DACs are a solved problem, all the manufacturer can do is chase zeros on the spec sheet [Benchmark], make the signal slightly worse [Schiit] or put it in an extremely ugly case [Chord, Cyrus]. The DAC in my receiver which does high res PCM, DSD, crossover, volume control and EQ costs two dollars from AKM. There's a running thread in the AVS 2 channel forum where a guy recorded a song through an $8 Apple USB C DAC, through a cheap cable that's too long then back through a cheap desktop interface and had a Foobar ABX test against the original file. Nobody has been able to tell the difference when testing but there's a whole lot of people who won't take the test and want to yell at him for hundreds of pages.

KozmoNaut posted:I would say "signal processing" rather than "production", really. 96kHz sample rate gives more than enough headroom to minimize artifacts from filters, similar to how 24 bit depth assures that you really don't have to worry about the noise floor creeping up into the audible range while messing with the signal, unless you really mess up bad. It's the "don't worry about it" setting. If you do signal processing at 44.1kHz and 16 bits, you have to know what you're doing to not mess it up. OH MY GOD loving FIIO. I bought a D03K to connect to my Samsung TV and apparently it just could not handle it. It does fine with 44.1kHz sources but does not handle 48 well at all.

Floyd Toole does argue for 20 bit playback. Technically, human hearing exceeds 16 bit resolution. In practice, outside of a purpose built, very quiet room and an exceptionally dynamic recording, no one would ever be able to make use of that increased dynamic range. That won’t stop people from trumpeting the superiority of 32 bit 384 kHz recordings, though. Is there even a DAC that can exceed an effective bit depth of 21 bits?

Yeah, it's a real mess and a drat shame, especially since it's specifically sold as a DAC for use with TVs that only have optical outputs available, and 48kHz is the de facto standard in the video world. At least on a PC you can force resampling to 44.1kHz and still use it.

I still swear on internal soundcards. For this mainboard having those stupid Nichicon gold caps, some shielding and PCB separation bullshit, and whatever the hell else, there's sure plenty of audible noise. And I'm not gonna put an ugly breakout box on my desk. Also, those Soundblaster drivers have yet to take my system down, and it runs 24/7.

I haven't had problems with onboard realteks in years. I get high-end motherboards so maybe it's different on inexpensive ones, but I thought that problem largely got solved a while ago except on bargain poo poo.

If you do want something external that doesn't take up table space and you have USB-C ports, get one of these: https://www.meizu.com/en/accessory/hifipro.html Or a Google Pixel USB-C headphone dongle. Probably the most discrete options out there. If I had USB-C ports in my PC and I wanted to replace my Topping D30 (and get rid of a mains power supply), I would just get one of those and keep my Atom headphone amp and be happy.

Probably not because there's not much room in them to begin with and adding more weight would make it much harder to balance. Also, that's silly. Just put it in the tonearm.

You wouldn't believe how brazen copper thieves can be. The cable manufacturing plant I work at, the copper drawing department borders at a steep incline, on top of which there's a fairly large meadow. They stored a bunch of barrels of drawn wire (1mm diameter) on the outside at the incline. Over a whole weekend, some thieves rolled up with a truck onto that meadow and spooled like six of these barrels empty over two days. Apparently some crappy motorized makeshift contraption to pull a couple of wires up the incline and spool them up in bunches. Which is interesting, considering on the other side of the meadow there's a row of houses and none of them seemed to either notice or were in any way suspicious. But guess at what moment the surveillance system was upgraded, tho.

I'm not having another weird dream I can't tell apart from reality, am I? Am I reading it right with the three cables in the $34k are for connecting a separate power supply via XLR to the DAC?

If you want to see a masterclass in misunderstanding digital audio in the most expensive and convoluted way possible I suggest this article. Basically dude gets a video doorbell and it makes audio streaming stutter on his wifi. The obvious solution would be to run ethernet for stuff you don't want dropoputs on. And he kind of does: quote:Below is a list of equipment for a basic setup: quote:Putting my scientist hat on, I went into full research mode and started reading everything I could find about digital streaming using copper Ethernent versus optical fiber. Here’s what I learned. quote:The purpose of using optical fiber and networking devices with better clocks and power supplies is to reduce sources of noise and improve timing of bitstreams. It was originally thought that digital sources and connections were impervious to the effect of noise on audio quality; after all, they’re just 1’s and 0’s, right? What can go wrong? Well, it turns out that bitstreams are not composed of 1’s and 0’s; that is only how the data comprising the music file is encoded. What is actually transmitted from server to DAC are analog square wave voltages. As result, it turns out that…everything matters.

All over the world people are reliably transporting multiple gigabits a second over copper just fine, but loving audio at 1.4MBbit, gently caress no, that requires a CERN level setup. Also, it still blows my mind every drat time that those idiots just can't grasp packet networks and that every device buffers packets before retransmission (being remodulated over a new circuit in case of switches and routers). Who the gently caress cares what's in between two peers, if the same bits arrive at the destination as they were at the source? Analog square wave voltages? Who the gently caress cares what the levels of the zero and one bits are, if all it does is trigger some hysteresis circuit?!
