bratsson Posted August 9, 2019 Share Posted August 9, 2019 Have anyone managed to get DSD512 work on the SU-1 feeding it from a SOtM SMS-200? I can choose dsd512 in settings but then there is only silence when playing but DSD256 works great. Link to comment

Start it while SU-1 is connected to the PC, and it will display the current firmware version near the top. Which program do you refer to to flash new firmware? Link to comment

It’s been a few years since I’ve used it...here’s a post that describes what to do, just use the latest firmware for SU-1: -Paul DeltaWave, DISTORT, Earful, PKHarmonic, new: Multitone Analyzer Link to comment

LoryWiv Posted July 15, 2020 Share Posted July 15, 2020 I have developed annoying background hiss somewhere in my chain that is hard to diagnose. I am considering trying to reduce USB noise from the PC by adding an iFi iSilencer between PC USB out and SU-1 USB in. My question is whether the SU-1 itself would be expected to reduce USB noise from the PC input before data signal is output I2S to my DAC, in which case iSilencer before the SU-1 is redundant. Alternatively, if the SU-1 does jitter reduction, reclocking etc... but nothing to reduce USB bus noise originating from the PC, iSilencer may be worth a try. Thoughts / recommendations appreciated.

Duy Le Posted December 23, 2020 Share Posted December 23, 2020 This is the final mod (USB side) for my SU-1. I used the board of HNE-labs (built with LT3045), clock Crystek 575-25 24000MHz. USB signal/power is provided by BeagleBone Black (industry version), it is the rerender instead of PC/laptop. R1200CL 1 Link to comment

Sounds really nice, an obvious, although not huge improvement. Later in the day, I found my Sparkos Labs SS1117xx regulator in the mail. I went ahead and unsoldered LD1086 without problems. I cheated and got a rework workstation with a hot air gun -- makes unsoldering SMD components really easy! My excuse was that I needed a new soldering iron anyway, and this workstation was only $59 I then carefully bent the SS1117xx regulator legs, making sure that the pins were aligned correctly and used the soldering iron to fix it in place. This actually was a bit trickier to do, as there is little room to work in between Sparkos and the PCB and I didn't take the PCB out of the SU-1 case. Tried this out in my system, and it really was as everyone said: the change is not subtle! I'm still using the iFi 5v supply, so perhaps the change would be less obvious with an LPS-1. But for me, it's a major step up in SQ. If the change from DSD256 to 512 was about 5% improvement in SQ, the relative change to Sparkos 3.3v regulator was closer to 20%. I'm not kidding! The bass became a lot punchier -- almost visceral, like I added a subwoofer. The air around instruments became more obvious, all the sounds seemed natural. On a good recording, there was nothing I could hear that didn't feel just right. I'm sure I'll discover more things I need to improve later , but for now, I'm a happy camper. Thanks to everyone who recommended and explained this mod in detail, it really was worth doing it! I know this was a long time ago, but do remember the procedure to update the Singxer SU-1 firmware. I have downloaded the latest drivers 5.58 already and installed them. Link to comment
