Tube Preamp with Solid State Amp?

Honestly, it is wonderful, when you can find the combo, that is right for you. I have gone passive ( Luminous Audio Axiom Walker unit ), and enjoy my dac and tuner feeding my ss power amps directly, driving my modified Klipsch Lascalas. I do not want extra warmth, added coloration, nothing to smooth over, no loss of details, as I want to hear my recordings, as they are. For " me ", passive works. I do not hear sterility, as some folks mention. I do get a better understanding of the nuances, the textures, the emotions, the palpability, if you will, of what the musicians are doing, individually, and, together. In my experience, and for my enjoyment, this is the most important aspect of listening to music. ymmv. Enjoy !

By the way...if anyone with really sensitive speakers are considering one of the new McIntosh integrated amps (252.352), you may want to consider the high gain. Mac wrote me back and said their tube integrated amps have a total gain of 44db. The rep stated that tube hiss would be quite loud on my ZU Omen 101 db speakers. 

When I tried my former high gain amp with Solid State Pre.....noise was not an issue. 

at the end of the day it’s all about the sound that pleases the listener regardless of how you get there. i just think that up front the system should be neutral with great clarity. this puts most good speakers in play allowing one to then find the speakers that have the characteristics he/she values for their music. the flavor you might say. 
ymmv

Big John,

My second system consists of Parasound P3 and A23 with Forte II.
I have tried my Primaluna Dialogue Premium preamp from my system #1 and I will tell you it adds a nice holographic sound stage and that tube sweetness while maintaining all the detail. I think you are on the right track.
Good luck

I received a huge upgrade in sound from
NAD C375BEE integrated amp into tube preamp and solid state amp. 
The pieces are McIntosh - preamp included a DAC and phono stage versus an phono only in the integrated. The amp increase output from 150 to 300 yet my speakers found new life. The sound is more dynamic and detailed at all listening levels.
