I did add the centre in the DSP but there was no easy way to use it at first. So I was just using the receiver to drive the centre and surrounds. I've more recently added a used 3 channel amp which for the centre channel is connected thru the DSP. I will soon be swapping out my receiver for a used preprocessor.

Hi guys,

I recently added a 1500 series amp with 8 channels to my system. I had been running a 1400-8 since 2008, however some of the channels failed, more than once as the amp was upgraded and Axiom stood behind the amp all the way through the process and gave me a very generous option to upgrade from the 1400 to the 1500 series. I am running a Denon 3808ci receiver with a v2 7 channel Axiom ep80-qs8-vp180-800 system. Overall I have preferred the sound from the Axiom amp infinitely more than the Denon, in my room; however, the biggest difference I noticed was when the channels supporting the M80s died. There was just no contest in the comparison between the Axiom amp and the Denon internal amplification, it was killing me just to listen to how anemic it sounded. My surrounds I believe are mounted a bit high so I'm not clear about how important having the whole 8 channels driven by the digital amp is, yet my sense is that the soundstage seems more integrated with the 1500 amp driving all channels than when I had the Denon/Axiom amp combo in force.

I was using an older model Denon receiver before and totally agree that the separate amp is a big improvement. I also agree that this is most noticeable on the front channels but this may in part be due to my relativity lower quality (non-Axiom) surrounds.

I just ordered an ADA 1500-4 for my LFRs today, can't wait. Brent said it will take ten days to build, so in about three weeks I will be happy happy!

Congrats! We look forward to hearing about you hearing it!

I'm looking forward to hearing it too, but it sure is taking a long time to ship.

they build the amps as orders come in,
then Andrew takes them home for a couple of weeks to ensure everything's ok...
...and then they're shipped.

Oh...that sounds good. Maybe they should change the "ships in ten business days" on the order page. Not complaining just saying!

Brent twisted my shoulders on an ASA1500-3. Should ship this upcoming Friday (7-5). I vacilate between really excited and reserved/skeptical. I'm looking forward to the 30 day trial for sure. Will be looking for a marked improvement in soundstage/imaging/dynamic response at moderate levels. I don't expect much at low levels, and I'm sure I'll experience the difference at high volume (due to the huge room my setup is in- well over 5000 cubic feet).
I'll let you all know what comes of it!

Look forward to your thoughts!
