What AV amplifier for 4 x b&W + centre

Maybe look for a Krell Trio 3-channel amp to do your front stage.  The use the Arcam for surrounds.  The Krell is likely very close to the Arcam sound.   Or get the Arcam PA720 amp if you want to match the sound exactly.

the Classe 5300 will have a different sound.  Cleaner and more neutral than Arcam.  Arcam has a somewhat smooth and liquid coloration in my opinion.  However, I did try Classe once in my system with B&W D3 and the sound was rather flat/sterile.  Caphill feels completely differently though.

there are other amps that would do well with B&W

Thank you for all your help to date
I went to my local dealer this morning and to my surprise they have Classé stereo amp + 803 d3 in their studio    I fell in love immediately and ordered 5300    Hope 5 channel will sound same good 

I will be pairing the amp with my old Arcam 850 ( serving as processor )    I am quite nervous about this.  
I feel that I have to start looking for a new processor 

if any of you have any suggestions please let me know 

many thanks

Questions. Do you have a budget in mind? Do you need support for 4K and/or HDR? Support fo Dolby Atmos? Room correction?

Thank you.  Definitely 4K 

I have no intention adding more speakers therefore most likely Atmos is not a must.  
Room correction sounds like a nice think to have.  
I like sharp / clear sound and use the system 50/ 50 music / HT 

would 10k be enough to spend on up to date good sounding processor ?
