Many years past, I carried out numerous Tube vs SS as Amplification , as a Phonostage, Pre-Amp' and Power Amp.
The Outcome being I become a user of SS Phonostage > Tube Pre-Amp' > Power Amp's
More recently over the past 5-6 Years, I have revisited the Comparisons and had demonstrations of Commercial and DIY Built Designs.
The Outcome being I have now been introduced to Tube Phonostages that I now own, as well as, SS Pre and Power Amp's I would happily own in place of a Tube Amp.
My expansion into Digital (I am a very late comer to the party) has the Outcome that I have selected a Tube DAC over a SS DAC.
There are some good DAC Comparison Demonstrations on the near horizon, so this attraction to Tubes might get realigned.
