Hi, please forgive my ignorance but I have a question. I have a pair of M22ti at the front and will soon own a pair of QS8. I was wondering if I would see a difference by hooking them to 2 separates amps instead of one. I have two yamaha htr-5960. I would plug my inputs in the first amp and take the pre-amp of the rear and connect them to the second amp.

I don't know if it makes any sense or if I would notice a difference (and I don't really have time to test it since I moved into a new home last week).

my room is ~ 16x12

You won't notice any difference.

It's only a concern when you don't have enough power from a single receiver. Given your room size and receiver model, you have more than enough power.

Probably depends on who you ask Luc. People that are "seperates" believers will still prefer them over an integrated design with everything crammed into one box, even in rooms your size.

How can you make such a statement not knowing what the listening habits of the OP are?

I'm assuming the poster is not hard of hearing and that the room is quiet (50dB of ambient noise or better).

One M22 requires 1 Watt to produce 93dB at 3 feet. If the poster sits 9 feet away from the M22s, 1 Watt will result in 84dB from a single M22 or 87dB from two M22s. Given that it's a 100W amp, this will give the poster more than 18dB of headroom. And this doesn't count all of the other channels which could result in even more SPL.

I'm in a room that is about 2.5 times the volume posted and my 90W amp is more than enough even when I listen to classical which is quite dynamic.

Assuming is never a good thing.

Honestly it has been noted before the mathmatics might look good on paper but not always the case in practical terms. Ian noted this in the recent thread about the new Axiom amp.
