Schiit Valhalla Tube Rolling thread.

Am I crazy for wanting to introduce a pre-amp to the chain?

Which preamp, which chain?

i dunno yet / before the valhalla

I thought that you might be thinking ‘Valhalla as preamp, Jotunheim as amp’ [keeping things in the Schiitdom and synthesising a Mjolnir II…]

valhalla 1 has no out, so would need to be a SAGA+ pre, or Asgard/Jot/Lyr

(or Rebel amp or Flux since I've been eyballing them as a solid state option, but they wouldnt match the schiitscape I have going on my desk)

I don't have a Valhalla anymore (I had the 1 years ago), but I follow this thread to get ideas for rolling my in Vali 2+. I have the opinion that the 6922/6DJ8/E88CC is a deeply flawed family of tubes. The treble is splashy and the bass is weak. Plus, many of them are extremely microphonic. You need a holy grail that costs three figures to get it right.

~ You have an opinion and everyone is entitled to my opinion (). Anyway, I cannot dismiss the entirety of a tube class. There are strong and weak members in each class.
~ The tubes that I have used, still use, or roll (in the Mjolnir II, the Valhalla II, and Woo Audio WA3) of the 6922 type include: 7308 Sylvania (green print), 7308 Amperex PQ (orange), CV2492 Brimar, E88CC Philips BEL (Holland design/made in Bangladesh)…
~ These, to my ears, are musically coherent and convincing, not bass-weak, not treble-splashy, not microphonic.

Valhalla II?:

Valhalla II?:

That is indeed a Valhalla 2 you have there

~ FYI, I have ordered a Flux Lab Acoustics FA-22…will definitely compare it to Valhalla II, Mjolnir II, Linear Tube Audio MZ3, Violectric V280…(it’s a tough job but bring it on! )

I mean that a Valhalla II, with its outs, could be a preamp.

That MZ3 tho...

if you ever plug one of them in before the valhalla as a pre stage, lemme know your thoughts

Could be but not an option (unless you're saying I should buy a second Valhalla so I can Val my Halla while my Valhalla Halvallas

Fair enough, blanket statements have problems.

But, if we're debating semantics, I'd say the 7308 isn't a 6DJ8/6922 because it has a slightly higher heater current, and that can change the sonics.

Also, I should clarify.....I generally dislike this family of tubes that aren't super expensive. The ones you can get for < $100 US are usually quite bland, flat, and a bit bright with splashy treble. The exotics from Europe tend to be better, so we agree there.

Any opinions on the 60's PQ 6922s made in the USA (white)? There seems to be a consensus that it's a pretty sweet tube.

I definitely like those...well balanced, good ambience retrieval, excellent detail, semi-sweet (in the chocolate sense) overall…I should have mentioned them…thank you for doing that.

For fun (?), ponder this as an exercise in pretzel logic (sorry, Steely Dan):

‘Generalisations are usually false’….

I just wanted to say I'm really glad I found this forum, I've really enjoyed learning more about this hobby from experienced folks such as yourselves. Keep those recommendations coming for tubes, and nobody tell my wife I'm buying more crap hahahah
