Have you moved from tubed amplification to solid state amplification... Why?

I'll offer my input though we already spoke about it.  I went to solid state for a few years and enjoyed it.  I didn't 'miss' tubes, but I did find myself constantly wanting to improve the system.  When I got a push-pull amplifier, I still stuck mainly with solid state as I noticed improvements, but it wasn't worth the move for me.  When I got back to single-ended designs, I fell in love again and realized what I was missing.

You can be happy with solid state, but I'd advise staying away from tubes.  An acquaintance of mine has a similar saying: The best way to enjoy digital is to never listen to analog.

Switched to SS because 1. I'm a worrier. Got tired of wondering if it's time to change the tubes before they explode or some other catastrophe. 2. Tubes, IMO, tend to homogenize whatever you play through them. SS is better at textures and dynamics. 3. The expense every two years.
My preamp does have tubes. I may try some of the newer SS preamp designs in the future (Pass, BAT, etc.).

I swore I would never own tubes because of the "hassle and expense."  Well, I graduated from Adcom GFA555 II's to a Conrad Johnson MF2550 SE, which sounded great (along with my CJ ET5 preamp).  Then I took a chance on a used pair of CJ monoblocks and they just sound better.  Somewhere between nominally better and noticeably better.  More fluid, and more musical, although the CJ Solid state amp sounded pretty good in its own right, and had marginally better damping for the bass.  I kept the solid state for my b system, but for the a system, it's CJ tube monoblocks and the now discontinued ET5 preamp.   I have toasted a couple of KT120 tubes, but they are only $50 each from upscale, and I have put in a nice Telefunken 6922 in the ET5 from Brent Jessie in Illinois.  They are all approaching a year old and they still sound great and I play music 2 hours a night about 3 nights per week.  So, I am really no longer concerned about the cost of tube replacement, but I do stock several pairs of KT120's and some 6922 tubes.

Advice/lessons learned?  If you want great sound you have to have a great source.  So, I needed to upgrade my Rega Rp6 with MM Exact 2 cartridge to the RP10 with the Apheta II mc cartridge to bring that out. 

Now, I am really pleased with the sound; symphony, Peter Gabriel, Eric Clapton Live, Mozart Piano Concerto's-- all good.  If I was to go back to solid state, I would buy Pass Labs gear-- a combination of used on audiogon and new from Mark at Reno HiFi.

I am not related to any of these vendors; they are just folks who have really treated me well over time.
