Bye-Bye Simaudio Moon Amp

THE SITUATION: I have a Simaudio Moon 5-Channel TITAN amplifier that I wanted to pair with my Simaudio Moon Evolution CP-8 preamp multichannel processor.

THE DILEMMA: The amp is a giant and does not come close to fitting in my media cabinet.

THE SPEAKERS: I am powering Focal Chorus 836W front left and front right with matching 800VW center channel along with two Mark Logan in-wall ceiling speakers for rear surround.

THE SOLUTION??? I need to replace the Simaudio Titan with a "normal" sized amp. My budget is ~$3000-4000. Would love to get some recommendations from my fellow Audiogon'ers. I would even be open to ditching the Simaudio CP-8 multichannel processor and getting new separates or even an integrated.

Thank you forum peeps!

If I can't go big, I'd go home. Kidding aside, NAD top of the line receiver sounds perfect.

Class D sucks.
My Sunfire 300 stereo amp sucks so much, every time I tried to upgrade it, opted out always keeping it!
There's no good multi-channel amps on Agon right now, I think I will just sit around and wait. Also just wanted to mention that the Moon CP-8 processor is the best sounding processor I have ever heard. Nothing comes close. I have tried it with many different amps and it always shines compared to any other processor I sub in. I love it so much, I have two of them (even though they only have HDMI 1.3). I just switch my video directly from the source into the TV. Any other amp recommendations for me before I eeny meeny miny moe it?
i had a Krell Showcase (125w per) and loved it... can be had for under $2000... if you need more power than the S-1500 (150w per) for about $1500 more.
