Definitely interested as well. I'm in North Oakland. I don't own a car but often rent a Zipcar if need be. What I can bring to the party includes a Schiit Valhalla 2, Bifrost 4490 (soon to be upgraded to Multibit), Senn 580 Cardas, Senn 600 Blue Dragon, Grado RS1i Black Dragon, and Audeze iSINE20.

These are exactly what I got but your preamp tubes are from 1973, not 1976 like mine. Seems like Schiit is sitting on a healthy supply of nice NOS tubes to ship out with their Valhallas. Makes me feel good about buying into the brand. Seemingly against the typical tide they are shipping better...

Das Keyboard 4C Ultimate, Greetech Brown switches. I love it! I have their full-size 4 Ultimate with Cherry Browns at the office.

I've used TubeDepot and TheTubeStore over the years for my music gear. I've rolled a ton of tubes new and NOS through my James Demeter VTBP-201s bass preamp and I liked the JJ gold pins (7025) in there. The Sovtek LPS was also a nice one. The set that's in there now are from RAM Labs which are...

That's what I thought! I did my due diligence researching these particular Russian tubes that I didn't know much about and here I got a decent set from them to start with. Thank you Schiit Audio. Their value is not lost on me. Still gonna get some gold JJs and some 6N23P Reflectors.

Tube vendors aside...   I just received my Valhalla 2 (and Bifrost/HD 600/Blue Dragon V3) earlier this week and have been putting some hours on them. I'm not sure what used to come with the Valhalla 2 but what I just received are mid-70s NOS Russian. Preamp tubes are Voshkod Rocket 6N1P...

Well there's your problem right there. Nothing against the brave souls that work retail (like I used to) but GC is the last place I would go for tubes.

Here's my current head-fi station as of a few minutes ago. Still breaking in a new Bifrost, Valhalla 2, HD 600, and a Blue Dragon V3 cable! Interconnect is Tara Labs RSC Prime and power cable on Valhalla is Tara Labs Prism AC Special (found I like it there the best). All running off a Furman...

Newly-arrived Dirty Loops CD ripped ALAC   and a re-buy on an album that was lost long ago and only survived in my collection in 320 MP3, also re-ripped in ALAC, that features my heroes Anthony Jackson on contrabass guitar and Vinnie Colaiuta on drums.      

Just got a new Bifrost and Valhalla 2 and am burning them in and putting them through their paces with some dense selections at Redbook and above.                    

I wanted to chime in and give my love for the 600s. For nearly 20 years I used 580s as my reference recording and playback headphone, eventually upgrading to a Cardas Fat Pipe. Wanting to get another Senn HD in rotation about five years ago, I auditioned both the 600 and 650 and chose the 600s...

Checking out organs and amazing acoustic spaces with the new SR80s.        

Breaking in my new Grado SR80e's with, among other things, some Steve Tibbetts "Exploded View" at 24/96 through Audirvana+ and an Audioengine D1. Trying the S and L pads and with both, they sound fantastic! Way more sensitive than my modded HD580s and expectedly, way more up front!
