I have a couple of the same CV4079 adapters from Xuling and agree that they are scary tight. I was so afraid a tube would shatter that I wore gloves the first time. As LobalWarming said, they will loosen somewhat over time. He's right that you want to rock the tube (slightly) from side to side...

I agree that the NU 6F8G is a great sounding tube. I just think my NU 6C8G sounds equally good at half the price and was wondering if more discerning listeners heard any difference. (My ears are 70 years old.) I had a couple of TS BGRP 6F8Gs in the past, but the tinking sound they made when they...

I have a National Union 6F8G and an NU 6C8G, and they sound identical to me even though they have different amplification factors (20 vs 36). Do any of you hear a difference between the 6F8G and the 6C8G? I'm curious because I also have a TS 6C8G, which I really like, and was wondering if it's...

Oh, you're right! They are both OG cards.

Thought I should mention that the green card in that pair of photos is not a newer version of the OG card after all. It's a 2/64. https://www.head-fi.org/threads/schiit-audio-bifrost-2.914084/post-17570818 Probably does contribute to the more linear sound of the 2/64 card. ;-)

I have an H5 Miflex for my ZMFs and was using a Garage1217 Solstice for my Hifiman Arya planars, but after building LobalWarming's Traffo-House I've retired the Solstice. The Ayra is stunningly good with the H5 + Traffo-House. Kinda wish someone else would build one and chime in here... They're...

I think a lot depends on your signal chain, and the type of music you listen to can make a difference, too. I listen to a lot of jazz and acoustic music, and I like my transients to be more rounded and then linger a bit, but people who like EDM would probably prefer the sharper transients that...

I have both the OG and 2/64 Bifrost 2 cards, and I usually use the OG card. From time to time I start thinking it's a little too laid back and roll in the 2/64 card, but after a day or two I always go back to the OG card. I can listen to it for hours, whereas I find the 2/64 a bit fatiguing...

I continue to be delighted that I can use my Hifiman Arya with the H5 using LobalWarming's traffo-house(r). I also have a ZMF Atrium, but I find myself using the Arya more - that's how good it sounds. If you decide to build a traffo-house, here's a few notes that LobalWarming sent me: • Make...

Those of you who follow this thread, or the Reference 6SN7 or Schiit Happened threads, among others, have probably seen posts by Globalwarming. He has been offering up wry comments and sage advice about cap and tube rolling for some time, and I consider him a friend and mentor. Well, not long...

Just want to thank theveterans for this - I use Audirvana on my Mac Mini and I switched on "Upsampling" to "2X Only" using r8brain, and when used with the Bifrost's MCB it took a bit of the bite off the leading edge of transients. Now they sound just a hair more rounded. It's subtle, but it's...

LALALALA! I'm not listening and I can't hear you!

I actually had two Ayras - v1 and then v2. I haven't had chance to try the Stealth. I'm seriously tempted to get an Arya Organic to use with my little hybrid tube amp (a Garage1217 Solstice). I got it wrong - the Feliks echo mk2 is indeed an OTL, as is the Eufonika H5. As far as I know, the...

Sent this in a PM to carballada, but I may as well post it here, too. It basically repeats what Lobal and others have said: I had an Arya when I bought my H5, but unfortunately it was not a good pairing - the Ayra sounded anemic and thin. I wound up selling my beloved Ayra (I still miss it) and...

Thanks to Tim for a nice headphone at a good price! The extra cables was icing on the cake.

I agree they look great. Just what I need to complement my Atriums. PM'd.

Bifrost 2 (both OG and 2/64) is an R2R DAC...

No longer available

Nick - I had some hum when I first got my Eufonika H5 Miflex. Solved it by plugging the H5 power cord into its own AC socket, separate and away from all my other AC adapters and crap, which are plugged into a power strip connected to another AC outlet on another wall of the room. Not saying...

zexk, I would use the same caps but if I remove them from the OG card, the leads will be really short and hard to work with, and also I'd rather risk ruining one card than both. Anyway, I got six Nichicon Fine Golds for $13 on Amazon. I'll let you all know how it affects the sound in a few...

Thanks - good to know. Warmth is what was missing. And timbre. Looking for Nichicon caps right now, and I can replace them for less than I'd lose by selling the 2/64 card. Just can't decide between Nichicon ES Muse or Fine Gold, or Nippon Chemi-Con KZG...

Hmm. I've withdrawn the listing for my Bifrost 2/64 upgrade card. zexk is right, and has got me thinking I might as well void my warranty and replace the caps with Nichicon. I've been cap-swapping in my OTL amp recently, so why not do the DAC, too? Just gotta get up outta this recliner...
