    Yeah, I saw. I was hoping to buy the gumby with Analog2 if/when it comes out.

    Here's a pic BTW :)

    For what it's worth I find Mimby to be very excellent with SEX 3.0 and my cans, and yet Gumby with that combo is even more excellent. Both of them I consider pretty sweet devices, particularly the latter which originally opened my eyes (ears) to the multibit sound. Many thanks to the kind local enthusiast who loaned me his personal unit!

    Eventually I bought the Modi MB - but given enough time I went and got myself a Gumby of my own. I am very pleased with the result, it is a solid upgrade. Mimby does amazingly well for it's price, but it sounds somewhat lesser in comparison to it's big brother. The manner in which Gungnir Multibit readily serves up low-level detail and microdynamics on a smooth, and spacious stage is just addicting as hell.

    I was in a hurry and didn't create the mousepad cutouts necessary to avoid blocking ventilation holes on the dac1421. Result after brief photo session was black rubber marks on the dac1421 top surface. Took awhile to clean off. Custom cut mouse pad separators now created.

    They are 5.5 cm in diameter. Need to leave a minimum of 0.5 cm between them. It might be too close for your wonderful sounding Liquid Glass.

    Those Psvane 6SN7-SE tubes aren't going to fit. Not enough space behind and to the sides for them to fit. Negative clearance. Unless I find some 6 cm high tube socket risers...

    I have been thinking about trying the Psvane CV181 tubes.

    Sorry @Cspirou , I somehow missed this. Yes, there will be measurements sometime. Not sure they will happen before my multi-week break.

    No prob Bob. I just like knowing what's in the measurement queue no matter where it's prioritized.

    atomicbob's nuclear schiit

    Listening to this system for several weeks. Was demonstrated at the Seattle Summer Can Meet.
    Important to note Modi MB is v2 firmware in this system.

    01 Eitr - mc-3+ LiveClock + FS725 - Modi MB v2 - Lyr3 6SN7SE - HD800J - small.jpg

    Hardware block diagram:

    IVS setup for this system:

    Digital flutter management (jitter):

    Digital wow management (wander):

    Expanded y-axis view of LiveClock with - without - with Rubidium reference disciplining:
    06 20180801-1400 5384A Mutec MC-3+ frequency drift zoom.png
    All that can be measured during FS725 disciplining of LiveClock (before and after) is HP 5384 LSB toggle. Middle section is LiveClock running on internal clock alone. Not too shabby but not as good as with FS725 engaged. HP5384 frequency counter time reference was obtained from a Jackson Labs Fury GPSDO with Allan Deviation an order of magnitude more precise than the Rubidium time reference.

    This fellow is doing something similar in the world of karts - a visual analogy.

    For those with a burning desire to know system BOM:
    08 20180812 Headphone System List Eitr MC-3+ LiveClock FS725 Modi MB v2 Lyr3 HD800 Jmod - IVS.png

    The proof is in the listening. I've been very pleased with the results of this system's synergy.

    Before anyone contemplates replicating this system, I can justify the FS-725 Rubidium time reference for lab frequency counters, Antelope LiveClock provides house clock to project studio as needed, and the MC-3+ was already in lab inventory.

    Consider the Eitr, Modi MB v2 firmware, Lyr3 + PS Vane 6SN7-UK, HD800 modded to suit personal preferences and my IVS will deliver a high percentage of this system's performance.

    Those short term vs long term comparisons of the signal stability are most intriguing.
    It makes me wonder what identifiable acoustic aspects result from those series of tweaks.

    And the Fury reference master clock is intriguing to contemplate as well.

    Thanks for that in depth look see. :)

    I have been more and more pleased with the combination of Gumby (recent purchase, with Gen5), SEX 2.1 that I built, and stock HD650. I no longer feel the need to tweak or change my headphone setup. Most recently my son kicked me off the listening chair:

    The little dongule is a voltage divider I built since the SEX is too powerful.
