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.

Yes, I agree. It's basically part of a larger system which is a hybrid of stereo and home cinema 5.0 sharing the AV proc and front amp/speakers.
But the speakers and AV are given, now need to put the right amp. What price range would sound more logical here? Can you give some example of the amp matching the performance?
Thanks!
Consider a Modwright 150SE, a very great sounding amp with some warmth and plenty of power to drive, most, speakers loads, without any strain.
I would add Plinius to your list.
There are a variety of Plinius amps to choose from.
Given the efficiency of the Morels and your low- mid-volume listening, you might also consider a Pass XA30.5 or XA30.8. Would save you some money, too.
There is one thing you need to be aware of. I have done
thousend of tets in audio. In the past we connected many
poweramps to Marantz, Denon, Rotel, NAD, Cambridge, Arcam
receivers. But all these brands gave a 2 dimensional image
because the stage of a pre amp creates the new outcomming
stage. So connecting an amps which can create a deep and wide
stage only keep their stage when the pre amp is also capable
of giving a deep and wide stage.

Even when a Pass Labs can create a lot of dept and width,
cause of the Marantz the stage will be still 2 dimensional.

When your speakers are easy to drive even a 30.8 can drive
them. But the limitation of the set will be the Marantz.

This mistake is made by many people who have audio as a hobby.
The backside is that you cannot get the full potential out of
the Pass even when you still use the Marantz as a pre amp>
