  1. Well, two years later, I'm thinking about finally finishing up a Mini Dynalo build. Last time I was working on it, I stuffed the boards but failed to solder the on-board regulators (even though I used a stencil with solder paste, I still suck at such fine hot air work). I picked up the AMB sigma78 and sigma79s, and noticed they mismatch the U5 and U7 areas on the PCB. U5 and U7 have holes for 5 pins, but the regulators have 3. It looks from photos others have posted that the outside pins are ignored. What's up with the extra holes on the board?
  2. You need to look at the software you use (DJing sounds like you need some pro audio support) and make sure it works natively on Apple’s new CPUs, or at least through Rosetta2 binary translation. If it is not supported for any reason, buy a MBP now while you can still get one with an Intel CPU. If you’re good with Apple Silicon, then definitely hold off on buying a MBP. If rumors are to be believed, a refresh will come soon (this fall, so within a few months) and will bring a new form factor. Supposedly, it’ll get rid of the idiotic Touch Bar on the keyboards, bring back MagSafe power connectors, and bring back extra ports. As far as typing comfort goes, just buy a nice external keyboard. I rather like Keychron keyboards, for example. Battery life and power management sucks compared to Apple external keyboards, but the typing feel is massively better.
  3. Doing anything else with digital media is nervosa. Streamers? Roon? Pi2AES? FFS.
  4. Wait! Does this mean Audeze finally managed to make a headphone that doesn't make violins sound like violas?! @Beefy: Re: “electrostats seem to have stood completely still, while planars and dynamics have come forward in leaps and bounds” — my observations from attending numerous (large) meets for several years before covid have been that no TOTL planar or dynamic beats my SR-007 (v2.5 I guess?) and Carbon combo. Not the Utopia, not the LCD-4, not the piece of shit Abyss, nothing Hifiman (haven't heard their $6k thing though), not the Meze Empyrean (though that thing is pure catnip for bassheads). They're nice, sure, and most have the advantage of not needing much of a specialized amp. But they're not nicer than the current-production 007 or the 1993 SR-Omega (which I don't have, alas, but have had the fortune to try once). This opinion is unpopular on other forums. 🤷🏻‍♂️ Maybe this means there's a (local?) maximum in headphone quality, and various manufacturers are slowly reaching it. @spritzer: What amps do you think the measurements are coming from?
  5. @ShortBtwnHdset: Don't let Pars scare you away. No build guides doesn't mean you won't get answers. The Dynalo is easy. That kit you bought looks pretty good, assuming the MPSW parts really are genuine and matched as advertised. Look at BOMs, but above all follow the silkscreen on the boards. Stuff the boards. Check the GRLV board you have for the type of transformer secondary windings you'll need, whether center-tapped or not (there are a couple of different GRLV versions floating around). I used an Antek 50VA 22V for a Dynalo, it worked great, but might not be right for your GRLV board. This thread will have more info. Do you know how to safely wire up mains? That'll be the next challenge. It's also not difficult, but needs to be done carefully and correctly. While the wiring is pretty self-explanatory, you'll also need to ground the amp correctly to avoid noise. Again, there's info in various threads (including the KGSSHV thread), and feel free to ask when you get that far.
  6. I love the Zenph version of Gould's older Goldberg Variations recording. As far as I can tell, the same amazing playing but much better recording quality. I'm ambivalent on the binaural versions compared to vanilla stereo.
  7. The other bad thing about Focals (which I brought up years ago on this thread, but worth repeating for anyone considering it): the headband creates a hotspot. It's not flat along the skull line (unlike, say, the HD800 headband, or Stax-style suspension straps), but kind of cylindrical. For me at, least, the discomfort is immediate. One brand that I haven't seen discussed much here on HC is ZMF. Due to circumstances over the years, it's one of the few high-end headphone lines I have never had the opportunity to try out. If anyone has, opinions? (I already know if my 007 dies, I'll repair it or just get another one, but if my Audio Zenith PMx2 dies, there's no way to replace it with Oppo out of the business. So it'd be good to know what can live up to it. Focal is absolutely not a contender for me.)
  8. Where are you moving the data from the old media?
  9. In my understanding, setting a higher sample rate will cause the OS to digitally upsample or downsample the source material to match. I don’t know if it’s audible from an ABX test perspective, but it mucks with the signal. I suspect it doesn’t matter for upsamples of multiples of the original (like 44kHz to 88kHz or 48 to 96), but interpolation (44 to 96) might introduce artifacts. (I might be wrong about this.) A higher output bit depth than the source material should be fine: the extra bits will be set to 0, and that’s that. No information added, removed, or changed.
  10. Audirvana switches bit rate without necessarily taking exclusive control of a DAC. Is there any advantage to exclusive control? I find it annoying — you can’t just pause music playback to l, e.g. watch a video in-browser, you have to fully stop and lose your place in a track or playlist. Oh, and Apple’s jukebox software still not switching rates automatically is just silly. C’mon.
  11. I’m on the Qobuz trial, too. Playing through Audirvana, which gives 90 days. Enjoying the curated content, and it actually sounds better than Tidal to me. Too bad there’s no easy way to ABX, or I’d give it a shot.
  12. There’s now a part 2, if you feel like spending some more time: There’s pure insanity going on surrounding this on various forums. The pro-MQA crowd is now engaged in trench-warfare trying to discredit the guy who posted these videos. Changed its tune to “well we never said it was lossless — it’s lossy but BETTER than lame old lossless!”. There’s an edit war going on in the Wikipedia MQA article.
  13. @TMoney: Your battlestation photo is disturbingly lacking in headphones and a slick amplifier 😁 But I’m with you on this. I’ve been low-key trying to replace my Mac laptop with my iPad (and I don’t have one of the new ones, just an OG Pro from 2015) and an external keyboard. It’s close. I personally could probably jump ship if an upcoming version of iPadOS has (1) a Unix shell and (2) background processes. It seems like something Apple could bless us with. I’d also love external storage slots, but they’re not strictly necessary.
  14. The recent outcry over the MQA scam, and Tidal’s complicity in it, probably should be mentioned on this thread. This video started it a couple of weeks ago.
  15. Does anyone have 4CP-601 pots in 10k audio taper that you’d be willing to part with? I have now run out of my supply from this GB (my goodness, so long ago) and want to buy a couple more.
