20 Year Old Amplifiers compared to 2017

I like to listen to a lot of different components in my system and can't underscore enough system synergy. That said, my biases lean heavily to the tube side of things and vinyl- keep that in mind when reading my comments. I recently ran an interesting test where I put up a new First Watt F6 vs a Bedini 25/25 that had been recapped.  Both 25 watt systems into 8 ohm doubling into 4 ohm. To my ears (and biases), the Bedini heartily outperformed the F6 being much warmer and relaxed.  To me the F6 was strident, thin and just to linear- a feature to one degree or another of all the solid-state gear I've listened to over the last 40 years. But there are listeners (one a good listening buddy who loves his Pass amps) who prefer that "sound" over a warmer tube sound which is great, as long as they are pleased with their outcome.  Btw- the last three years I've been listening to bi-amped systems in my primary rig- tubes on top and solid state on the bottom (vinyl, tube phono and tube line stage).  I can go into lots of detail on the tube amps I've rolled through but this thread specifically asked about solid state.  If the F6 represents a reasonable current state-of-the-art SS Amp and your biases lean towards a warmer sound, then at least one 40 year old SS amp can compete with today's high-end.  The Bedini amps, specifically the 10/10 and 25/25 to me, are really special and are the only solid-state amps I have been Happy listening to on a consistent basis. The 45/45 and 100/100 were good but in the end I let them go along with the F6.
