Evolution of value SD Memory Player

The world's best DAC "Ess's" ES9018 "" (sampling frequency 352.8KHz 32Bit) using the "SD player" to introduce, went further and upgrade the power supply.



Yesterday, after a long time "Bunpei's" is "a new SD player" appeared to carry.
This player is part of the thorough streamlining supply, display selection, we add the switch is subjected to the operation.



"Digital Display"
Left in front of the SD memory card is inserted.



"SD player's entire system,"
Previously "ES9018" DAC to R L 8ch one each side but the parallel specification, so sacrilegious "ES9018" for single use.
Start playing the clock is also fitted with an extra 90,000 yen each.
(Battery power is used to bias the clock)

This is the tone I was really surprised. w (o゚゚) w!
CD source is extracted from the rich as if hearing the master tape though, and spread of the sound of the bass in, good localization is, of course, mechanical digital can be expressed as the music the music so far is not speak.

Repeated remodeling was completed a thorough study of the circuit, "mechanical" dream it.
CD, LP, hard drive, they have to rotate and read, SD memory players do not need it.
Without skipping data, reliable information systems can play, I feel a new era of music playback.

I asked for the production of a new drive mechanism immediately, in late January next year will be unveiled to everyone as possible.
Unfortunately, DAC "ES9018" heightened global assessment, is available in short supply of nowhere in sight.
Those who wish to manufacture a new SD player, I would be asked to wait.




SD is the dawn of the new digital drive mechanisms!



"SD playback system completed"
SD new drive mechanism, playing with display panels that feature selection is added to the feed folder.
Power circuit has been enhanced, significantly improved the ability to play "master tape" It is impressive richness of sound like you're listening to.



When I listen to than in Haisanpuringusofuto "352.8KHz 24Bit" can be seen in the musical shadows and fine detailing.



"176.4KHz 32Bit" provides an uplifting feeling comes out.
Both delicate and wonderful, dynamic, fun comes out more and more original music.

Makoto Sako LP while record by the large amount of information, CD player, such as not skipping.
Unlike vinyl and CD information from the feed, such as a rotating body, and the good localization of the sound was great stability is remarkable.
Generation digital sound so good, wonder if we just taste good, seemingly without a great shame!



"Strengthening the Power"
Made a second-generation power rectifier power transformers FINEMET Degawa, if enhanced by excellent phase characteristics of the film capacitor audio band also sense of depth of sound, brilliant sound will begin playing.
I think it is establishing a new direction for digital playback in the future.

Bunpei's proposal, DAC except the transistor amplifier output and try to listen to the sound input directly Akutibufeda turned out to be a wonderfully pure sound.
Unfortunately this method, DAC has a weakness for small to represent the low frequency output, or vacuum tube amplifier, in transformers or FINEMET out, also found that it improves sound quality from the current number of stages.

Otherwise Feastrex taste, while listening to the bliss, looking for the ultimate sound further challenge is not inexhaustible.

T , do you now where the main board is sourced from?
Listening with my ears :)

Hi Tuyen,

If you do drop a line to them would you be so kind to ask about the clock...just the make and what sort of mods (roughly)....to get it going ;)

Hal did not answer back (yet).

Regards
Erik

Hi G,

its designed by a guy on diyaudio called Bunpei.

Link to the thread on diyaudio here:

Could always drop a pm to Bunpei to see if you are interested.

Cheers
Tuyen
Cheers T , sooooooo many choices these day's my head hurts :)
