Best AV processors for under $10K

A Theta Casablanca III will give the best of both worlds.

I second the Casablanca III.

Meridian G68 will be in that price range.

Hate to be contrarian -- and forgive me if you've already considered all of this -- but I might argue that "the best of both worlds" won't be found in a single box. (Actually, may be more than two worlds, two channel preamp, multi-channel preamp, two-channel DAC, multi-channel DACs, AND video switching...).

Rather than sink the whole budget into Classe/Theta/Meridian (or Krell, etc.), you could put < $2k-ish into something like an Integra AVP (which will give you HDMI connectivity and all the latest HT codecs) and then put the remainder into a top-flight two-channel preamp. Or split between a preamp and a stand-alone two-channel DAC. You could also run video straight to your display, rather than paying for broadcast-grade video switching in the AVP. I’ve always assumed that the “best of both worlds” was best achieved by running this type of hybrid system (with the main preouts from the AVP into a HT bypass on the two-channel pre for integration). Certainly more complicated, but coming from a professed gearhead an excuse for more boxes is always welcome….

Best of both can be had in the Marantz 8801 and in conjunction with an Oppo 105 is what i consider an Audiophile and Videophile dream setup! after sufficient burn in of both units one is easily satisfied with the 2/ch and multichannel performance of both they are indeed a killer combo! All inputs are covered xlr and hdmi 32 bit dac's in both units. As a test of the 8801's preamp abilities I ran the Oppo strait to my Parasound A21 which is sheer audio nirvana! and when using the 8801 in the chain the performance was very close indeed and given the fact of Audyssey XT32 multi ch is unlike anything I've heard, sounds glowing? yeah!, but it is what it is. I'll say this the performance in this setup is the current SOTA!
