I would hope that the AVM60 would also have a cleaner signal, and nicer DACs.

Apparently not. They are both "Premium 32-bit / 768 kHz Differential-Output D/A Converters".

So any audible improvements would have to come from the increased output voltage, lack of interference from an integrated amplifier section, and balanced output connections.

Or even from better EMC practices and PCB layout which the engineers may have done and told no one about. smile

I think the only difference is the amps. They all have the same chips\Dac. The 1120 has Toroidal Power, while the 720 doesn't. All 3 from 520 to 1120 are rated 140 Watts for fronts 60 for surrounds.

I use a ADA 1250 3 channel for my front stage. Limiting myself too 5.2.2 at the moment with my MRX720.

Out of the box the 720 is 7.2 or 5.2.2, The 1120 has 7.2.4 and the AVM 60 has true balanced XLR output. To which is the reason for the AVM 60s higher price, it doesn't have the amp's though it does have more circuitry inside.

On that note if you can all of us Axiom\Anthem heads highly recommend. The ADA's and all speakers play really nicely together.

Brendo, the 1500 is better. smile

AVM60 with an ADA1500-3 plus ADA1500-8 is my dream setup. Completely overkill for my space, but you can never have too much headroom, right?

I think you need a 1500-2, in bridged mono mode, for each speaker.

I dunno... seems to me that the 1500 amps unbridged occupy a nice spot just this side of "overkill" laugh

While there's obviously no such thing as overkill, it's nice to be able to keep the complexity (and cost) under control. I'm trying to avoid a situation where I have to wear hearing protection in order to take full advantage of my system.

I agree completely. I find that while my Onk can't dish it out like the ADA, the Onk is about as much as I can take.

The 1500 is perfectly matched for the M100's dynamic range BTW. The M100 compresses within 5V of the 1500 hitting its rails. Of course by that time, ear drums will have given out. That's right around 116dBC @ 3 feet. Of course the SPL could be higher than that because my meter may be missing the true peak. I sit 13 feet away, which in my room places me in the diffuse sound field, and leads to 112dBC at that power level. That's about 9dBC more than my ears are comfortable with.
