native (raw) dsd playback

native (raw) dsd playback

after ripping some SACDs, i can now play some native dsd files using a computer.


the new interface card (still under development),




the player software which read and stream raw dsd file,




note the sample format which states, 2822400 MHz sample rate / 1 bit data / 2 channel

but this thing would not be available until this fall, still working hard with some overseas programmer for application development.

stay tuned.

the sacd ripped and played shown in the above player screenshot,

a rough estimation, about 40MB per minute

it's just about the same for 192k wav file anyway ............

come on, disk space is so cheap nowadays.

Why there is no mac version of the streaming program....
i'm now testing the "beta" version of DSD player application for Mac OS X ...... 80% done.

we are almost there.

another good news is, the original USB interface is now capable of streaming DSD and PCM (with firmware update and new DSD ASIO driver), no new hardware required.

moreover, with the help of a new "plug-in", you can play native DSD using Foobar2000 as well.

if no DSD hardware present, DSD playback will be converted to PCM :

dear mac user,

native DSD playback will be ready for you after 24/Sept/2011, let's start the countdown .........

remember ESS9018 accepts DSD input but doing DSD to PCM inside ...........

TOP

each ESS9018 has 8 dac inside, it is mainly for multi-channel application.

BII has 4 dac elements paralleled for each channel while BIII can use these 8 dac elements individually for a max of 8-channel application.

so basically they are just the same.

just did a vinyl rip (DSD recording) using my Korg recorder.

the result is ok but not great owing to the crappy A/D converter inside the Korg MR-1.

the dac used in the prototype is CS4398 from Crystal (Cirrus Logic).

the USB interface with DSD support (DSD64, DSD128) and PCM (up to 384k/32 bit) is currently cost US$399.

Permalloy合金是不是很贵?
yes, it cost more than usual transformer.

this is another output transformer called "FineMet", it's an amorphous core developed by Hitachi. they are even more expensive........
it is located in the upper left corner of the photo.




you can also see the DAC module is now shielded by mu-metal sheet. the user reported that it is 2dB more quiet with the shield.

I can't tell how they sound because this setup is in the USA.

well, computer DSD playback is really started to blossom.
