Alright well I'll look into getting the Ragnarok from Schiit -- looks like it's 2-3 weeks before shipping out ATM unfortunately.
I'm already of course googling like mad --- but if anyone can offer their input on how Ragnarok/HE-6 sounds with metal and hard rock that'd be awesome. I've been posting in the "ultimate heapdhones for metal" thread and HE-6 is getting lots of praise, but also a few people seemed unsure Rag was a good choice.
ATM I am auditioning a LCD-2 with Lyr and my impressions are that it's just a bit too dark and lacks the bite that distorted guitar needs to sound good. At the same time, I am wary of ending up with something super bright as I've had some bad experiences with that (I absolutely loathe a thin/tinny sound)
I'm just posting in both threads as I'm not sure how much crossover there is.
Other thread for those curious:

If I were in your place, I would proceed slowly and carefully. Read as much relevant posts as you can and most important of all, listen to some of the recommended systems to get an actual experience. There are places in North Carolina that sell very nice amps that you could listen to.
From my experience--I usually do not recommend anything that I have not owned for at least several months--you have many nice choices:
Headphone amps that can (easily) drive the HE-6: HeadAmp GS-X Mk2 ($3,000 new); Bakoon HPA-21 ($3,000 new); Apex Peak/Volcano ($2,200 new); Woo WA5 ($4,500-$6,500 new depending on parts and tubes). If you buy them second-hand, the savings are substantial.
Update: the Ray Samuels Dark Star and Hifiman's own EF-6 amps can also drive the HE-6 easily.
Good-sounding Speaker Amps that can drive the HE-6: First Watt M2 and J2 ($2,500-$3,500); Pass Aleph 3 ($1,200 used and restored); Krell KAV 300i or 400xi (integrated amps with volume control; $900-$1,400 used); Conrad-Johnson MV75 (tube; $1,200-$1,500 used); BAT VK75SE (tube; $2,000-$3,000 used); Sophia Electric Baby Amplifier (tube; $1,000 new). Harmon Kardon HK770 or HK870 ($100-$200 used + $500 restored and upgraded).
You will need an adaptor with these speaker amps (from Hifiman or other places), especially with tube amps (about 8-10 ohms in parallel and 15-30 ohms in series) to protect the tube amps against unstable load and the HE-6 against too much power. You also need a DAC with volume adjustment (not necessary with integrated amps).
If I were you, I would get the Woo WA5 or the GS-X Mk2 that will also sound great with just about any other cans--and you will buy other cans if you keep reading these posts--and forget about the headaches with speaker amps, unless of course you also want an amp for your speakers.
