1. Wotan would connect to Kara either via XLR/Balanced out, or via RCA single-ended. I strongly recommend balanced, but then I have a long run to the amp from the pre-amp.
2. Sub would be a different thing, depending on the sub itself (some have ability to be driven by speaker-level connections and then synthesize the mono sub functionality). One thing you could do to leverage a line-level driven sub, would be to take the RCA output from Kara to your Denon AV, and then it’s Subwoofer-out RCA to the sub(s). Or, you might not want/need a sub with Wotan’s “control” ability; it may extract more/better bass from your current speakers… I’ve done that with my Denon AVR (fed it from my pre for when wanted to do multi-channel) in the past… but ultimately I came to the conclusion that dedicated 2 channel is for real music, and X.1 is for video (only).
3. If you did drive Wotan from the “Front” RCA outputs on the Denon, you will lose the ability that the full “stack” has for visual volume. And, you will be feeding an excellent sounding amplifier with a demonstrably inferior preamp (for MUSIC). I was faced with that exact situation 2 years ago when my Classe’ pre-amp died. I had to use my Denon AVR as a preamp. Trust me, you don’t want to do that unless you have no alternative. That lasted ONLY as long as it took for me to quickly find a used pre-amp (ultimately replaced by Kara in my case).
(Note: there MAY be an AVR out there whose audio only preamp capabilities reach Kara-level, but I’m sure not aware of any, and should they exist, I’m sure they are tons of money. I may be wrong on this, but I bet not. My Temporary “pre” while I was sorting was actually the Proceed (Levinson’s AV lineup) AVP 1 (it was many 1000’s of $$ back in its day). I got it used for only $400. But it didn’t sound as good as the Classe’ it replaced, and was only marginally better than my Denon. Kara is so much more dynamic, open, quiet, slammin’, and spatially rich than either.
More general observation that may, or may not apply for you: I’ve found that the entire “setup” in a room, for excellent 2 channel stereo with proper soundstaging and imaging is antithetical to proper setup for 5.1 (for starters, you end up with a LOT of gear and reflective surfaces between your speakers, which is sub-optimal). Yes, can be done, but why invest so much in quality 2 channel to have it gimped by co-existence gremlins that automatically come along with multi-channel, AV-oriented systems.
Great reply - thanks for taking the time to write up your thoughts. Still in the planning stages but it may happen much sooner than later. I'll work to keep the 2.1 music portions separate from the home theatre amp. Still some planning to do. At least I have my wife on board on getting a proper audio stand or two that are open shelves and preferably on wheels for easy access to cable connections.
@artur9 , I bought the Denon well before I really got into this
