It's funny but tube amps to me run a wider gambit of sound - what I don't like about some tube amps is this midrange hump that overtime bothered me - my Audio Space Mini2SE had this sort of midrangy hump and I didn't really notice it until I had the LM 219IA. Then I went back to the Mini-2 and I could not listen to it. I sold it. You would assume the softer sound midrange emphasis would not be fatiguing as it wasn't bright but there you go. It was an EL34 amp. Plenty of people prefer the KT88 because it is generally more extended. Of course, this is one EL34 amp - the LM EL34 the 211ia didn't have this midrange hump to the same degree. The Pureaudio One is a SS amplifier that I like more than 95% of all-tube amplifiers I have ever heard (designed by Plinius engineers) and I am quite enjoying my class D amplifiers. The fact that your particular preamp is a tube or SE or SET doesn't mean it represents the entire technology. Note - I purchased a Rotel Preamp in head-to-head direct comparisons with ARC. Unfortunately, the fact that the Rotel could beat the ARC didn't really mean as much as I hoped so I wound up selling the Rotel a year later but still it does show you that you can't judge the technology because the one you happened to buy doesn't sound good. Consider that you may very well get much better preamp results replacing your Allnic with an Audio Note or Shindo, or Copeland or Line Magnetic or Cary, or VAC, or the other 5 dozen tube amp makers out there.
