Class D Technology

One heck of a lot of information, too much for my poor head!
I am in the market for new amplification, moving on from my trusty Krell KAV250 and was considering giving class d a try again. I say again as about 3 years ago i tried a pair of bel canto 500m mononblocks and found them to be so cold and sterile that I could not stand them.
So have class d moved on since these or should I stick to a monster class a like a bat vk500 or ml product?

Ok so I am way too lazy to read ALL of the posts in here but scanned through a few.
I was probably in the group pf class d naysayers due to a bad experience a few years back with a pair of bel canto 500m monoblocks that were basically, well soulless, inert, etc etc.
Now after a very positive upgrade of my ht rig from a pair of emotiva space heaters to a single nuforce class d i am ready to be convinced.

so any sensible recommendations to audition for my system which I have to say i am very happy with right now but i am always open minded.

present is esoterIc sa-50, ARC LS2 pre, b&w 804d and BAT VK600SE.

BUDGET would be max $5k for amp

thank you
 

It is the NuForce MCA20 which is based on the sta-100 modules I think?
Various reports state they only get better with burn in time and if that is the case then I will be even happier!
Last night we watched terminator genysis which is very heavy on gunshots, explosions and all round action and the sound effects were truly stunning with our full 7.1 system, vast improvement over the old Emotivas, and this is with barely 20 hours run time on it.

Red Dragon s500 under serious consideration!
Read the reviews and like what I see
Now to find one......
