Jeffrey,I found this link for the AQL amp and it talked of the need to upgrade the caps for this amp to avoid arcing over time. Did you experience this problem with your amp?

...what Voltage your main-PS caps are. If they're 500s, they're OK.BTW they're in series for the amp's almost-1000VDC main powersupply.

Jeffrey,I'll have to check when I received the amps.
Base on the reviews I've seen this is an amazing little amp. Although knowing the crude impedance curve that the innersounds are known for, swings from 2-16 ohms. I'm wondering if there's any tweaks that can help buffer this for the amps.
I've heard of people hooking in transformers between the speakers and the amps. I don't know if they did that to help stablize the impedance the amp sees. Would you know anything about that?
You might experiment with the 4- v. 8- v. 16-Ohm taps. As you move up, the apparent loudness increases, but the amp has no more power at one v. any other tap. You'll just have to determine which sounds best overall.The transformer you write about probably is the Paul Speltz Zero. I'd listen a long time without it before spending at least $450 for the Zeros.

Jeffrey,Did you find those Zero's a worthwhile investment? What affect did the Zeros have to the music in youir setup?
Will this transformers help buffer the amps?
...the amp drives, I think to double or triple. So if you have a speaker that varies from 2 to 10 Ohms, it'll now vary from 4 to 20 or 6 to 30.Sometimes amps are more able to drive different impedances with flatter frequency responses than other impedances. If one had plenty of power available, I suppose I'd try the lowest-impedance output taps into a substantially higher-impedance transformer/speaker load. I THINK you'll get the highest damping factor and the flattest frequency response that way.
But maybe someone who KNOWs rather than I who am merely speculating will help here.
