I have been using a Plinius SA 102 for the last 18 months (love it so much I bought a second unit for backup and bi-amping). The unit is a 2001 vintage. I bought it recapped. It's the most satisfying amplifier I have owned and has basically put an end to my amplifier search. This is coming from someone that has owned Gryphon, Pass Labs, First Watt, Musical Fidelity, and Parasound JC series.
The Plinius is definitely better than anything I have owned from Pass Labs and Parasound. I would put it on par with Gryphon Essence amp even though the sound signatures are different (Gryphon is cleaner and Plinius is sweeter). The Plinius has also been trouble free. I think going for older high end SS amps is a great way to get into high end amps without breaking the bank. My approach now is to go with a highly regarded neo vintage amp and use the savings to get the best sources you can afford.
