Parasound A21+ vs MF M8 500S vs Cary 200.2 ES vs Hegel H20


Whilst in COVID lockdown I've been considering the next step for my system. 

I've been running a Herron VTSP-3 tube pre-amp into a Rogue ST100 tube amp for a while and whilst it has beautiful tone, timbre, density and the performers appear in front of me, I feel like it is a little smoothed over and lacking in excitement and dynamics. It needs a touch more air, liveliness and punch.

I tried a CJ CA200 (185wpc) integrated and a Kinki EX-M1 (215wpc) integrated and they both brought excitement and dynamics to the presentation but the CJ was faulty and was returned to the seller and the Kinki sounded just a touch dry to me (I upgraded the opamps which helped but it somehow sounded harmonically incomplete or overdamped and I couldn't ignore this when listening). Surprisingly, I didn't miss the tubes although both my pre-amp and amp sound pretty neutral and not typically tubey.

Although my speakers, Silverline Sonata III's, are rated an easy 93db sensitivity and 8ohm (+/- 10%) impedance, the extra power of the two integrated amps I tried really seemed to bring them to life. So, I'm thinking that if I keep the tube pre-amp but replace the Rogue ST100 (60wpc in Triode mode and 100wpc in Ultralinear mode) with a solid state power amp that's around 200wpc+ into 8 ohms, it might get me to where I want to be.

Obviously taking the candidate power amps home for trial would be ideal but this would be very difficult logistically, plus I will probably want to buy used in order to be able to afford the quality I'm after. Buying, trying and selling a number of amps is not something that would be readily tolerated by my wife who, although tolerant of my audio obsession has her limits.

So, if anyone has compared these amps, especially directly against each other, I would really appreciate hearing your thoughts as to their relative strengths and weaknesses.

Your observations on  Silverline Sonata III's are a bit odd to me: I also own these speakers (though I listen to a different pair now) and I've paied with with a Cary SLI-80 integrated (85wpc in the UL mode, as claimed by the manufacturer), a 12wpc Chinese SE amplifier powered with EL-34 tubes, a vintage Sansui AU-517 integrated amp (65wpc), as well as restored vintage Eico HF-81 and ST-40 integrated amps, and each of them sounds great with Sonatas. My listening room is small (I don't remember its exact size),so the power is enough for it even if I listen late at night at low volumes. Does changing speaker placement, cables and other tweaks help?
