Sorry I've read this page and 1st page only: is this working now and is it available?
Will it allow me to play DSD from cf card on b-III?
How much does/will it cost?

Thanks

Hi, ccclapp,

We are now announcing an estimate by private usual e-mail.
Please send an e-mail to my following address;
bunpei<at>ta2<dot>so-net<dot>ne<do>jp

The transport does not support a CF card but (micro)SD/(micro)SDHC memory card.
You can connect your TPA Buffalo III to our player and play DSD64,128,256 DFF audio sources.

Default Announce of SDTrans and its options

To existing SDTrans users and to those whom interested in the kit

I think I almost completed sending price estimates or replies to those who sent me their inquiry e-mails.
If you have not received any e-mail from Bunpei, please send a requesting e-mail again.

I have already shipped option 1, upgraded EEPROM for FPGA configuration, to some users. I hope they will kindly post their reports on this thread.

As for the new batch of the board kit, we hopefully ship them within 10 days.
(I have not received them from Chiaki.)

As for the option 3, sync oscillators sub boards option for ES9018 DAC, neither its possible delivery date or cost is not finalized yet. We are just accepting its reservations.

4. Galvanic isolation between transport and DAC

Between the two sub boards on the SDTrans384 transport side and ES9018-based DAC side, I2S/DSD signals are sent from the transport side to the DAC side and a synchronous master clock signal is sent from the DAC side to the transport side. All these signals are isolated by using TI ISO7241 chip. Those signal level is LVDS and connected through HDMI type connectors & cable.

Hi Bunpei,

Is there any chance for me to get the kit from the current batch or I will have to wait for the next one? :-)

^o^

We can assign a few for you if you send me an ordering e-mail.

5. Effect of "Synchronous master clocking" for ES9018

All the people those who has listened to actual sounds based on the synchronous master clocking replied, "This is distinctively better."

My personal impressions are;
1. More finely focused sound image
2. Natural bass enhancement
3. Less digital, more analog feature

I guess the reasons why we recognize such improvements are;
A. Usual asynchronous master clocking of ES9018 DAC chip can't avoid the quantization errors in time domain, maximum 10 ns (at 100MHz clock).
B. The synchronous clocking can eliminate the quantization error completely.

However, in this scheme we must remember that the master clock must be of the best quality.
