    Not to spoil your fun or anything, but the Vali 2 may not be the best match for your 600 ohm Beyers. At that impedance, you're only getting 140 milliwatts of power, and while the DT880's are reasonably sensitive, I wouldn't refer to them as highly sensitive. But if you like the sound you're getting that's really all that matters. Since you're giving the Vali you have to your son (what a Dad!), you might take a look at the Valhalla for yourself. More money, but 2.5x the power into a 600 ohm headphone.

    For adapters, if you're in the EU you might want to PM fellow HeadFi'er @Deyan . He does some very nice work and may even cost you less (delivered) than buying from China.

    thanks for the replys everyone. there seems to be three popular places here in the uk to get valves, HotRox, Watford and Langrex well thats what i have found no doubt there are a lot more.

    is it necessary to have the valve triodes matched? as i seem to think i read that the Vali 2 has auto biasing. it only seems to be Watford that have matching as an option and only on the Tung-sol 6SN7GTB.

    i'll give Deyan a PM at some point soon about an adaptor. i'm thinking of taking the case down to the workshop and putting the alloy top in the milling machine to enlarge the hole so the valve dont stick out as much. if push come to shove i could even make up a complete new top.

    if the Vali 2 can handle the DT880 600's then it will handle the superlux HD-330 that the son uses. those cans are an absolute audio bargain with the right earpads and a bit of dampening in the cups.

    i pretty much gave up on hifi years ago in favour of AV. the system i'm cobbling together for the son is bits i have lying around and if he looks after the systemdek i might even give him the PT-TOO.

    I have never found matching to be be a problem. I haven't bothered to order a matched 6sn7 yet.

    1st of all -- WELCOME!!

    2nd of all -- KUDOS on reading this thread in its entirety.

    Depending on where you in in the galaxy, you may or may not be able to get them. The "new production" Brimars are not available in the US, as far as I know (or is that Mullard?). Anyhow -- I've not heard anything about them, but if you want new production tubes I suggest JJ Electronic as a few here have had good things to say and they are pretty darn cheap. Doesn't hurt that they are Schiit's new tube of choice in their 6SN7-based amps (replaced new production Tungsol). :wink:

    Nope, shipping to the US not currently available...which is of major benefit to my wallet. LOL!

    They have US states populated in the drop-down menu for shipping estimates, so it appears they are getting set up for it though.

    And welcome to @bibbs !

    Welcome to the thread, eh. While I'm mainly using my Valhalla 2 and (newly purchased) Asgard2-BifrostMB pairing, my mighty Vali 2 is kept close on hand. :ksc75smile:

    Wow, you really are a Schiit head. :darthsmile:

    Have you ever looked at or considered the Lyr 3? Or, do you feel your needs are all covered and the Lyr 3 would bring nothing new to the party for you?

    Curious to hear from the true believers.

    PS: I LOVE my Loki and really like my Vali 2, so I am also a fan.

    Yep -- Russian tubes. The cup getter holder is a dead give-away. The only thing these share with NOS Brimar tubes is the name. :frowning2:

    I used to think Russian tubes were junk until I got a hold of Fotons and Melz. :astonished:

    Well, practically anything is better than a Sovtek. :D
    True, but I suspect the new production Brimars are closer to EH than Foton or Melz. :wink:

    You're probably right!! :D
