Thank-you. For the OA13 cards, not surprisingly it followed my 861 V2 which is stilling besides the brand new 861 V4. The HD621 is very nice.

Just not sure why the configuration program doesn't specifically say slot 1, 2, 3, or 4 (like the older configuration program). Makes no sense to call it 1-2 or 3-4. Why on the earth they would do that makes no sense.

I haven't uploaded my new configuration into the new unit, but whatever defaults were on the Meridian 861 V4 and HD621 worked, albiet not optimized yet.

By the way, doesn't it come with a microphone? How am I supposed to do the room correction? I think I have one that came with a Denon Receiver, but for 20,000.00, don't they throw in a mic? I got a mic on my 500.00 Pioneer receiver for the bedroom...

I guess I have to find my radio shack level meter now also... I want to upload my configuration but looks like you set levels and do room config before finishing... I have a com port on a silent HTPC I use in that room, but it is running VISTA. I plan on upgrading to Windows 7... I wonder if I should do that first, I installed Window 7 on my laptopr and other computer, just not the HTPC. I think Windows 7 also has an XP compatability mode which may be useful.
