Power Amping an Integrated Amp

Gkr, thanks for your response. Nice to know you had the same set up. You're right that the ADS's have a high sensitivity. Doesn't happen often but I have flickered the Power Guard "reds" on the 6200 at times. It's that headroom waiting in the wings that I want to know is there. A master cut of Tchaikovsky's 1812 with the cannons blasting a hole through my listening room wall is epic. But, with a scotch or two on board and that volume dial within reach, there's a red glow in the room seen from down the street !!  All in all I'm content and am not trying to chase absolute perfection. I just thought the 270w going through the pre on the 6200 would give me a sum gain. The 7270 just sold anyways so I'll reassess when I get the amp back from tuneup. I auditioned all the speakers of prominence in 1980 when I bought this equipment. I kept coming back to the ADS's  for their overall listening pleasure. One thing that's changed and it's a shame, but you used to be able to peruse any number of audiophile stores and audition equipment and speakers by a/b comparison. They're few and far between, at least where I live. I'd like to experience other high end systems to appreciate what's out there old and new but it's tough. I'll keep learning from the pros on this forum. Thanks again.
