How far have ss amps really come in the last twenty years?

I have owned and enjoyed my Jeff Rowland model 8 ( recently modded and upgraded by Jeff to the last version) for many years. I recently had the opportunity of comparing it ( after mods) to a few of the current ss models from Gamut, D'Agostino, YBA, Parasound, Sim audio, CH precision, Constellation,PS audio,Pass Labs  and Musical Fidelity. The results were very interesting, because to my ears and in the systems that we did the comparison, the Rowland held its own against all but the most expensive D'Ag and CH amps. Even those were only very slightly outclassing the Rowland in the areas of top end resolution...and a tad in the bottom end resolution. Now the thing is that the last revision to the Rowland 8 was designed by Jeff over ten years ago! 
So, my question for those more technically inclined than myself is...how far has the design of ss amps come in the last ten...or even twenty years?

a lot of manufacturer’s now depend on fancy casework to attract the hobbyist and to justify the very high pricing structure.
They seem to know where their customer base is and design the casework appropriately...regardless of the technical merit..or the actual SQ. All IMHO.

Ditto.
And there’s a lot of these "Glitz Queens" in audio, they think if it looks the goods it must sound the goods, and ignore even if if their ears are telling them different (or they can’t tell).
They’re usually the same ones that put these "glitzy" components up on just as "glitzy pedestals" in between the speakers (unknowingly ruining the stereo imaging) so they can gaze at them in wonderment and awe at what they've purchased while "trying/pretending" to listen to music.

As Stringreen stated, amp designs have not changed so much in the last twenty years, but quality of parts has.

You can get a mind blowing upgrade in the same amp, by upgrading capacitors, diodes and resistors without changing the design one iota.

This goes for tube amps as well. Presently I'm upgrading a tube amp by changing to much higher quality capacitors.

Exactly right, in my opinion and experience.

This post is Awesome and has a fun amount of Drama! 

Can Audiogon update these forums so that pictures can be added in them?

I’d live to post my recent audiology examination and pictures of my current equipment, to share with others.

Better yet, if I had a lot of equipment and opinions, I’d love to have others come to my home and listen to the four different solid state amplifiers in my system, and tell me that they all sound the same—BEL 1001 mkV, Plinius SA-100 mkII upgraded and updated by Vince Galbo, Aragon 8008B, and Benchmark ABH2–they all sound good, and very different from each other in multiple aspects. And I have two operational systems with the same Loudspeakers.
