There are some excellent intergrated (tubed) and that might be the way to go. $eriously. (You’ll need some serious bucks for all separates.)
Here are a few.,,,,
PrimaLuna EVO 400 Tube Integrated Amp.
Manely
Rodges High Fidelity (I have and have kept )
VAC
And a lot here on Agon
A friend has your speakers and uses the PS Audio M1200 mono blocks. 600w into 8ohms. He’s excited like an 11 year old. No pre for him as streamer/DAC goes directly to Amps. He reports low volume better too.
