Yes. The D7000's impedance is 25ohms with a sensitivity of 108dB/mW.

I guess I can't comment on whether the ALO's output impedance is a good match for the Denon's impedance. Unfortunately, as a lawyer, I have very little technical / engineering expertise.

I am thinking of commissioning a B22 (in part because I *felt* that it sounded great at the meet, so I guess I'm not quite all the way over to the science side yet), and if I do that, I'd certainly love to have people over for a blind test.

What city did you move to from Denver? You should've stayed for our after-meet dinner. We had a lot of fun.

Yeah, I wanted to stay longer, but unfortunately it's very hard to take any time off from work. I'm actually in LA temporarily and will be moving to the bay area pretty soon, but right now I live and work in downtown LA.

You can say that again, i hooked mine up to PJs system a few weeks ago feeding my Zana in complete distress due to ear fatigue and a strained thin sound i was getting, especially and mainly due to listening to usb computer source. His system sounded so good that I ordered his same dac with an upgraded clock above the upgrade he had and put an upgraded clock in the usb section as well. Then I talked to the modder and he directed me to a different transport that I ended up feeding digitally into a different dac that i have here....it is already like a dream just changing the transport and going from a lower range to a mid range+ older dac. I can hardly believe what it will sound like when the new one comes.

The point is, as you improve your source the difference is huge. If your source is marginal you may end up with a bad situations and even fatigue as I had.
