    Right now I'm using the Monoprice DJ Headphones. I'm going through a major upgrade and waiting on delivery of Massdrop/Sennheiser HD 6XX.

    I just ordered a new production Electro-Harmonix 6922 with balanced triodes. I'm not quite ready to spring for NOS. It'll be my first experience with tube rolling.

    This will be my first experience with tube rolling. It's a whole new world.

    Nice job, should be a decent tube, but seriously, give this thread a good read once or twice. Lot's of good info on all kinds of tubes!

    If you got the funds then go for it but you're looking to save a few bitcoins (LOL), a few hours of reading will help you nail down some killer tubes that shouldn't cost you much!

    But try and give the stock tube a go so you can reference back to it with newer tubes!

    The great thing about buying a Vali 2 now is that it is $20 cheaper than it was originally. That's like one free tube!

    Regarding those 5670 adapters: They are really inexpensive, and they take a LOOOOONG time to arrive (like 3-4 weeks). So if you ever plan to roll tubes outside the standard pin arrangement, go ahead and purchase the adapter ahead of time. If not, you'll be like I was: sitting there with a vintage 396a in hand having to wait weeks to plug it in and hear it!

    Regarding the vintage Western Electric 396a tubes: The first one I purchased was ugly, worn out, and highly unbalanced (30/36), but it was super cheap ($20 shipped) and still sounds better than the stock tube.

    Earlier in this thread Volly displayed his Frankentuber and it really took me by surprise. What does it do? What are the pros and cons? If I try this will I tingle with excitement?

    Am I already loosing my mind?

    Funny story:

    After months of searching for a bargain, I finally gave in and paid a ridiculous amount of money for a Western Electric JW 2C51 in top shape. It was shipped in an box that was comical large, and as I excitedly opened the package my five year-old asked “What is it Daddy?”

    Without much thought, I said, “It’s a vacuum tube.”

    After I retrieved the tiny white box from the ocean of packing peanuts and opened it up, a confused look came over his face. Then he said, “Daddy, I thought you said it was something for the vacuum cleaner?”

    He fully expected it to be an extension for the vacuum cleaner hose! :beyersmile:

    I recently purchased a Vali 2/Modi 2 Multibit combo from Schiit Audio and I've been putting it through its paces for the last 3 days. My set up is pretty basic:

    Computer -> USB (Audioquest Forest) -> Modi 2 -> RCA (PYST cables from Schiit) -> Vali 2 -> HD650

    I've tried the following tubes:

    Stock Tube: 6BZ7 Canada
    JJ Electronic E88CC
    Electro-Harmonix 6922

    The stock tube is OK, but underwhelming. Narrow soundstage, extension is meh, etc. It wasn't bad, and until I tried the other tubes, I was actually satisfied.

    JJ Electronic was better than the stock (better extension across mids, bass, without any fatiguing highs).

    The Electro-Harmonix is my favorite so far. Relatively airy presentation, separation, resolution, definition... it just has that je nais se quoi. It is hard for me to describe the difference - but the Electro-Harmonix just sounded like a more complete listening experience.

    I'll stick with it for a while before I try anything else.

    got my Vali 2 a few days ago...after reading all this thread (fantastic one) I am ready to roll (Yep, intended).

    I got two tubes coming, EH 6922 and one of those mysterious mitsus**ta of 7 volts.

    AND the adaptor for the (I expect glorious ) Shuguang Treasure CV181-Z. (I will machine the cover of the vali to make it big enough)

    soooo...as I said... ready to roll!
