Audiojan:
My experience says Thiels are way more persnickety of feeding electronics than most.
very resolving, kind of like horns
I also have a sub, To add to the drive that Thiels are a little light on
My experience of going from a 200 watt class D amp to a Pass labs ( big current) was enlightening . The pass added another 2 woofers to the sound and drive vs ICE amp( against normal advice?)
Your note on " not the best recordings" as being shrill, follows my thoughts and ears.
I added great tubes in preamp and that solved my "shrillness" issues.
SS amp with tube preamp to " tune the sound" worked for Thiels
Now, I've switched speakers and am working on the " shrillness" ,again, but to a very small part when loudness is high.
especially when you prefer very resolving speakers
I think older " crap" rock recordings are a tough nut to crack and I am trying a DAC as final tuning for the shrill/ edge
You have the PS Directstream that I was surching for, but evidently is not the solution?
Maybe Chord?
Anyway, That damn system synergy thing!! Lol
