The same assumption could be made in regard to tube and SS; although in a bedroom system an SS amp would outweigh tubes based on practicality.
I believe the most valid observations are those that are made "unconsciously"; for example, that's how I made my most valid observations in regard to tube and SS. Ages ago, when I enjoyed the night-life, I wondered why did all the music on "jukeboxes" sound so good; it was because that was the first high end I had encountered, plus it was both tube and analog at 45 RPM.
My very first rig was SS, as probably everyone else's was because tubes were ancient. I was still enjoying the night-life when the "jukeboxes" changed to SS, but not digital, and somehow, the music had lost it's "sparkle". I didn't investigate, just quit playing the jukebox.
Not until my state of the art (according to "Stereo Review") SS needed to be replaced did I give those antiquated tubes another try, CJ it was, and never looked back to SS since. Now I wonder if my stance on tubes, is similar to this one on vinyl?
