Thanks, I've been a long time lurker
I'm interested in this post as I've just upgraded to 803d3. I've had various b&w speakers for the last 25 years but a newcomer to Mcintosh, now I have mc452 and c53 (along side an Arcam 5.1 system, bypassed). I'm loving it all! But always looking for improvements.
Just need to sort out a random high pitched click/pop through the tweeters when it all turns on/off....
