Can it really be that I'm the first new member in more than two years?
In any case, I've been in and out of audio for 30 years, and in the headphone hobby for the last 5. I picked up a little NIB Stax 2170 bundle two years ago and enjoy it tremendously when I use it (as opposed to several Sennheiser, Audeze, Hifiman, Beyerdymanic and AKG's). Now looking to go further up the Stax tree with a lightly used SRM-353x / L700 Mk I, or new in box local stock SRS-5100 (SRM-353x / L500 Mk I) for about 20% less. Both are storming good deals, with local support vs better earspeaker being the deciding factor. My search on the 353 led me here, so here I am!
