SU-1 it does is very sensitive for power supply quality. Any small change is easy to hear.
I am not either, but do have the same combo SU-1/Spring LTE3 as yours, and in my case, it was a good degree of improvement using LPS-1 to power the SU-1.
OK. Convinced. Ordered the kit. Thanks everybody
I just took a week+ vacation from my su-1 kte and reintroduced it into my chain so I could get fresh ears to know how much it really enhances things.. long story short... a lot!
I noticed a very significant improvement over the HD Plex linear power supply I was using. You wont be disappointed.
Are the eBay SU-1's the same as the ones sold by Shenzhen audio?
Is the below link the item I need to convert the SU-1 so it can use an uptone LPS-1 as its power?
Anyone know of a Y-cable? To connect both the SU-1 and a uptone ISO regen to the same LPS-1?
1 - It depends. I bought mine from eBay China seller. Other than taking him 5 days to ship it, it was fine and genuine. Once shipped, it was extremely fast via DHL
2 - Yes
3 - Plenty available. https://www.amazon.com/gp/product/B007Q8IKRE/
I was pleased to learn that the SU-1 firmware update is available to support native DSD512. The version 2.22 FW is for PS Audio / Matrix, according to Singxer. However, I have upgraded firmware to 2.22 but output from HQ Player using the XMOS ASIO driver still only allows DoP to DSD256!
I have the Singxer SU-1 with all jumpers set to off (Matrix / PS Audio standard), connected via USB to my Windows 10 computer, I2S output from the SU-1 to a Matrix X-Sabre Pro which is capable of native DSD512, but still only DoP 256.
Is there something else I need to do?
Please post screenshots of your HQP settings page and the main screen.
Thanks Tboooe. In the 1st screenshot if I change SDM pack setting to DoP and bitrate to 44.1k x 256 I can output DSD, just as before the firmware update. However, my goal with FW 2.22 was to get support for native DSD512 as the FW notes indicate it is capable of (and my DAC supports), and on that I am stymied.
Thanks for any help!
Issue of firmware update not providing native DSD512 support solved. See https://www.computeraudiophile.com/...-the-singxer-su-1-ddc/?page=13#comment-661103
Glad it got sorted. I was going to recommend using the alternative driver. So the real question is....how does it sound???
yeah is it just dsd512 or did they optimize the code for sound improvements too? I'm gonna wait a week before installing just in case the firmware has problems
As I understand its code to allow native DSD512. I've been running it for over a week now with no issues. I say go for it!!!
How difficult is it to install that mod?
Does the power receptacle plate on the SU-1 just come off when you unscrew the cover? Is the connection soldered to anything?
