Re: BWGK on Vinyl
There's always a point of no return though.
DSD is 1-bit samples at 2,822,400 samples per second.
If anyone thinks they can tell the difference between SACD and a perfectly clean vinyl, they're kidding themselves. However given that it's impossible to play a vinyl and SACD on the same player, it's impossible to ascertain what differences would be from. For example, using a pair of Martin Logan Summit speakers - a $5,000 Rega P5 with a good phono pre-amp and Roxsan amp will sound much better than a Sony entry-level SACD player hooked up to a $500 home theater receiver. Much in the same way as the $7,000 Marantz Reference SACD player hooked up to the $14,000 Marantz reference pre/pro set-up will sound far superior to a $150 Denon turntable hooked up to an entry-level home theater receiver. You choose where to go.
That's why DSD is preferrable to most discerning listeners over DVD-A, because DVD-A, while 24-bit, only uses 96,000 samples per second (192,000 for stereo).
DSD much more closely resembles an analog waveform and can actually be more accurate for frequencies outside human hearing as it has frequency response of 5Hz to 100kHz. Where digital suffers from jitter, analog suffers from resonance.
As for vinyl, if you're not using a very good diamond stylus properly aligned and tracked, your record IS a lossy medium because you're eroding it every time you play it.
Properly set-up a good stylus will actually polish the records grooves and sound better with time.
It is easier to get good sound from digital, but if you're willing to spend some money and have patience to get good pieces of equipment then vinyl is the easy choice. Not only when done right with good stampers is it a wonderful aural experience, but there are 60 years of recordings available to choose from through sites like Discogs, etc., and you'd be amazed how many unplayed recordings there are out there. With SACD, there are 5,000 recordings, mostly classical and jazz.
It's a shame they fucked it up (Sony, Warner, EMI, Universal) because SACD would have been the ultimate future for music - ease of set-up, storage, fidelity, multi-channel, hybrid CD's for other players, etc.
Hopefully they get it right with Blu-ray. But for the next few years vinyl is the only choice for those who want to hear the music at its best.
In addition the source has to be analog for vinyl to be 100% authentic to the source. If it's DXD or any digital format, then both the digital and vinyl will be the same providing the digital medium is capable of the same resolution as the source.
DXD = 32/384, no medium out there for this. Not anyone in rock using this afaik though. Most places should have both an analog and digital master, then you have to ask if the mixing was done on both analog and digital.
There's no straightforward answer.
