I'm looking at used Arcam AVR's from the AVR 100 to the AVR 350. Of special interest are the AVR 250 and AVR 280. Right now they would have enough power for my Monitor Audio stand mounts. In the future I plan to get some Magnepan MGMC-1's. I don't think the AVR 250/280 would have enough power and, it would appear, the AVR's don't have the ability to add an amp. That is, unless the bi-amping abilities of those AVR's, on their own, would provide enough power. I know nothing of bi-amping, in general, or bi-amping using a receiver.
Another, low cost, option would be to go with the AVR 100/200 and add an external amp, which they, apparently, can do when I add the Magnepan's.
If I jump up to the AVR 300 or AVR 350, I think either of those would handle the Magnepans - they would just cost more.
I listen to mostly classical music at fairly low levels in a small room. The wife would like an occasional movie which is why I'm looking into AVR's. She seems to be taking an interest in the sound also and the Arcam seems a good resolution for both our tastes.
Thanks for any input.
