This is my first reply to this thread, which by the way, is a terrific thread.
The picture I posted is a former SR80. The cups look like others I 've seen on the thread. They are black cherry that I got from a Canadian guy on eBay. I also fully vented them. I like to do a full vent and then back them off with felt pads attached in the cup, if I do that at all. I like the boom sound with full venting. I also added a Grado 8 conductor cable. The sound is the best of all the phones I have.
Question: I see a LOT of different cups on ths thread. I haven't read the full thread. Is there a list of people that make cups? I have a pair of Grado RS2i on their way and intend to use them as a reference point.
I love those cups! Ha Ha
