I've been hardcore tube for more than 10 years now. I've owned so many designs using different types of tubes, I've tube rolled, played around with different gear combination, etc. I love tubes.
I've also gone through countless pairs of speakers.
My experience with good quality SS amplification is nowhere near as much as tubes. However, there is something I really like about SS power that I still haven't heard a tube amp do.
To my ears, it's a different type of presentation compared to tubes. This characteristic adds it's own kind of drama to the music that I really like. I'm talking about that sense of power I hear on good SS amps.
I've tried SS on 83db/w/m speakers all the way to 104db/w/m. Even 120w/ch SS made my Klipsch La Scala (104db) sound extremely powerful with insane dynamics and weight to the sound. A powerful push-pull tube amp is the only way to come close to this on the La Scala. But it also has it's own kind of magic when running low powered tube amps in SE or SET config all the way down to 3w/ch.
Powerful is the only word I can think of to describe the SS sound. Dynamics swings, weight, power and bass is closer to what I hear in live music. People talk about tube magic. To me, this is SS magic. At the moment, I'm running RT1000p on 120w/ch NAD combination and I'm in heaven. Maybe in a few months I will try my LSi9. The only tube in the signal path is the buffer stage in my cd player (Original CD-A8T).
I have to say, I enjoy SS as much as tubes. Each have their own unique sound to my ears. I will no longer limit my choices of amplification to tubes. I plan to try a high end SS amp for my next purchase.
The only speakers I feel are much better on tubes are Fostex and Lowther single drivers. I was able to get SS to sound excellent on them by using a gainclone.
I guess that's all I wanted to say. Make sure you guys keep your options open in this audio journey and enjoy the music as much as possible. A lot of times you end up loving a set up you thought you never would just a year ago. I know some people are die hard tube heads (I was one of them), but SS is just as enjoyable. There are so many stuff out there to try (new and used). I'm going to play around with SS again. Audio is such a great thing.
