Haven’t rolled the FV yet but the MZ3 forum folks swear by Brimars and MELZs in the MZ3.Did you get to roll any tubes with either amp? I just realized I’ve had the FV for weeks and haven’t rolled any of the tubes I have

I'm glad we had this group conversation, and you got (made) another chance to try them. Some of the rune markings on the Schiit gear are fairly inscrutable. Hope you enjoy the Folkvangr.Went back to the Schiit store yesterday and spend some time listening to the Folkvangr and Valhalla. The volume issue with the Folkvangr was my fault, I switching the impedance multiplier switch instead of the gain switch. Volume problem solved with the HD650’s. I returned the Valhalla and placed my order for the Folkvangr. The wait begins. Attached are pictures of the Schiit store. I highly recommend you visit if you are in SOCAL. Just over 130 miles one-way for me and it was well worth the drive.

Well, I've just taken delivery of my Folkvangr. Unpacked it, put the tubes in, set it in the main rack, and got it connected. Turned it on, let it warm up for a few minutes, and then I listened to "Roundabout" by Yes via through the Yggdrasil A2, just to make sure things are working properly. (Wow, Squire's bass slams in my HD800s.) I'll put on a LP after dinner to check the other input and see how it sounds with vinyl.
I'll need some burn-in time and several days to fully evaluate it, but my first impression of it is delight.

I've got my package today. Testing with HD650. The sound is so holographic and engaging even with stock tubes. Pure love.
How are the HD8xx on the Folkvangr? Thinking of picking up a pair or an 800s. Or possibly a HD650 just for nostalgia.
Ordered this past Saturday and received notification the Folkvangr will be ready for pickup at the Schiit store this Thursday. Too bad my first day off from work is Saturday. First order of business this Saturday is a trip to the Schiit store for pickup.

Has anyone tried 600ohm headphones yet? The official specs only cite 300 ohms for the power rating. I assume it would be a bit more than the 1.2 watts cited.

Less, probably by half. We can probably assume the 1.2 WRMS at 300R is the maximum voltage swing of 19 VRMS. This is because based on the lower impedance power levels, it's not current limited. So the same voltage swing at 600R is 0.6 WRMS.

I tried the dt990s 600ohm on my Folkvangr. Best I’ve heard them…great bass slam, good clarity and holographic staging. Had to kick it into high gain. Really like them with electronic ... Infected Mushroom , Smilk, Spoonbill and the like are great on the BeyersHas anyone tried 600ohm headphones yet? The official specs only cite 300 ohms for the power rating.

Oddly I didn't love the pairing, but I don't think I liked those on any amp. Thought about the tape mod but decided to just return.How are the HD8xx on the Folkvangr? Thinking of picking up a pair or an 800s. Or possibly a HD650 just for nostalgia.
Everybody has their own personal preference. I liked the 800s, but not as much as the Clear or the VC.Oddly I didn't love the pairing, but I don't think I liked those on any amp. Thought about the tape mod but decided to just return.
IME the 800s seems to sound best with a higher impedance output than the FV. On my Woo using the high impedance tap it really sings.

I thought OTL/OCL had an inverse effect with resistance? e.g. 32 ohms is only 300mW without the impedance multiplier enabled.Less, probably by half.

There's a voltage limit, and a current limit. Hit either one, and you are at your max power.
Based on the 32R power, I calculate the amp can put out 96 mARMS (at 3.1 VRMS). Based on the 300R power, I calculate the amp can put out 19 VRMS (at 63 mARMS).
So those are your two limits, 96 mARMS and 19 VRMS. Higher impedance runs less current, so pop 19V and 600R into an ohms law calculator, 0.6W. Now, those specs might not be hard limits, because they are max power at 10% THD, and that might differ with different impedances. But it's still a fairly safe bet.
I have absolutely no idea what happens with the impedance multiplier turned on.....

drop 8xx > drop 6xx BUT brand new 6xx, early days, we'll see. Love the 8xx with it though. 8xx an be a bit much with music that has a lot of hi frequency energy.How are the HD8xx on the Folkvangr? Thinking of picking up a pair or an 800s. Or possibly a HD650 just for nostalgia.
The 'same date - gold grid' set of 6n6p's haven't blown my mind with any warm fuzzies over the mixed decade/brand stock set.
Mullard ecc84 up front (with adapter) may be adding a little warm mid bass hump? Or just music with warm bass and wishful thinking?
