RE: How Come No PCM to DSD Stand Alone CD Players Yet?

Hi,

Any CD-Player with a Delta Sigma DAC (read AKM, Cirrus Logic, NPC, some Philips Chipsets, many Sony Chipsets and others) since the late 1980's to today converts PCM to DSD, most often to DSD128 for more recent Delta Sigma DAC Chipsets, some even do DSD256.

More advanced DAC's (e.g. latest Burr Brown & ESS) use multibit delta-sigma hybrids (with differing implementations) which provide a further advance over single speed DSD.

Now the precise modulators and filters used will differ between different chipsets and different software etc. and so - they will sound different.

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
