Yeh I’m jealous, they’re just so different to any dynamic set I’ve heard. First ones I ever heard were the SR5 ones I mentioned and they’re nearly 50 year old headphones but the music coming from them was just effortless. I had some really really old set of non-Pro lambda as well. That T1 amp had two Pro holes and one non-Pro hole and ya didn’t have to hook em up through the speakers.

Ah man I really wish I had my Stax stuff still!
