Maybe but honestly I think what I have currently with the MM may be enough, any more and it may start to get a bit harsh

Im at a bit of a loss here, this is not complaining by any means. I got the Bifrost 1, unpacked it turned it on and let it sit. My current set up is a Vahalla 2, Modi Multibit with the v2 firmware chip in it and a Eitr. VH sounded ok with the stock tubes, better with a set of NOS GE JAN 6922s...

There are those that would say a Valhalla is maybe the perfect amp for hd650s. If you really want neutral I had an Atom years ago and it was pretty much the definition of neutral to the point of being clinical and sucked all the fun out of music.

I know nothing of the jiterbug but 100 percent the Eitr makes a difference with my MMB. Ive had to take the Eitr out a couple times and every time its immediately noticeable.

I had to get one of the BF1s that were on closeout, Got the last one too. Looking forward to seeing how it sounds compared to my MMB/Eitr stack with the VH2. Also Schiit had a shipping label with tracking number created within 20 minutes and out the door an hour after my order. That's customer...

Im currently running a Valhalla 2 with a modi multibit and Eitr. Seems there are some Bifrost 1s with unison on the Schiit site. Is the BF1 a significant upgrade over the Modi Multibit or should I just go right for trying to find a used BF2?

I run mine with Senn HD6XXs and its wonderful.

with Unison cards too, I may have to give this a try. right now I have my Valhalla sitting here and then a Modi multibit stacked on top of a Eitr, which 100 percent makes a difference. The BF would significantly simplify my stack.

Oh man, I love my Valhalla 2 and I know you said upgrading it was going to be very challenging without basically completely redesigning the amp. So really looking forward what you have come up with. Any hints?? lol sorry, I know, had to ask. Really excited about this one. They found Bifrost...

Very interesting. The thing it the VH2 has been around so long because Jason has said multiple times that he really cant improve on the VH2 without basically completely overhauling the amp, making it bigger, more expensive and maybe even going away from the pure OTA tube amp setup which at that...

It will be interesting to see how some 5670s sound because I just put these Vokshod Rocket 6N1Ps, not sure if they are THE Vokshod rockets or not, and they actually sound really good with the stock back tubes. I tried the new backs, 6n6p, I got from Viva and it didn't sound as good. Put the...

Ok, I just got some adaptors from Garage 1217 which are way nicer than anything you can get on ebay and not much more expensive, so I'm gonna try them. So aside from the WE396As, which would legit cost more than I paid for the amp and I am just not going to do that. What are some relatively...

Ok. I was also going to try out some 12AT7s/ RFT ECC81 also someone in the rolling thread said they sounded good and were reasonable, but also need an adaptor. Were the 5670 the ones Mike recommended? I did a crapton of reading on tubes when I first got this amp, then I put the JANs in, it they...

I swapped the side of the tubes to validate that's its one of the tube causing static and they seem to fit better that way sot I think agian its the tube not the socket. Let me address the wobble too, they weren't loose, just I could move them more easily and more that I thought I should be...

How unmatched do they have to be before one would actually be able to hear it? this is all more or less curiosity and hypotheticals, I'm not trying to argue or anything like that, just kinda wondering how far out of whack can you really get before its stats to sound bad sort of thing.
