DSD, to support or not - Page 8

post #106 of 110

Yeah that makes no sense considering RR does excellent 24/176.4 recordings...

 

The other factor is that now me and my friends are having terrible luck with "remasters". Probably about the last 10 out of 10 hires downloads we've bought have been worse than out previous CD or DVD-A (24/96) rips. Now the always seem to be compressing the dynamic range and push the treble (I guess to prove there is more detail there)... Either they are just using a single remastering for streaming, radio, and headphones, or they just don't get it... Grr...

I'm sure someone has said already, but the company Ifi claim they did extensive research into which chip is the best for DSD and chose the Burr Brown 1793 (prior to TI's acquisition of the company and the PCM1793). They say it seems to be the only chip designed to do both DSD and PCM equally well, or words to that effect.

I do think there is a future for DSD, but not in the traditional separate DAC/Amp sections that we use today. DSD is a pulse density modulated(PDM) signal that is extremely similar to the pulse width modulation(PWM) that class D amplifiers use. This means you could maintain the purity of the signal by discarding the DAC and feeding it straight to the Class D processor with some minor conversion of the signal but nothing like the D/A conversion required for a typical setup.

 

There are very few truly digital amp, like the NAD M2 amp, but I am sure they tend to take PCM and use some sort of signal processing to make it compatible for the class D stage. Starting with a DSD signal seems to reduce the potential for signal modification in this setup and would reduce some of the hardware requirements that go with it.

 

While this probably won't happen exactly as I described, I do think it is inevitable that we'll have systems that maintain a digital signal until the headphone outputs. For speakers I think it will go even further with an amp at each driver that are fed signals from a DSP instead of using passive crossovers, thereby maintaining a digital signal all the way to the speaker drivers themselves.

Here's my two cents. I think DSD material sounds good, but the format itself doesn't matter as long as the recording and mastering (if any) are all done in DSD.

The big flame war is on the playback format itself and I don't think the playback format itself manifests any benefits. What I HAVE found is that native DSD material often sounds better to me exactly because working with DSD is so limited. With native DSD recordings, you get a very raw, unedited kind of sound and I really like that. The producer has to place much more effort into getting the DSD recording just right because he/she knows that you can't really "patch things up" in a DAW like you can with multi-bit Delta-Sigma or PCM recordings.

As for support in a DAC, I think having the ability to playback these recordings is nice. The vast majority of material is PCM on the other hand and very few people actually have native DSD files if they even have DSD material. DSD to PCM, edited, mixed, and mastered in PCM, and converted back to DSD absolutely destroys the the sound quality in my opinion because you've manipulated the audio in a DAW just like any other PCM track out there, and the added effects and stuff change how the track ultimately sounds, which you can't really do in a pure DSD track. That would be like making a binaural recording and completely negating the benefits of the binaural effects by adding-in a whole bunch of other non-binaural stuff to a track; what was the point of even having the binaural recording in the first place if you're just going to "patch it up" with other sounds?
