Any good reasons to use transistor phono stage and line level preamp instead of tube ?

Ralph, I love you to death and you're the last guy I want to get in a pissing match with.
So let's just leave it at the Atma-Sphere MP3 I owned 1000ft. from a radio tower didn't bring me the musical joy that ss phono stages did. The same can be said for the Joule Electras, K&K and other tube phono stages that I tried in that location over 12 years. The MP3 picked up less radio than the Joule, that's for sure. 
If a tube phono stage in my budget existed that could overcome that damn radio tower, and let the music shine, I sure couldn't find it. Not for lack of trying. Cheers,
Spencer

Nevertheless my statement is true.

FWIW we've done a lot in the last 18 years or so since you had your MP-3 (yes- it really been that long!) to eliminate RFI susceptibility in our preamps. 
Tubes are actually less susceptible than solid state; this is because solid state devices employ diodes in the junctions of the semiconductors. So a solid state designer really has to be aware of RFI issues. With tubes you can often get away without because there is no diode inside a tube to rectify RFI and make it audible. Until of course, the RFI is so powerful than other elements in the circuit do it anyway. Because we had to meet EU directives (CE mark) and because people like you occasionally live by radio towers we had to do something about it and we did so years ago- in fact your experience underlined to us that there was a problem and so we had to address it.

I find transistor phono stages sound "harder" than the tube pre-amps. I've had both and I keep going back to tube.

@atmasphere , that's a worthwhile improvement, good for you! Maybe after ~20 years it's time for a model# change? Cheers,
