I'm loving my new 325is! Went from 80i to these in about 2 weeks.
Amazing cans for 70’s rock, funk, R&B, and hard rock in general. My prior headphones have been UM2’s, DT 770 PRO's, HD595’s, and HD650’s. I'm loving the 325's more than all of them.
Source is a Rega RP1 turntable w/Nagoaka MP-150 cart, Musical Fidelity V-LPS phono stage, and a Little Dot Mk III amp.
That's a great little system!
