Schiit Happened: The Story of the World's Most Improbable Start-Up

    There might be a few 'technical issues' but they are usually overcome with $$$$$.
    Like the 8KV plate voltage, the 100amp at 7.5V filament voltage needs, but the power of 47.7KW power output MOAR than makes up for such piddling concerns.

    MOAR POWER is ALWAYS better!
    It's the uhmerikan Way.

    LOL! Definitely a manly-man's tube with 8000 volts on the plates, 100 amps on the heater, and 100x the amplification factor of a 6080. Should be enough to drive low impedance 'phones to moderately loud volumes. :sweat_smile:

    Thank you for the explanation, it indeed seem to corroborate very well with what I am observing:

    With gaming optical mouse:
    USB, 32/192: At least 4 episodes of jittery mouse movements per 24 hours
    Optical (direct), 24/192: 1 episode of jittery mouse movement within this 24 hours, some pops before playing certain non-24/192 files (most probably due to upsampling?)
    Optical (converter), 24/96: 1 episode of jittery mouse movement within this 24 hours, more pops before playing certain non-24/192 files (most probably due to upsampling? Even 24/96 files are affected though)
    USB, 16/48: Testing right now, no issues so far

    With generic optical mouse:
    USB, 32/192: No episodes of jittery mouse movements per 24 hours

    Given that this jittery issue happened even before I upgraded to this brand new computer and changed into this new powered USB hub, I think the problem lies more with this particular gaming mouse. I suspect its age may be relevant, it was a 6 year old model which means it may not have sufficient USB shielding to keep up with current data rates and also its optical sensor may be on its way out. Will take a look at the 12.12 sales we have over here to see if I can get a new one for a good price.

    This issue also means I may need to look into using a PCIe solution instead of USB or onboard audio for my audio needs (digital audio out and line-in recording) but I think I'll deal with the mouse thing first

    Of course you realize the size this amp would occupy right? (It would be about as big as a step van.)
    And of course the 47.7Kw would require the electrical service capacity of a regular small house, all by itself.

    But heh the quest for a shake the house down around our ears amp, not to mention the speakers to be able to handle this (they'd be about the size of a castle) is eminently doable.

    So spare no expense, and lets not hear anymore 'quitter talk', so we can get a move on! :beerchug:

    Times a waste'n, were burn'n daylight, are we done yet? :ksc75smile:

    hahahahahahahahahaahahahahaa :ksc75smile:

    (...after a week of listening...) I'm really enjoying my combination Bifrost Multibit 1.x and Asgard 2 classic stack. I was concerned the Asgard would be anemic when compared to my Magni3. And I fretted that the Bifrost would be ho-hum when compared to my EITR-ModiMB. Hell, I even was concerned that my HD6xx headphones would sound 'meh' on my Asgard 2. I. Was. Wrong. Did I want to get all butch and buy a Gungnir MB and a macho-man Mjolnir? Of course. I just couldn't justify the the balanced XLR outputs/inputs. It was unnecessary circuitry for my needs.
    I like being wrong sometimes. :ksc75smile:
  7. bcowen
    Yeah. And?


    Restraint and practicality are two words that are noticeably absent from my personal audio textbook, but I set a limit on 24 output tubes after some amps I had in the past. Fortunately they were monoblocks so only a dozen matched tubes were required for each. :grin: Guessing you'd probably need to start with around 500 tubes to end up with 160 that matched up closely....

    I was planning on building something very minimalistic for Mr. Cowen, two tubes, a headphone jack, a volume pot and associated circuitry. Even GE tubes might cost too much for what I have in mind for him.

    Here is a visual aid.... think something like this:

    upload_2019-12-14_9-16-20.jpeg practically the same thing, only different. :smile_phones:

    Since I'm used I'm used to the Lyr 3 with one tube, two tubes will double the complexity. Just sayin'. :grin:

    Fine. But mine will get better tube mileage.

    Very true, now as far as appearance, I plan on sparing no expense. I am searching for just the right materials for the top plate.


    And the, um, wooden base...

    [​IMG]I may not use point to point wiring since that involves solder and soldering but i will figure out some method. Wire wrap, clothes pins, paper clips, I have all kinds of possible options. My budget for this project is $19.95, about the price of a Popeil Pocket Fisherman.

    Functionally equivalent.

    Schiit, I found the four tubes of the Valhalla 2 uncomfortably hot for South Florida. I guess you blast your AC or like feeling like you're in a sauna?

    Top plate needs more patina (aka Rust). :wink:

    Physical comfort is irrelevant in the quest for audio nirvana. Come on Rick. You obviously haven't had your coffee yet. :smile:

    With rust a can might become an objet d'art and gain value. I figured I could just have someone follow Bill around and wait for him to open his car door and collect whatever falls out. I figure with recycling prices, I could easily break even on this project or come out ahead.
