Stereo power amp for $10k


Please help choosing a good stereo power amp to put between Marantz AV7702 and Morel Sopran speakers (4 ohm, sensitivity 91.5dB, nominal power 250W).
Main criteria: good audio quality, warm & deep sound, listening mostly to instrumental music and vocal in low-mid volume.
So far shortlisted to three options, all around $10k:
1) Pass Labs - either X150.8 or X250.8
2) Krell Duo 175 or 300
3) Burmester 956 mkII

Which one of the three would you recommend? Anything better with similar spec and in the same price range?
Thanks.

That are the right words; waste of money. This is a mistake many people make.

Still the most common mistake is that people spend a lot of money on speakers and a lot less on amp, source and cables. Many many people play at an even low level of the full potential of their speakers.

I use a mirror to make them understand their mistake. When you bring in a better amp, source and cables they are often stunned. This is how audio needs to demoed. People need to be aware what is missing!
There's just no sense in spending $10K in this set-up. If the Marantz unit MUST stay then why not match it to a Marantz power amp at about the same price point. Use the difference for some of the really sophisticated new tweaks that can radically improve any system. I recently went to the Rocky Mountain Audio Show and was impressed with the improvement that tweaks make even in $100,000+ systems.
I like Melbguy1's idea of a very good integrated, where you can bypass the integrated pre when watching movies, and switch back to the integrated pre for 2 channel. Best of both worlds.
I agree with those who posted that a $10K amp would be wasted in this setup. I would only consider an amp of that level if I had the Marantz AV7702 running through the Cinema or HT bypass of a top quality stereo preamplifier.
At this price range, You may add BAT VK-600SE or Vk-650SE (used one!) to your wish list. You speakers are pretty good. I heard Pass labs X250.5 and Pilinius amps in the shows, they are very good. However I found BAT vk-600se to have a better resolution, dynamic and especially much better Bass with a more defined control of the sound edges. I also tried Krell EVO402e which was very good too but its sound is too analytic and cold, even thought it has an excellent bass.
That's why I ended up with BAT vk-600se which its sound is also more on warm side of neutral. It is obviously based on taste and is all system dependent ...

good luck.
