channel. It will match up well with your VA Mozart Grands. Let us know how it works out.

will the marantz pm8004 have enough juice to give the mozarts a kick?

Unless you're filling up an auditorium with sound, no problem. Your Mozarts are the same as my Bachs - 4 Ohms with a sensitivity of 90 dbw. The PM8004 is a high current amp putting out a true 100 wpc into 4 Ohms. My PM15S2 puts out 140 wpc into 4 Ohms. The difference between 100 and 140 is negligible.

It will make your Mozarts sing with no problem.
