The little square in the metal mesh backing gives it away.

Does the hard edge cut into the headband material or leave marks? Maybe some kind of soft material might prevent that. Maybe it’s fine. Looks cool!!

That is one helluva picture! Wow!

I use high end headphones and an hdmi audio extractor for gaming but it definitely doesn’t help. I suck. But it sounds great!

Firstly, I really hope you feel better soon. I have loved ones that struggle with mental health and I think anyone who is sane is also struggling. I am sure it is not the same as what you are going through. The world isn’t making it easy for anyone but the hateful right now. But I’ve got the same question. That is a huge tube relative to the rest of the amp and I am curious about the power supply. Any brand? Do you know what tube that is.

Grado SR Series.

I’ve got those same marble finish edition!! My recommendation based on your photo: replace the headband pad and ear pads. The upgrade in comfort is significant!

edit: sorry I see this is already mentioned. But the recommendation stands, nevertheless.

If you post this request on head-fi.org I’m sure you will be able to find someone in Boston. Alternatively you can search for a local meet. Although I’m not sure if those kinds of things have waned since Covid.
