When is digital going to get the soul of music?

Learsfool - could you clarify how do you know that digital processing cuts frequencies around 20kHz? I run test frequencies at different levels from standard CD and 20kHz is present at about 0dB (in relation to 1kHz level).

Albertporter - you are probably right - I would pay more than $30 if for many recordings but not for some of the popular music - classical and jazz hits last longer. It takes marketing campain and often break-even prices to establish and popularize standard. Do you remember Iomega computer Zip drives? It never became standard because Iomega didn't want to lower media price and sued everybody who made compatible media.

Would recent digital masters in DSD improve SACD? (pretty much the same format). I remember Stereophile's very positive reviews of SACD.

I don't remember claimed equivalent of 2.8MHz bitstream but I thing it was something around 20bit/90kHz (with quantization noise pushed outside of audible range). Wouldn't CODE with 24bit/96kHz be better? Most of people have DVD players and my Benchmark accepts 24bit/192kHz.

Kijanki, as you no doubt are aware, every digital processer is totally different, so it is impossible to generalize about all of the different designs. I see, re-reading my post, that that was not worded very well, and was too broad a generalization. Many designers do in fact cut off many of these supposedly inaudible frequencies, however, considering them extraneous. And even in the very best products, the processing itself has unintended effects that they have yet to figure out. Many believe that it is not ultimately possible to take sound, turn it into ones and zeros, change it back again, and have it come out the same. Without turning this into a very boring technical discussion, two common examples are harmonic overtones being removed, and the disappearance of the sense of the surrounding air. Digital processing, again very generally speaking, tends to take away, or at any rate cloud the differences between the timbres of individual instruments (especially acoustic instruments), and also tends to blur the soundstage, making it harder to determine exactly where the instruments are located in the original space. This accounts for why many people find digital sound sterile or fake. The very best digital is getting better at presenting a three-dimensional space, but it is incredibly difficult for digital to do this, and they are still working on it. Analog does all of these things with ease. And I am a little surprised no one has mentioned the jitter factor, which is a huge degradation in sound quality, and which even the very best products you mentioned with 24 bit/96kHz sampling have failed to eliminate entirely. I think I've said enough on the subject, I hope that was more clear.

An absolutely excellent post Learsfool.

I was not aware that digital had these inherent flaws. I always thought that given sufficient sampling rate, it would eventually sound like analog.

I have quite a few LP's pressed from digital masters and some of them do very well, sounding as much like analog masters as not.

I'm saying this, assuming Alison Krauss, "live" (2002) and Radiohead, "Kid A" would be samples of digital masters. I cannot imagine either would be analog considering when they were recorded.

I have some recordings, ECM in particular that sound digital, even though they are LP's. The one's that come to mind are older stuff from the 1980's.

This is why I made the claim that a great digital master converted to analog at the studio and pressed as an LP can be wonderful.

Learsfool - everything depends on the quality of processing. It does not remove high or any other frequencies (it can be easily proved) but suffers on details of conversion. It might be, I hope, one day possible, to get perfect quality of digital master at home. It is getting better and better. Jitter you mentioned is just noise in time domain and now is effectively removed in some DACs. There is also another type of jitter - one in A/D processing and that one cannot be removed. A lot of older recording were transfered to digital media for storage with poor A/D clock and jitter stays forever unless analog recording still exists somewhere.

I probably don't have as good ears as yours because top quality gear and great SACD recording would make me very happy. One compromise I agree on is practicality of digital media while the other is my limited budget. I don't want to invest now a lot of money in analog - it's just to late for me and my priorities are quite different now than 20 years ago. I have long way to go in audio from where I am now and when I get "there" technology will improve greatly, I'm sure.
