To give an update in case anyone else has the problem, changing the tube fixed it. 

Unfortunately I don't have any others to test with. 

Hey all, so my V3 seems to be having some issue. It's un-modded, had it for a few years now, and suddenly I came home and turned it on and I only get sound out of my left ear. I've confirmed it's an issue with the amp (tried other headphones/sources). Did a bit of googling but I couldn't find...

Yeah, already checked there and ebay. Just wanted to know if anyone here could recommend something. 

Can anyone recommend a place to get replacement cables from? My 3M cable is going bad and I don't want to use the 6M for daily use. Not really into fancy snake-oil stuff, just a decent Mini XLR -> 3.5mm or 1/4 inch.

I tried both the Valhalla 2 and the Lyr 2 at T.H.E. Show Newport, they didn't have any Q701s to audition them with though unfortunately. 

    I assumed it was already drawn.

Wow, guess I'll get there a bit earlier tomorrow. 

I can't wait to try that thing, I hope it sounds much better than it looks. 

Well shoot, I've heard that the S.E.X. is a better fit for them. Looks like I'll have to go that route, though it's quite a bit more expensive. 

This'll be my first headphone event, excited to attend!

Hey all, I've been planning on building a Bottlehead Crack for a little while now but I decided to do some more research and found many saying that the Q701 and the Crack aren't a good pair. Anyone have any personal experience with the combo?

Already had them bass modded, I was hoping they wouldn't notice if I sent it back :)
