The mk2 was fixed after I hounded Massdrop and Aune to nearly no end. They were trying to claim it could do 32 bit and DSD from the way they programmed it, but that was simply impossible from their combination of USB chipset and DAC. I think their software engineer was a little over-zealous.
No. The Mk-2 will only get you to 24/96. I repaired my T1 and the distributor installed a Mk-2 dac board in it. I found that it's still limited to 24/96 like the previous version.

That's cool! I don't plan on asking because I don't really have any headphones suitable for portable listening. I know a lot of portable junkies like the IEM's, and closed back headphones. Damn does that B1 look sharp though, Aune. Nice work!
Just ordered one. Going to try out my Grado Ps1000's with it, as the only other amp I have is an Oppo Ha2, and I'd like to have a stationary amp at home. Also, I want to try running these babies through some tubes. Now, someone might think "what a cheap amp for those phones!", but I got a feeling I won't be disappointed
Actually were surprised I could find these items, in particular at such reasonable prices, here in Norway.
Update: Just picked up and running. Analogue line input directly from my Iphone 6. Its GREAT! Actually much better than I expected, and does wonderful things to my PS1000'S. Controls the bass and the very high level of high frequency response very well. Everything sounds very balanced and nice. It does narrow the sound stage a bit though, but I'm ok with that. Listening to Imogen Heap now while smiling. Great to know I dont NEED to use the DAC for it to sound good.
Its set to 0db gain and has more than enough power for these low impedance phones. No hiss or artifacts at max levels while connected. Very, very satisfied here.
That sure sounds like you mean from iphone into it using the rca analog jacks inputs. Which is NOT what you want to be doing it bypasses the tube dac and really makes using it totally pointless. You might not NEED to be using it right, but you haven't heard anything yet. Just wait till you start using it right and get a nice upgraded tube. Magic Happens.

I debated that with someone in another thread here. Are you 100% this is the case with the mkII? This is what I wrote in that thread:
"Hmm. But why does the tube light up when running in line in mode? On this page, under 2), it says that it is a high quality "tube amplifier", while under 1) it says its a tube usb dac: http://en.auneaudio.com/html/en_products/NewDesign/T-Series/154_20.html"
With those 1 and 2 alternatives, I feel they differantiate between two seperate functions.
Also, its a bit strange if the tubes dont work when set to line, as the sound suddenly were messed up for a moment, as the tube were heating up for the first time. It would be rather stupid to fire up the tube as well, when running on line, if its not used. I dont have a clue though. I guess you know what you are talking about
Anyways, I wouldn't say its "pointless", considering it sounds awesome on the line setting, but it is a temporary solution anyways (my life is in boxes due to moving these days).
