I have modified Fostex T50RP's (the Mad Dogs from Mr Speakers) and AKG Q701's with a Zu cable upgrade. I've also got a Schiit Asgard for amplification if it's needed and will likely be another purchase or two for my home use. I also have access to some older Koss electrostats (ESP-9s I think). Let me know if anything sounds interesting.
Also, I could certainly make some cables for the meet if anyone would like to try some different RCA's out.
