transistor pre with the sound of tubes

"I’m not liking the idea of what people say, tubes must get warmed up first. I also am a bit worried of injecting noise."

You're reading too many audio threads. Stay with whatever you have.

NO TUBES FOR YOU!

" But I don't understand your fundamental problem to just buy a tube preamp"
The fundamental advantage of SS is you can leave it on 24/7.
You can do the same with tubes if you don't mind replacing the tubes every so often.

no transistor sounds like tubes

Buy a tube dac  black ice audio , with good NOS vintage tubes excellent value ,
or Mht orchid, Lampizator  tube dacs , also a tube preamp is easy and very little maintainence.

Or a hybrid! Rogue RP7 was a great preamp in my system. Just 4 tubes that last a very long time and allowed me to tube roll. In fact, changing just two of the four would influence the sound about 80%. It was my first foray into tubes as I wanted to try that tube touch, but I wanted it simple and low maintenance. The RP7 uses a very common tube which allows many choices in NOS or new manufacture. I now have a line preamp with 12 tubes which is phenomenal, but not maintenance free! Next stop is SS passive and/or DAC direct. This is such a fun hobby!
