    Atomicbob, did you happen to try measuring what difference (if any) Regen makes on Gungnir MB jitter/digital performance?

    The corporate research gig has me booked for most of today. I have a day off tomorrow and will see if it is the dScope script automatically changing some level or if there is a difference between the Gungnir MB digital inputs. There is also the possibility that the USB to SPDIF DDC (Reflink) introduced a change in the data.

    Thank-you. Will be included in the testing tomorrow.

    Not yet. Will try to work this in with other requests.

    wasn't reading properly but thats still a mighty find square wave with little overshoot and virtually no rounding. Impulse response and maybe even 16 bit -90dbFS would be nice to see.

    The generator for the Balanced 1 KHz -90 dBFS USB sine was inadvertently set to -84 dBFS for that one measurement. The correct graph can be seen in the 2nd post, first picture, in this thread:

    Tests I intended to run today are delayed one week due to an unfortunate medical emergency at 0200 today.

    Hope things are better. Thanks for finding the reason for the "which one these things is not like the other?"

    Thank-you all for the kind thoughts. Worst is over, but like earthquakes, there are after shocks. Holding steady at the moment. Good news is that I can spend a lot of time on recreational listening, as long as it is calming music.

    I noticed you accidentally attached a repeat of the charts from part A. Do you happen to have the part B charts? I'm considering this DAC and would love to see them for SE.

    I own a Gungnir MB and I can tell you it’s a fantastic sounding DAC and certainly worth the price. There’s a possibility that there will be an upgrade soon to an “Analog 2” Model. I didn’t want to wait anymore so I ordered mine a couple weeks ago. I’ve had it for almost a week and I’m very satisfied.

    These measurements were posted when this forum was changstar. It would appear that something happened during migration; most understandable given the tremendous amount of work involved by those tasked with the migration and keeping this site running. A mostly thankless and volunteer effort.

    Careful review of the data compared to Balanced Part A and B demonstrates that Single Ended Part A is a repeat of Single Ended Part B. Look at the graphs found at this location:
