…I have three DACs connected to my Roon PC. Two are wireless over raspberry Pi’s and one wired with a USB. All three perform equally great!
It reads more like a stream of consciousness altered by a psychedelic drug than anything actually useful.
It's probably the amphetamines and quaaludes kicking in at the same time.There is no end to this perceptual drivel:
"That record through this system [a list of components], with this xxx amplification, produced the most realistic piano sound I've ever heard in my room, in every known sound-reproduction parameter and probably a few that are not yet known. [...]
The xxx amp, alone and combined with the yyy preamp, seems to up the pace of everything, as if your turntable is running fast, while simultaneously digging further down into each musical instant, making each gesture live longer, with precise attack, generous sustain, and long decay. The amp simultaneously speeds things up and slows things down."

Musicians call that rubato, used to artistic effect. I am not sure it's something amps do, nor would I want them to even if they could. But I suppose analog tape can do it, shrinking & stretching....... The amp simultaneously speeds things up and slows things down."

Darko's argument are quite feeble to put it mildly. First, digital does not exist and in fact it is a fabrication, that we humans have devised to literally "integralize" sound. To go to the ridiculous, but feasible, I could have a speaker that emits a bark for 1 and to take into account jitter, the absence of a bark means 0 and you introduce a period of .5 sec, so that in case you take a bit longer: Oooh, there's jitter. On the other side a microphone connected to some mechanism notes bark -> 1, no bark -> 0. Hooray, we're in the digital domain with 1, 0s and jitter cause wind you know.A new argument has developed that transmission of digital audio is really analog. And for this reason, everything digital can be subject to audible difference from digital audio cables to digital output of streamers.
I just saw Amir´s comment about Darko declining to let him talk on his channel. I don´t know about the veils, but the smell of piss on the legs reaches the Mediterranean.
Bingo. It's good that more people understand this stuff, but he has his own agenda.Is it me or all Darko's argument is just pure justification for overpriced fancy streamers?
Because if digital is not digital really, it is subject to all the Anunnaki Technomagic that reviewers love to verse around analogue...
Which one can only assume is the enrichment through either ad revenues and/ or discounted equipment of one John Darko esq.Bingo. It's good that more people understand this stuff, but he has his own agenda.
I doubt it's an altruistic urge to teach.Which one can only assume is the enrichment through either ad revenues and/ or discounted equipment of one John Darko esq.

Does a digital signal have both negative and positive content? Always thought it was zero or one which is always shown as being positive above zero.Darko is a smart guy. He is just doing the talk to keep people showing up at his YT channel. If a signal is AC which a digital signal is, Its an analog wave. Look up square wave. Point is the one´s and zero´s is extracted from this, ideally at 100%. The digtal signal needs to be of such quality that the converter kan lock in time and phase. This is not a problem to achieve with modern equipment.
Depends on the format, and how strict your definition of "binary" as a digital number. One or two's complement encoding has positive and negative numbers. Many of the converters I designed used straight binary (0 to 2^n - 1) or some other type of encoding (e.g. Gray) to save power (conversion was done elsewhere in the processing chain, at lower speed). I remember decades ago a couple of professors debating if two's-complement was truly "binary" or a different number format (semantics). Me, I just did what they told me...Does a digital signal have both negative and positive content? Always thought it was zero or one which is always shown as being positive above zero.

Most digital number representations in general use, or at least as I use them, have the means to represent negative numbers in fixed- or floating-point schemes.
Some digital filter and modulation problems are easier to analyze using -1 and +1 instead of 0 and 1. Still binary, only two levels, but the math works out better since you can produce "0". Heck, what is life (or math) without zeros?
