Josten,
I called Outlaw today and the Tech guy told me that in rare cases, their Amps, which are fully balanced, have big power supplies and transformers and if you don't have enough voltage available, the transformer can hum. He asked me about my set up and was pretty confident that their 7x200 Amp wouldn't cause an issue, but I could easily resolve it by hooking up a bigger breaker, or running another line to my component area.
He also told me that if I ordered anything from them and wasn't happy, they'd issue a call tag and the shipping back would be free. Considering they are doing free shipping right now, there's really no risk to me.
I like the fact that their Amps are 100% balanced, unlike the Emotiva Amps which just have balanced inputs.
The 886 seems to be a pretty good unit and while it is aging, I"m not sold on the idea that 9.1 is really even worth considering. I currently run a 5.1 channel set up and I could always pop 2 addt'l speakers in my ceiling to go 7.1, but with my B&W speakers, my sound stage has always been good enough that 5.1 has been sufficient.
For $3,099 I can get a 7 x 200 watt amp plus the Onkyo 886, both new and fully warrantied. I think that's a pretty decent deal all things considered. Aside from the Antem D2V, which sells for over 5k, there aren't many other units that can do what the 886 can and has Audessey Pro Calibration.
If you know anyone looking to buy an Emotiva XPA-2 that's less than a year old and in perfect condition, let me know. I'll likely be listing it on Audiogon this weekend.
If there's an interest, I'll report back how the Outlaw Amp and Onkyo are, but at this point, I'm leaning very heavily in this direction.
Thanks again for the advice and if anyone has any addition comments or advice, please weight in soon, as I need to order before Monday to get the free shipping!
