- Trafomatic Primavera - One of the most versatile and most balanced sounding tube amps I've ever heard, period. This amp seemed to drive the Susvara with ease. It is incredibly holographic and generates the proper amount of space between each instrument and vocal to make it sound natural and convincing. Almost no grain to the music and is mostly neutral sounding with extremely smooth mids and treble. The bass is tight and does not have excess boom or emphasis. (I believe this was with stock tubes as I did not roll tubes on this)
To kind of add to this (most of this is from memory but I do remember the key elements I recognized while listening to this amp), the primavera has the best presentation of depth that I've heard in an amp so far. When you combine its ability to render depth and space between instruments, you basically get insane imaging. The primavera isn't really a super "tubey" sounding tube amp which I actually like because it doesn't sound grainy or have excessive bloom in the bass. Bass layering is crazy, you can hear every detail in the low frequency with ease.
I don't know what other details you might be interested in but let me know and I'll see if I can answer it. Honestly though, it's really an end game amp and because it's so versatile with impedance matching, gain, etc., you can truly call it quits after this one.
