    Thank god for that. Or, rather, thank Soltanzedeh for that!

    The wheels of medical science are wonderful, but they do sometimes grind exceeding slow. We can be thankful for the times when they get there while we are still here. Been there, with five years of don't know, until they eventually found something to remove (not even knowing what it was until they did) and surgery restored health.

    Apparently, a member of my mother's family was told that he had a few months to live. He may or may not have exclaimed Bullshit, but he did decide that he might as well sell up and go to USA to be a cowboy. He lived sixty years.

    This may be myth, but as another of her tribe was a ground-breaking anthropologist/explorer who found eventual retirement boring, so finished off his lifespan exploring Tierra del Fuego, it might not.

    You’re such a force of nature, Mike!
    I guess after tackling seemingly impossible math problems, cancer didn’t seem so hard to beat!
    Kudos to Dr Alphabet and your wife for figuring things out!

    My wife is an RN in neurology and says this is pretty new breakthrough stuff. She also says the medications they give to these CRMP epilepsy patients is really new and very expensive.

    Back to work, sorting out what the fuck to do first. One circuit block we really need is a Unison USB out – it would seem to be simple, right? Just turn around a Unison USB input. No such luck. It is an engineering nightmare in the same sense that it was on the Unison USB input. The chipmaker says the part will not work for audio over USB, either as an input or an output. Period. So why use the part at all?? It seems we made it work for the input. Besides, there are no other chips I know of that say they will. So to do our own USB audio I/O, we’re on our own. At the end of the development, we will have an edge, just like we do on the USB in. It is just that we really had to work for it, Dr. Ivana and all. Perhaps the real problem is that I just do not listen sometimes.

    We cobbled together one more new kinda DAC that seems to be interesting. Seems is the keyword, as the DAC got re-cobbled into a DAC evaluator circuit. It seems there are a few new DAC chips worth evaluating. If the chips survive the DAC evaluator, we put them in my own Yggdrasil just to try. We haven't found any “the king is dead – long live the king” DAC parts yet, but the trials must go on.

    That’s it for now. It is just I haven’t been back for that long. More will be revealed.

    @baldr Glad to see you back at work and can't wait to see what you'll release in the years to come. I imagine you saying "bullshit" to the chipmaker and get it to work for USB out.

    side note: glad UCLA Health was able to diagnose and treat your condition. They helped solve my own chronic skin condition that I suffered with for over twenty years. Several doctors and dermatologist couldn't figure out what I had until a UCLA doc gave a proper diagnosis. Turns out I suffered from Confluent and Reticulated Papillomatosis (CRP, and pronounced "crap") and haven't experienced an outbreak since treatment. I'm hoping all of the med students they brought into to see it first hand will prevent future misery for others.

    Mike,

    Great to have you talking about Circuits again instead of Medical issues!

    Cheers!

    We lost John Prine this week. The next day Ivana shows up and before the sun went down the Unison USB Out worked. Fuck-ton of bugs but good enough to compare to S/PDIF out. Damn - I then cued up JPs Tree of Forgiveness. What a loss, regardless of the sound good as it is. I'm listening to Bruised Orange right now as I write. You know, I have seen the Ring dozens of times, I have seen Earl Scruggs play Foggy Mountain Breakdown, and Janis sing Every Little Piece of my Heart. I've seen the David #1 but John Prine really works right now. The magnitude of the loss is now sinking in.

    Mike.... I once suffered what sounds like your symptoms. No doctor would have figured out. Even the doctor that caused it (oral surgeon) did not understand. Our brain runs on electrical current. If I have fillings in my teeth of differing alloys it forms into a mini battery via oral galvanism. Besides the high mercury content in the old fashioned metal filings, the metals themselves can play games with the electrical signals in the body.

    Well, I went to an oral surgeon who insisted that titanium implants are not really a problem after initially asking for the newer type, ceramic implant. He insisted it would be okay. About three days after the implant was in I began falling sideways when bending down to pick up something. Because I had other fillings in my mouth it was acting like a conductor for the galvanism one step closer to my brain. I begged the doctor to remove it. He insisted that it had to be something else and suggested some over the counter sinus medication.

    As time went on my legs became affected. They became heavy. It felt like I had weights on my ankles, and to walk just a block was a frightening experience. I found a blog online with others having experienced the same symptoms after receiving titanium implants.. I printed it out and showed to the oral surgeon who finally reluctantly removed the titanium implant. It took about two years for the feeling in my legs to return. I learned about an oil soluble form of thiamine (usually water soluble) that is used used by diabetics to help avoid nerve damage "Benfotiamine". It me got closer to full recovery.

    Long story short. I had to learn how metals in the mouth interacted to form oral galvanism which can effect our brain waves I probably would not be posting this today if I had not found out.

    Not sure what you got going wrong. But, thought I should say something just in case.

    Wishing you well, GeneZ

    How is your hair? Hairs are your aerials. They pick up signals from the cosmos and transmit them directly into the brain. This is the reason bald-headed men are uptight.

    Some people can pick up radio with their fillings. Wait... is this still a thing? And that weird feeling when biting on a piece of silver paper that got stuck to the chocolate is an electrical thing, right?

    So electricity and the mouth... not entirely complete-and-utter-nutter stuff.

    Granted, whilst strictly true, "Our brain runs on electrical current," tends not to precede a proper-scientific discourse. But I'd be interested in knowing if galvanic action between titanium and mercury is possible?

    ...Even though I am one of the many millions with both mercury and titanium in my mouth. My pair of implants has been there for sixteen years.

    Google suggests it might not be fiction. But then, I have no way of knowing what this amounts to in real life. It certainly hasn't been a problem in my real life.

    Hi Mike,
    I am so happy to hear that you are recovering and back at work breaking the rules! I have enjoyed listening to your design magic for over 25 years.
    Stay well!

    Probably best to avoid this subject in a forum as sophisticated as this but fuck it, it is meant partially in jest anyway. (With apologies to Fred Reed). So here we go: What is the point of measurements? Who decides(ed) which ones are significant? AES? Julian Hirsh? I always tended to do them on prototypes without considering WTF I was doing and why. Granted,if the prototype is really fucked up, the measurements will tell. But really, who cares if the S/N is -120 or -130db. Bragging rights? Self hand job? What are we doing with our measurements that indicates we really know what we do? Are there better tests? Faster ones? I have never read a paper on the methodology on the need for, suitability, and development of such tests. Bam, the key word is methodology. There is so much audio thinking that resembles an amoeba globbing around, slowly and randomly. No methodology. In fact, my bragging right is methodology. You can’t build Schiit that lacks prior art without it. Come to think of it, art is an interesting word in this context. Subject for another missive.

    Take that to the sound science guys. Sometimes it seems the only certain knowledge over there is that they haven’t any. Nothing that make me sport audio wood. Kinda like trying to read Bertrand Russell. High IQ but talks/writes way too much; insufferable. Another reason that measurements are suspect is they are defined in a plane. Ninth or tenth grade Geometry. The whole of Geometry is points, lines, angles and planes. Suitable for defining an audio measurement but useless for a taco, a cheeseburger, or the feminine mind. Hmpf.

    Measurements provide static evaluation of a component's ability to reproduce accurately some input signal. Problem is that most measurements are simple sines and don't adequately convey meaningful information on dynamic behavior. Further, the simpleton's approach of lower distortion measurements must be better completely ignores the case where certain specific distortions are actually enjoyable, even preferable. Currently the only method for evaluating dynamic performance involves actually listening with ears, not eyes. The site to which you refer is absent the ability to achieve higher level cognitive function in understanding more complex concepts such as these.

    Well the science guys bitch and moan about thd but ignore imd. They would throw a fit about Lavry and SPL stuff like they did Schiit if they could afford them but they can’t. They don’t like paying 5000 bucks for a metal box even if it’s gold plated. they totally handwave IMD and rising distortion in treble. The French dudes who measure stuff always listen and measure for shitty digititus treble as the first measurement but aren’t “scientific” like the dudes building shitty dsp speakers.

    If those fools found out 90% of popular music has been through a Pultech or SSL bus compressor, not even considering API and Neve pres, they would kill themselves.

    With the risk that I am stretching to things on the audio engineering domain on which I have no theoretical or practical credentials, a philosophy of science point of view:

    From science perspective, all the scientific methods like applying mathematics to build theoretical models, or statistical analyses of any data sets of real-word phenomena, surveys via questionnaires, or controlled measurements are meant to find the truth about the world. The more independent the results of the the methods are of the confounding variables like the researcher, the particular data set, the equipment used, the context, etc. the better.

    From engineering science perspective, the above applies, but the model and methods must in addition be useful in designing solutions to practically relevant problems. Otherwise, they obviously are not worth doing (for engineers).

    The latter point brings in things like how do the measurements correlate to perceived high quality (however defined) recording and re-production of audio (which is the fundamental problem being solved), what measurements are effectively measuring this, and how the measurements should be done in a cost-effective manner. Codifying this typically leads to engineering methodology and building tools supporting that methodology. The measurement-outcome dependency and effectivity of the methdology can be studied in controlled test setups with small focus groups (like Toole), and ultimately the test is the market: which solutions and the methodologies are adopted into use.

    Maybe the above is self-evident.

    The reason I wrote this is that as a layman it seems to me that the biggest gaps are in the topis of the last section above. Having some experience in another engineering science domain, it has been nagging at me that there is some anecdotal evidence that the standard measurements do not seem to capture what we hear (e.g Purr1n's blind listening of perfectly measuring devices and being able to differentiate them and similar things from Innerfidelity's blind listening of top-of-the line amps). And a lot of claims that people do hear differences.

    If I were an audio science researcher I would be curious to do research in this area to find out what the hell is happening here. I would hesitate to say that there is nothing to be found and current theory and measurements tells enough of the truth that no further research is warranted. (Nothing in science is the full truth. All theories are approximations.)

    Jesus, Ivana gave me a new Unison USB out set of software. Holeee fuck!

    Now I must fess up to being a bit of an audio curmudgeon. But I am also an incurable music romantic, with varied pleasures. I get chills and moist eyes when I hear an appropriate bit of music or musician. I admit it, my favorite soprano of all time is Elisabeth Schwartzkopf. Granted, she was a member of the party albeit apolitical. I read an English bio which insists she joined the party only to be cast in the preferred roles at the Berlin opera. I originally became a fan of hers in the 1960's and had no idea about the political stuff until I read the bio a year or so ago.

    Von Karajan, on the other hand was an enthusiastic party member who was exiled to Paris. Furtwangler, not a National Socialist at all, remained in Berlin as the senior musician in the Reich. Musical giant that he was, he defended and kept all of his Jewish musicians and made sure they were properly treated. Ever the asshole, Von Karajan made sure he opened every Parisian concert with the Horst Wessel Lied in order to taunt his French audience.

    Really ironic that the Nazi fanatic Von Karajan ended up with Cat Bird Seat recording contracts for the rest of his life with EMI and Duetsche Grammophon. Excessive for an insipid conductor in the context of Furtwangler, who, on the other hand was singled out as the musical Nazi primarily by occupying Americans. He recorded little after the war, until his death in 1954.

    Hans Knappertsbusch, an amazing conductor in his own right, noted an experience when his assistant conductor was rehearsing the orchestra. Furtwangler walked in the rehearsal hall and stood in the back of the hall. Knappertsbusch reported that as the orchestra (The Berlin Phil) noticed Furtwangler’s presence, the quality of their playing significantly improved.

    Apologies for the digression. I hope I am not just writing to myself. Where I was headed was that I absolutely loathe Baroque and JS Bach in particular, although I acknowledge the musical ability. To me, baroque sounds like bad bluegrass with warbling vocals. As I write I listen to Bach’s B Minor Mass, (yecch!), conducted by Herb Von K (double yech!!) but with Dame Swartzkopf providing the requisite chills.

    Another 40 minutes and I will play “Bags and Trane” and then probably some Little Feat. There must be something to a rocker who died of obesity rather than drugs. At least no fuckin’ Nazi controversy.
