Schiit Mjolnir 2 Listening Impressions

I see nobody has mentioned Telefunken PCC88 / 7DJ8. Got a pair from upscale because of the intriguing description:
 
  Telefunken PCC88/7DJ8 - This is a 7 volt version of the super-expensive, impossible to find 6DJ8. Smooth highs that maintain extension without being bright, with great detail and texture in the mids.
7DJ8/PCC88 are a great choice.  They are absolutely compatible with virtually any product that uses 6922 and 6DJ8   Whether it's an amp, preamp, CD player, whatever.   You still need to pick a good one of course.  And one that meets your sonic requiremements.  And Upscale Audio doesn't sell any sucky ones.  But understand this:  You are in essence getting tasty stuff for half what you would pay if they were labeled 6DJ8 instead of 7DJ8.  They will operate the same.  Trust Uncle Kevvy on this one. 

 
I actually like them a lot with MJ2 and HD800. Sound amazing.

Awesome.   They will sound even better with some run time.

Curious, how do you guys store your tubes?

Also I know there's another brand other than the socket savers I can get but what are they called? I'm always having a hard time removing the tubes I have.

Received a package of Schiit yesterday and I have to say Schiit never looked or sounded better. I'm still in the break-in phase, but my initial impressions are very positive. Right out of the box I noticed better imaging, more air between the instruments, more bass control and a wider sound stage. This is with the lisst tubes in place. The brushed aluminum is nice but, my oh my does, it scratches easily. There's also some kind of film on the aluminum which creates an uneven look when you touch the chassis and compare to an area that has not been touched. 
 
I've  been checking out audiophile tubes (top 17) and with the asking prices, I'm going to assume these are the equivalent of audiophile crack. I suppose there are deals out there on ebay and I've been perusing the tube section. In the meantime I'm going to enjoy my new amp and figure out what I want in the way of sq, but generally speaking I don't think I want to alter the sound too much, but rather enhance and dig deeper into the recordings. 
 
This is going to be fun and this site has been an unbelievable source of information. Oh. and yes this amp produces heat, but I'm ok since it's snowing here in the mile high city. Cheers, Bob

I store mine in a pelican case with pelican desiccant (check my profile for exact model). I also use the paper tube boxes for my NOS that don't come with boxes. Also even with socket savers, it can be a pain to tube roll. I recommend something like this:

Someone here recommended a trick to remove tubes and it works like a charm.  Take a small pc.  of cellophane and wrap around the tube.  The cellophane grips the tube and also your fingers.    With the socket savers I don't need to do that anymore but it did come in handy.

Back on the Lyr tube rolling thread there were comparisons of the various socket savers and risers.  I would caution to stay away from the cheap Chinese ebay versions - you can tells these by the screw in the middle.
 
Tubemonger's risers are the best - I have had both kinds and prefer these.  I have tube rolled so much I'm on my third pair - they will wear out with enough use (hundreds of swaps).

I have the tube monger ones as well and love them.   He was looking for a cheaper version and I reluctantly provided a answer lol.

Some folks on the Lyr said the Chinese Ebay ones detracted from the sound - in all my testing on the tubermonger ones I could not tell any difference plus or minus with theirs.  Which is a good thing I guess.

OK. Is this a crazy plan? Buy the MJOLNIR 2, and use it two months (with the Musical Fidelty DAC) until I can afford the GUNGNIR? Headphones in use HD-650, HE-560, and HE-400i. Eventually getting a HD-800s. Source, AIFF files via iMac.

Welcome to the exciting world of brushed aluminum, where every touch, wipe, and brush against it adds new unique, never to be removed "detail" to it. I remember when brushed aluminum computer cases were the rage, holy crap try working on or moving an aluminum paneled computer and not jacking up the finish.

Does look amazing though...

That's a great plan, man.
 
Sell the HE400i's, mod your HD650's and EQ/mod the HD800's.
 
And either stick with LISST if you want neutral tonality, or get some NOS tubes to maximize the pleasure listening experience.
 
Then that's it, leave Head-Fi and enjoy the audio.
