Best amp for kappa 8.1

Thanks for input.
I'm a little old school but have heard some surprisingly full sounding class d amps.  I'll update just wanted some input.   Might happen across a deal on larger Aragon.  Trying to move past previous good match with luxman m117 and original kappa 8 years ago.

Thanks all for input.  I'm going to limp by on some possibly underpowered good old class and while I research and save for my"ultimate" amp.  I have learned some restraint in the last thirty years. Scratching an old itch.
