Sprag, I was concerned about those same issues. And like you I am not going to spend more than a few $K on a pre/pro...things change too much albeit at a seemingly slower pace today than just a few years ago. Anyhow...my original plan was to continue using my two channel passive for music and the 7005 for HT duties. Then I popped in one of those hybrid SACD's and thought oh geez...now what (30 SACD's later). I have the Oppo 93 and considered pushing to the 95 via analog but cable cost alone would add another grand for multi channel (compared with one good HDMI). And frankly I'm plenty pleased with the dynamics the Marantz offers.
Still, I can't say I don't wonder sometimes what I'm missing but then I start thinking speaker upgrades, or a really good tube preamp...etc. So when I bought the 7005 I got it using AA's 30-day return offer. Honestly, I thought this thing was going to sound awful and dreaded the whole process. Plenty of FUD running through my mind.
As much as I value kal's opinion and appreciate him posting here, I find myself stuck bypassing all the Audessey stuff for music...it does feel like something is missing with it engaged. And I don't dismiss potential bias on my part.
I should have those last five fuses this week...the power supply fuses made a subtle change if that. I'm hoping for a little bit of magic from these. Good luck in your quest.
