Very nice pick doc! Here's its more recent iteration.

I have a tube amp (Antique Sound Labs) but it needs some attention (new input block rca jacks) before I can use it again. Wish the folks at Antique Sound Labs would support their great sounding products.

I think the new Denon headphones are comfortable but I haven't had them on long enough to report.

Enjoy the Music. Trust your ears. Laugh at Folks Who Claim to Know it All.
