Is there anyone who came back from tubes to SS?

I own a CJ PV12 tube pre-amp. Great sound, but the tubes get expensive after a while--now selling to make room for new A/V preamp. To get the best sound you have to leave the unit on all the time--since it takes about two days for the tubes to reach optimum performance levels. You also have to put up with some "tube noise" hisses and high-pitched tones. Leaving the unit on all the time shortens the tube life. Not to sound too negative, but I want you to know what you are getting into. Bottom line, if you love the sound, you can probably live with a few inconveniences.

I sold my Rogue Amp simply for more power than its 60 watts. I got a great deal on an Accuphase P-450 SS amp. I miss the sweetness of tubes but I cannot argue with the raw horsepower of this beast. I still have an Air Tight tube preamp which I would be hard pressed to part with. If my budget allows, I may eventually get a tube amp with some 'stones' but Accuphase is the best SS I have heard. If I were to go back to a SS preamp, I would go for a balanced one or not at all.

Yes, I replaced my CJ Premiere 11a (tube) with a CJ MF-2500 (ss)amp. More bass with the 2500 compared to 11a, however, significantly more power. I felt the 11a had more detail in the mid to highend however. I currently run a CJ Premiere 17ls pre amp with Thiel 3.6's and audioquest cables. I highly recommend a tube preamp with ss amp combination; best of both worlds, or so I've been told. I am looking at possibly replacing my MF 2500 with a pair Premiere 8a mono blocks. I have not had any problems with tube noise or the like. I can not comment on any of the preamp / amp combinations you have asked about; sorry.

I have been back and forth numerous times. Overall i personally prefer tubes. I had VTL MB100's in the past, and at this time i have Rogue 120's. I mostly listen to jazz and blues.

I've been there but not back. ;-) Someone commented about tube hiss and high pitched tone. The slight background hiss is normal for a tube preamp but not the high pitched tone. That indicates to me that one of the tubes is oscillating and needs to be replaced or something else went south in the preamp. I had this happen to me in a CJ PV-12 preamp and replacing the bad tube cured the problem. As for hiss, I've owned three different tube preamps and they all hiss slightly but only noticeable if I place my ear right up to the tweeter. My Adcom GFP-750 preamp is very quiet in the background like most modern ss preamps but it doesn't have the soundstage, air, or transparency of the tube preamps that I have owned.

Currently using ARC LS16 tube preamp in combo with CJ Premier 11a tube amp driving the smallish Thiel CS 1.5 speakers. Previously owned Classe CA-200 ss amp. Good amp with more bass slam but wanted that "tube magic" so I sold it.
