Official GB for DSD DAC Signalyst DSCv2

Hi,
Will be available isolator + reclocker for DSC 2.6.2 too?
Click to expand...
At the moment Pavel does not have any plans to release even DSC with a reclocker, as I know. He said only that by the end of the month the prototype will be ready.
No plans for standalone isolator+reclocker for DSC too.

Better to go for BBB i2s?

IMO - yes. With good clocks.
No need to wait Pavel's new design. You can buy it right now - McFIFO/McDualXO or Cronus/Rhea/Hermes combo. These products can be used with ANY I2S DAC.

The only possible advantage of Pavel's approach - it should be cheaper. 🙂
 
A couple of my PCBs, to interface my Twisted Pear Cronus with DSC2, are in the process of being assembled.

DSD data from Cronus to DSC2 and isolated inputs for mute and DSD on.


I'll get the headers soldered up soon and give it a try.

Thanks Vit, i will go fo it 🙂

BBB is on the way.

Hi, any chance to get it? 😛
 
Hi!
As I'm no longer associated with GB in any way, I decided to close this thread. Alexey Galkin (HiddenPilot) asked me to give him 2-3 weeks to open his own GB.

All questions related to technical support and purchase of DSC should be addressed to Alexey directly (PM or post in this thread while available).
 
Thanks a lot, Ray.
I would like to focus on my own DSC related projects (hope for cooperation with Pavel):
1. Supercapacitor power supply for DSC.
2. Takman/Vishay Z-foil resistors for DSC
3. TVC for direct connection DSC to power amplifier (no need in output transformer).
4. BBB replacement with a more compact solution.
It will take time and money. 🙂

That all sounds very interesting Vit and I'll look forward to your developments - hopefully you'll keep posting here for those of us with no Russian language ability.

Thanks a lot for sharing experiences and support.
 
I see JL Sounds has a new version of their I2SoverUSB board available and it now claims to match Amanero by offering DSD512 (in addition to its onboard isolation and rclocking, which already set it apart from Amanero). Looks like another interesting option for getting DSD data to a DSC2 board.


I2SoverUSB - I2S over USB Audio


Will be interesting to see how it works out in practice.
 
Hey guys, can anybody help out with the set up for the 2.6 board with Lundahll 1527XL? The guide really does not talk about 2.6. There are jumpers: J10, J11, J13, and J15, I have 3K3 resistors in place across the transformer outputs, but am not sure what to do with the jumpers for single ended vs. balanced output?
 
Hi Vit, thank you ver much for your enthousiast and friendly support here. So much appreciated!

I haven't installed my dscv252 yet as my hqplayer streamer needs to be finished first and my diy chassis for that takes more time than anticipated (like my family).

I am hoping for a more simple and cheap solution for isolation and reclocking. The JLSounds new usb to I2S looks interesting in that respect. Ty Nautibuoy for your note on that!

Alexey/Vit, is it an idea to end this thread with a last post including the link to your new GB thread?

The same as for 2.5.2 board:
XLR - J10 - 1, J11 - 1, J13 - 0, J15 - 0
RCA - J15 - 0, J11 - 0, J13 - 1, J15 - 1

Yes. If Alexey decides to start new thread - I close this one and post link.

If no - I add info in first message "GB closed, if someone wants to buy, PM to Alexey".
 
seems odd...

With Lundahl 1527XLs in place and no jumpers the DAC is working perfectly, with output voltage of 1.55 V @ 0dB input. Looking at the board it appears the jumpers might only be needed for the Chinese transformers?

Output stage schematics is the same for 2.6.2 and 2.5.2. So, you can use RCA w/o any jumpers soldered.

If you solder J13, J15 for RCA - you connect DAC GND to RCA GND. If no - RCA ground is isolated from DSC GND.

It's true foe any transformers.
 
Thanks for the clarity Vit, and for all of your contributions to this project! Only initial testing now, but first sonic impressions are very impressive and I am very psyched to get this thing optimized!
