| what is the purpose of the analog part in the DAC Yes all DAC chips output analog signals but they're often not in the right format for sending to a preamp. For example many DAC chips output current rather than voltage so require an I/V (current-to-voltage) stage. Many DAC chips output balanced s... | |
| Do we really need anything greater than 24/96? Opinions? Here’s another thing to consider. Upsampling is guesswork. Upsampling generates data that can only be a guess as to what happened between samples. Nope, newly generated data is fully constrained by the input samples. Assuming no violation of Ny... | |
| Chord mscaler - what’s so good about more taps? What are taps and why do I want em? Taps are the number of samples stored which the filter calculation is performed on. Performing a filter on a longer sequence of samples allows a sharper cutoff and/or better stop-band rejection. | |
| Basic technical question about digital source signals Not really, it presumes that subsequent filters (mechanical limits in your speakers and your ear, which respond per F=MA; inherent limits in subsequent components) achieve he filtering. There will be no aliasing after the DAC. Yes, there could... | |
| Basic technical question about digital source signals Not broken, a design decision to go NOS without a filter. Its broken in the sense that such a design decision breaks the theory of digital audio. Just as a design decision not to band-limit the input breaks the theory. | |
| Oppo 105 with DIY LPM is a giant killer (no dac needed) Or to put it another way, the "glare," probably produced by jitter, is taken care of in some good measure by the better clock in the DAC. In this case the glare is caused not by jitter but by common-mode ultrasonic noise from the Oppo's intern... | |
| Looking for a vinylesk sounding DAC Fake -- Lack of a reconstruction filter in a typical NOS DAC allows high frequencies (aliased images of the original signal from the stair step) to pass which when they hit things like tube amps and speakers with high distortion, they generate f... | |
| Looking for a vinylesk sounding DAC The fake air of a NOS DAC running at CD sampling rates Curious - what makes it 'fake' ? | |
| R2R Ladder DACs or All in One Streamer Solutions ...he’s still going and using I think an R2R d/a conversion still, the one AMR also uses in their DP-777 dac the TDA1305 which was originally made by Philips for Discman use!!!! Looks as though you've confused UDA1305 with TDA1305. The former is ... | |
| R2R Ladder DACs or All in One Streamer Solutions By using the comment "cheap no name Chinese DAC" you are showing yourself to be the real racist False - rather racism is shown by projecting it onto others in the absence of evidence. Which @georgehifi did do in this case so my conclusion is th... | |
| R2R Ladder DACs or All in One Streamer Solutions Get off your racist pulpit sunshine, of course the Chinese are extremely capable, just like anyone, just look at a few these days Holo Denafrips, etc etc T'aint racist to critique Taobao DAC offerings - I've bought plenty and implementations in... | |
| R2R Ladder DACs or All in One Streamer Solutions ...I point out that it was not too long ago that DACs based on the 1541 were not considered good, but suddenly they are again. Have you noticed that implementations of the 1541 have changed in the intervening time? My first CD player used LM8... | |
| R2R Ladder DACs or All in One Streamer Solutions They DACs they enabled sounded bad 30 years ago. Do you have examples to share where the bad sound was the fault of the DAC chip? | |
| Toslink I can't think of a mechanism for a volume change with optical cable change, no. Doesn't mean its totally impossible though. | |
| R2R Ladder DACs or All in One Streamer Solutions How did a DAC that was way behind the times 30 years ago (TDA1541) magically become good? I’m no believer in ’magic’ but seems to me that times changed in the direction of better numbers (THD, SNR) and not in the direction of better sound. So ’be... |
