Do high dollar mono blocks truly improve the Sound Quality over the mid tier amps

I used to work with a guy that bought a pair of CAD 805s.  He was constantly going off about how it was like "being there."  However, I never went over to listen to his system.  In retrospect, now I wish I would have.

I’ve had many Classe pieces in the past: ca-200, 3 of their preamps last 1 being the cp-60, and the last amps being the ca-m600 monos. I didn’t like the newer Classe products and I didn’t like the thinking of Classe was going to be in business tomorrow. So I went looking for new amps a few years ago and went with the ps audio amps, better performance, and I know they will be supported next year and probably for the next decade. The m600’s didn’t sound bad, they were warm sounding like all the Classe amps before them, but I didn’t like all the fan circuitry that could go south. I would buy another ca-200 or even a cam-350 pair for my 2nd system.

I would consider eliminating the preamp as you have the MSB reference Dac. I would also recommend trying a pair of MSB m205 monos. I went from D’Agostino momentum m400 with momentum pre and a discrete Dac to a premier and s200 and am loving it. The pairing of the MSB amp and Dac is great. I will soon upgrade to either the ref or add the digital director.
