. The A1400 is a unique amp in that it can direct as much power as needed into a single channel and Axiom's testing would show it can handle any speaker and room size, well almost any room size. Those that have the A1400 appear to love this amp and the few reviews that have been done say it is a very good amp.
Many of us are waiting for Axiom to come out with a 2 channel version of the A1400-8 |

Your room size and what you are trying to achieve I feel are beyond the Denon's capabilities. OK OK My classified ad will read as follows: Denon 4308CI - surround sound amp, recently factory inspected and approved, still under warranty! Never abused, only used for playing Christmas Carols at our annual church get together.

Oh, no, I've got a little piddly Harman/Kardon AVR-525--85wpc into 4 ohms! Woo! And I've never had it above, oh, -10 or so.

Oh, but you'll still need to use something as a pre-amp. You probably don't need the denon for that, unless you're going to go with a set of 4 monos or you're planning on driving the surrounds and center from the receiver instead of the amp. In which case you still need to dump a lot of power from the receiver into those.

The thing that is nice about the Denon is that it has 4 hdmi inputs, 2 hdmi outputs, 3 spdif inputs and 2 spdif outputs. I am using every single one of these. Oh yeah, it has XM radio also. Outside of the fact that it has a paltry 140W x7 channels its actually a pretty descent amp.

So keep using it as your pre-amp. That's not a big deal.

My 2805 works great as a preamp for my 80's.

That's 140 x7 into 8ohms but the 4 ohm load increases the output by about 45%, you are running about 240Watts into the M80s and the 4308 was never designed to run that much power out. This is why we are suggesting the seperate amps, at least for the M80s.

An Emotiva XPA-5 would probably be just fine. Solve your problem for about $800.

Is it ok to continue the new amp discussion here or should I start a new thread?
