Lucky score

. I've used a B200s with both my old MP1 and then MP2. Great amp very transparent and, for many years very reliable. Unfortunately my B200s is sick (popping very badly on one channel) so after all these years I now have a Carvin TS100 (all valve). The TS100 sounds great but is much heavier so it gets its own rack case. The B200s is lighter and will go in a rack you can still lift without breaking you back

and give you 120w per channel into 4 ohms.
Any combination of your pre-amps and power amps will be fine. However, to more easily compare them, you could try a small mixer (6 channel or more), plug them all in (eg ch 1/2 MP1, ch 3/4 MP2, ch 5/6 T3), send the main outs to B200s and subgroups 1/2 (if the mixer has subgroups) to the MV-962 (or use record outs or ctr room outs). Then you can quickly switch between the different setups. If you can split your guitar output so that it's fed to all 3 pre-amps you can quickly flick between combinations just using channel mutes or even more interesting, turn them all on together for an amazing wall of guitar
Although, in an apartment... I don't know about the MV-962 as I've not come across one but the B200s works well at any volume, I don't think I ever turned mine up past 3/4.
