I thought that DAC technology had been around since CD players, around 1982. That is a long time.

Apple's iPhone 7 has a DAC built into a $20 adapter cable, surely Schiit' s DAC costing $900 can't be that much different to demand such a premium over Apple.

 
I worked making DACs for the medical instrumentation industry in the early 70's. Patents for early DACs date back to the late 1930's

One reason I haven't yet dropped the $100 on the iFi tubes is that everyone calls my '68 amperax more 'euphonic,' and i still find my HE-6s occasionally sibilant. I need all the euphony I can get.

I have seen a few people comment on the Mjolnir 2 pairing with the Senn 800 with generally favorable impressions.  Any recent impressions with the Mjolnir 2 and Senn 800S?  Positive or negative?  SS vs tube mode?  Any dacs you feel work well with these two?  
 
Thanks for your insights!

I have Sennheiser HD800's paired with the Mjolnir 2 with ifi tubes and Gungnir Multibit. I seriously enjoy the setup. I'm still trying to decide if I want to upgrade to a Ragnarok and Yggdrasil as I still haven't heard either of them but as for the pairing of the HD800 and MJ2, it really is incredible! All I can really say is upgrade the stock tubes to the ifi tubes. Stock, I didn't hear much extension in the treble and a general haziness in the high frequencies. The ifi tubes fixed that and added better separation and a wider soundstage. It's almost like everything was a little bit out of focus with the stock tubes and the ifi tubes brought everything into crystal clear perfection. The HD800 and Mjolnir 2 with the right tubes sound like a match made in heaven.
 
Sorry about the write up, I'm not much of a writer. If you have any questions or would like further clarification on something, don't hesitate to ask.

Hi blance44.  Thanks for your observations.  Can you confirm your cans?  800 or 800S?
 
Also, do you have any observations regarding your Senns and Mjolnir 2 in solid state?  I assume not as ideal vs the upgraded tubes but curious.
 
Thanks.

I have the Sennheiser HD800. 
 
I tried the LISST tubes for a very short amount of time. I felt as though the treble had more grain to it and the soundstage was a bit closer than with tubes. With those two things in mind, I didn't find them to be right for the HD800. I could see the LISST working well with planars like the Audeze lcd 2 but not anything as accurate and detailed as the HD800.

So when I plug my uerm into the se out I hear a faint hum on the right channel.  I cant hear it with hd800 or thx00 is this normal? I bought it off some one so I'd have to do a out of warranty repair.  I also swapped liist, and checked diffrent power outlets around the house with the same results from the right channel.  You cant hear the hum while music is playing, I asked a friend and he said its probably just too much power for the ciem  since my agd 1amp makes a low hum too.

If you are playing with tubes for Mjolnir 2 try Russian 6N23P-EV. They are among the best and do have very reasonable price, especially when compared to NOS E88CC from Telefunken or Siemens.

 

[blance44]

I've heard great things about those tubes! I'll have to give them a try some time.

Why is there a seam in the aluminum about an inch in on the bottom? It would be invisible except that I have it perpendicular to my desk and it sticks out. Would it be significantly more expensive without this?

From Jason's book, the Mjolnir/Gungnir chassis is longer than Bifrost/Asgard chassis. Because of this, the metal shop was unable to create a single piece chassis with the same U bend as their metal breaks are not capable of making that deep of a 45 degree bend. So, a compromise was made using a J shape for the top of the chassis and a flat plate for the bottom. This also made final assembly a bit easier when getting those LEDs lined up. Basically, it would be impossible to build the chassis as designed without this.

Can I use my chord mojo as the dac with the mjolnir 2? Are they compatible/good match for each other?

Yes they are compatible. I'm going to order the MJ2 real soon actually to amp my Mojo and Ether C/HD600. Just use a 3.5mm to dual RCA and you're good to go. Haven't seen any impressions of those two together though so also interested.

Any competent DAC is a good fit for the Mjolnir 2.  The more relevant question is if the Mjolnir 2 is a good match to your headphones.

Also if the Mojo is a "competent DAC" it lacks extension bothways, also soundstage on its own... Maybe it feeding line-out into an the Mjolnir 2 will add those things back kind of like a high gain switch on some amps. Remains to be seen though but I'm hopeful.
