Which AV Reciever to run Bose 901's,

Trying to run Bose's 901's is a pain
with some av recievers.
Seems that you need a high end reciever w/pre-out
conections due to the Equalizer of the bose.

Any ideas on how to get around this besides
getting nwe speakers?
they actually perform best when the equalizer is placed between a pre amp and amp, as opposed to using through the tape monitor switching. in any case, the more power, the better.
If you have a tape loop you can use that?

With Bloes 901s does it really matter?
