I have, but it is very long ago - like 2 years or so … at our local store around my corner … not the best conditions … out of a Questyle CMA 400i, if I remember correctly - not the most analytical DAC/Amp, which could have helped both headphones
I was a huge fan of the T1 Gen2, but also was for the 1990 Pro, before I knew better - so take it with a grain of salt
If I remember correct and this is with the A-Pads on the 1990 Pro … wait! I have commented this somewhere else!
this is what I wrote a year ago - LoL:
“1990s are a tad less wide in soundstage. Imaging is perfect on both
T1 extend less at lows than 1990s with the “balanced pads” but are way better controlled
with analytical pads the lows are very good controlled and are maybe less “fun”… more real?
Midrange is superb on both
highs are Beyers Highs - what I like.
Timbre on both is excellent.
Both are very fast.”
so better ask someone else
I don´t get the design of the T1 Gen 2, they really could modernize it
