Amp pairing for Nad m51 and focal 816w speakers

I had an A5. Depending on your taste, it may work, but I wouldn't even consider it unless I could try it in my system first.

I like the nad m51 a lot as preamp, thinking I will just get a amp like parasound a21.

Nad m51 to parasound a21 to focal chorus 816 with acoustic zen wires. Anyone have experience with this combo?

Sell the NAD M51, buy the NAD C375BEE, replace the stock jumpers with the Cardas jumpers.

My system is only for digital playback from laptop. I just got the nad m51 to be usb dac and I liked it so much as a preamp that I've decided to keep it simple and just add a amp, so no plan to sell it. I don't think I need an integrated anymore, just need a nice amp

I've been going back and forth on amp to add. I'm stuck between rotel 1552 mark 2 or parasound a23. The focal chorus 816w speakers are rated 40-200 watts but are easy to drive, so either amp would be ok I'm just wondering which one would sound better with my setup. Any other comparable amps to consider along with the rotel and parasound?

I'll also throw nad 275bee on the short list, matching with nad m51 is attractive, just not sure how it will sound with the focal speakers, or how it compares to the rotel 1552 or parasound a23
