The FocusPad-A are recommended for the HE-6SE.
You are in luck. Jot 2 came out. I heard an early prototype of Jot 2 (as did @ChaChaRealSmooth and @penguins). Damn that thing rocked and slammed with authority with HE-5 / HE-6. Only problem with that proto is that Vali 2+ was sounded way more nuanced. Obviously can't have a more expensive product be worse right? I kept telling Jason to put Continuity (Aegir output stage) in there.
The release of Jot 2 so soon with the Aegir output stage was unexpected. Jason only lets me listen to the shitty sounding early prototypes and have me tell him it's not good enough before he gets them right. The final production Jot 2 amp should fit your planar needs. "Only" 6W into 32-ohms, but it's more than this really. I have not heard it yet, but I have an idea. I'll try to get one and review, but this will take at least a week and I will be moving from CA to TX this weekend.
FWIW - Just looked at specs. 4W into 50ohm (HE6/se happens to be 50ohm).
To answer the original question of this thread: If I didn't already have the Cavalli Liquid Crimson already, I would have bought this immediately this morning after seeing purrin's status update and the specs + schiit's "aegir stuff" in a jot format. My only concern in my own set up would be that this will probably get quite hot and dissipate a lot of heat in case that's also a concern in your own setup.
Spoiler: Extraneous thoughts on power output for HE6 family
I know some "conventional" knowledge out there recommends at least 5W into 50ohm for the HE6 family and maybe more if you have mods that really decrease sensitivity for sufficient umph (summarized as slam, heft, fullness to sound, not limp, not tinny, etc.) and better / not undershot transients. However, without knowing what I was listening to at the time - yes, this prototype delivered "enough" power. Cannot comment on how much "overhead" is available or not for said mods as I don't know what mods were done on the HE6 (2 different ones) that I heard that day or how a stock HE6 would sound on this amp, etc.
I say "enough" even w/o knowing what the prototype was at the time as I did try HE6/se (and for that matter LCD3 and EFO1.1) with several different headphone amps after in search of a good amp for planar headphones and many did not have "enough". Not that these were bad amps - I did it knowing many only had 1-2W at 50ohm (i.e. not enough), some had ~3-4W at 50ohm (half were still slightly under powered, probably depending on amp topologies, etc), the 2 others I did listen to at 5W or more were enough.
Oh Gawd help me, ordered... "The results? Jotunheim 2 now does 7.2W RMS into 32 ohms at 1% THD, up from 5W on the Jotunheim. (We rate it a bit less at 6W RMS, because that's how we do things around here.)"
Hmm, I kinda do want an amp that runs hot to help keep my feet warm in my home office... (it gets cold up here in maple syrup land)
which part of maple syrup land? It was 3 this morning in vermont....
-20 celcius in Montreal today
It's actually strangely warm today as the weather is just below freezing (December heatwave, wtf?). We were around -25 with the windchill a couple days ago which is more the norm. Maybe a couple days of -40 by the time we get to mid January.
So, we think the jot2 can power the he6se?
how would it compare to the lyr or the mjolnir?
and is multibit worth it for a one box solution?
1. We already established that it can.
2. You should know by now that small tube amps are going to underpower the HE-6.
3. That depends on your DAC preference.
You've reached a point where trying some of this gear is the answer to all your questions.
I agree with your sentiment here 100%. You have to dip your toe in, and reading impressions is no substitute for forming your own. That said, with respect to item 2, I don't see any reason why Lyr 3 and Mjolnir couldn't power the HE-6 SE. Lyr 3 is rated at 4 W per channel into 50 Ω, the same as Jot 2. It's a powerful hybrid. And Mjolnir has a reputation for kicking harder than any other amp Schiit has made. It's rated at 5 Wpc into 50 Ω, so 25% more headroom than either Jot 2 or Lyr 3. I think there is a distinction between amp requirements for HE-6 (old school) and the HE-6 SE re-release. For HE-6, it seems like power amps are still the standard, and I don't think Jot 2 is powerful enough to change that. But for the HE-6 SE, it's probably a matter of taste between Lyr 3, Mjolnir, and Jot 2. Cool that Jot 2 offers so much for so little, and nice to see the switchable pre-outs.
If the loaner tour happens, I'd be happy to see if the Jot 2 can power my Code-6 well. Personally of the opinion here that more speculation on this front is just that; speculation and noise.
For reference, my current go-to amp for Code-6 is the one-off EC Ultralinear, which definitely has the juice to power those (it can easily power efficient speakers).
I have a Lyr3 w/multibit (and currently a LISST "tube"). It's fine with most headphones, and it gets "loud" enough with the HE-6 but doesn't satisfy me. Then again, I'm a nutjob with monoblocks for his HE-6 so pay no attention to the man behind the curtain because I threw out common sense years ago for the HE-6.
It is funny you mention the JLH amp, as I too feel it does a fantastic job on the 6se, inefficient planars and 300 ohm dynamics. Sure when used as a headamp, you are likely only getting a few watts into the 6se, but it is all Class A goodness! I actually sold mine to go in another direction, regretted it, and picked up another on 11:11 from AE for $180 shipped from China. And you know what, the new unit is dead silent! My first one had a slight buzz in one channel at higher volumes. I highly recommend a preamp or DAC with volume control to make the JLH much more versatile as a headphone amp, as the gain is high. Unit variance and the DIY nature of the amp does make purchasing one a gamble, but well worth it if you get a good one!
Based on the early proto Jot 2 with only Nexus and no Continuity, the answer is yes. I am certain that @zerodeefex is purchasing a production for the CO crew. I'm on board to get one, but only at the beginning of next year. You will have to wait for reports back to be certain. Power ratings have little to do with it. Some amps such as JLH '69 (which is maybe 2.5 W into 32-ohms) do well with HE-6, others that theoretically should do well such as Jot 1, don't. I'd say only a handful of headamps I've heard did OK with the HE-6. Note that HE6SE is a bit easier to drive than the OG HE-6.
And there is no correlation to some other stat?
it’s interesting to me that ohms law doesn’t provide concrete guidance for these headphones.
I am trying to wrap my brain around that. The sp200 does ok with them. I am trying other things just to see if power is really the issue.
the idsd micro distorts in the bass at high volume.
the dx3 is clearly underpowered and can’t bring the volume.
it just seems odd. I am going to try giving them up to 16W into 50 ohms. See what happens.
Well, fun update.
I got the a90/d90 and speaker amp in to try with the he6se.
The he6se right driver died while a/b testing topping against the speaker amp. I only got about 20 minutes of listening on the speaker amp. (It died while connected to the a90).
I was surprised about how much of a difference it made. I don't know if it was at "sold me it's worth it" level, but it really was far cleaner, more dynamic sound coming out of these things. I wouldn't call it night and day, but definitely a noticeable improvement across the board.
On the a90/d90 side: It is very clean. But not worth the price. Nothing about it said "I am worth $1200" to me. They are going back.
Now that the he6se are dead, everything is going back. And I am moving on to the next leg of this journey.
I expect that to be focal or ZMF. Will start a thread around that after I read everything I can on here about them.
Merry Christmas everyone!
