I stayed up way too late getting setup. So I'm sleeping in tomorrow. But here's what I brought this year:

You'll notice the four π mains flanked by three π subs. Not surprising there. But what's new is I'm not running my usual amplification. This year, I'm using Oddwatt amps. That's what those two monoblocks are on the bottom shelf. I also have the remote control RDAC "passive preamp" mentioned at the beginning of this thread. It's the box up top with the "005" on the display.

This is another one of Bruce's Oddwatt creations. He built a prototype passive preamp based on my remote processor chip. The numeric display is his way of providing visual feedback on the volume setting. You can do it with a bar graph or any number of ways, or not provide a visual indicator at all. But any way you package it, I like it because it's just one single (wiperless) part between the source and the amp. No mechanical contact via potentiometer getting in the way.
