Sound advice. I’ve used electrical tape to mitigate door rattle on mods.
Apart from the Fostex T50 RP in your picture (if they are yours) what headphone you rockin’? Own Audeze LCD-2’s Sennheiser HD800 with the felt mod, Denon AHD-2000 and AHD-600, all with a Bryston BHA1 amp. Few IEM’s but currently only use the Shure SE846
The T50RPs are indeed mine, awesome orthodynamic for the price.
My main set is a pair of DT880 Pro's with DIY tinyXLR jacks and a Q Audio french silk cable.
Portables are German Maestro GMP 8.300D's
I'm a Budget-Fi music lover stuck in Mid-Fi purgatory...
I started the "Pictures of Your Budget-Fi" and "Mid-Fi Portable Rig" threads on Head-Fi.

I got tired of all the Jerry Harvey Roxanne/AK 380 rigs posted in the regular picture thread and the pages of gushing that went on about them. While perfectly good plebeian rigs were completely ignored or even snubbed, audio snobbery is quite the thing...
I had the LCD-3 pre fazor & Conductor SL on loan from Audeze/Burson for a month and loved them, well above my pay grade though.
A good friend from Head-Fi came to visit a couple of summers ago and brought his HD800S/WA6 combo down for me to hear. It was very enjoyable and the HD800S is amazing, but I'd still take a pair of LCD's or beyerdynamic T1 instead though.
