Why did you lean one way or the other

Tubes are needless me to cos all the magic is in my music and my speaker’s ability to reproduce that magic to the best of its ability.

I am not going to play random number generator with my amp.

I have indulged in the tube thing and all it did was falter at getting out of the way and let my speaker shine. (that is also my fault for getting high output impedance tube amps)

Speaker impedance relationship means I do not want the amp altering my speakers FR so near 0 output impedance amplifiers with high damping factors are what I strive for and thankfully solid state amps are tremendous at that in the 21st century

No reason for me to not have both; like many, I use a tube preamp and a SS power amp and have for many years. 

I’ve flirted with tubes then moved on. 

I've had a tube preamp and solid state amp for around 30 years.  My systems before that were solid state.  A Yamaha amp and preamp.  Then an Adcom amp and NAD preamp. I bought an entry level c-j tube preamp and an entry level solid state Coda amp.  I liked the combination better than all solid state.

I've had higher end c-j tube preamps, but ended up with a less tubey Linear Tube Audio MicroZOTL preamp.  I liked the Coda amp, so I bought a new Coda amp about two years ago. 

I'm really not tempted to try a tube amplifier.  But, I haven't heard many, so who knows.  They do seem to be high maintenance.  The tubes in my preamp last a long time. 

My solid state progression took from Technics to Yamaha, to Hafler to NYAL to Distech.  Once I tried a decent tube amp, I experienced an inviting textured holographic clarity and depth I hadn’t experience before and never looked back. 

My once stock Dynaco 70 amps have now been modified a couple of times, and I did add a solid state B&K amp and active crossovers to the woofers below 60hz to get  the benefit of the extension and bass slam that SS amps offer, but otherwise I still absolutely love what I’m hearing from my tubes.
