What are you using for a DAC Reddog?
I am using a old school pioneer Reciever that has a 192/24bit dac. I hope to get the Gungnir dac next year. Although the irrational audiophile beast within me demands I save up for the Yggdrasil lol.

Reasessment of the Alpha Dogs, I really like them them but they do need some serious EQ adjustments to my ears.
Here's my curve for Flamenco Sketches, outstanding!
Whoever said they were bright, not to my ears particularly with Jazz & Samba
I'm new to this thread as I'm considering a Mjolnir to drive my LCD-X and XC.
............... It is a big step up, potentially in part since the output impedance of the Mjolnir, 1.5 ohm, is just too high for the LCD-X with its impedance of only 20 Ohm. I know, recommending a more than twice as expensive amp isn't all that useful/informative...................................
Stefan,
Glad you are enjoying your Ragnarok. However, I don't understand the linking of the output impedance of the Mjolnir to poorer performance of the LCD-X. The Audeze are quite flat in their impedance vs. frequency, so 1.5 ohms should have almost no effect on sound quality or frequency response. Please explain. Thanks!
I'm no EE and new to audio, so I may be mistaken, but my understanding that frequency dependent HF impedance and hence equalization problems isn't the only way output affects sound. Additionally, low damping ratios also lead to lack of bass control and 'muddy bass'. I do think I hear that in the difference between the Rag and the Mjolnir...although it could be due to something else, the audible difference it there. BTW, Purrin makes the same claim elsewhere, both for what you can hear and the cause, so I may be too influenced by that (but do blame him, if this is wrong about the cause).
I can't make up my mind if I want to sell my BA or not. If I do, I will need a low cost high performance replacement. (I mostly listen to my electrostatics now.) Also, a solid-state reference quality amp is always nice to have on hand for my measurements and subjective impressions of the plethora of overpriced crappy headphones which the big companies seem to be churning out these days.
It also matters because I know for a fact that there a lot of lurkers who trust my opinion (I'm sure there are also quite a few who think I'm full of crap), mainly because I'm not afraid to say that a lot the stuff which tends to be highlighted on HF is crap, so if I'm tempted to buy something myself, that may actually mean something to someone who's seriously considering the Mjolnir.
Thanks, all, for your information.
The HDVA doesn't lack power. It drives the HD800 very well from the Uber Bifrost (unbalanced) feed from a Macbook pro. Volume dot at 10:00 is plenty of dB.
The HDVA also drives the LCD-X to loud levels, but the sound quality is poor. Everything sounds muddy (even the treble). I was suspecting this may be caused by the output impedance of the HDVA which is 16 ohms. In comparison, my Asgard 2 with output impedance of <2 ohms can drive the X with clear sound quality.
The X specs recommend 1-4W of input power. The Asgard delivers 1W into 32 ohms. The Mjolnir delivers 8W into 32 ohms. Both these amps have output impedance of 1.5-2.0 ohms. My conclusion from reading these specs is the Mjolnir should drive the X more fully with similar sound quality. Does this seem correct ?
I agree the Rag is completely different with 15W into 32 ohms and only 0.03 ohms of output impedance.
Thanks -
