So if the ES8620 is so good, why did the SU-6 go with XMOS?

 

The devil you know, versus...?

What is strange is that intensive Googling and even digging around on ESS Technology's web site yields zero references to an ES8620S USB chip even existing--anywhere other than in the new Gustard U16.  What chip maker produces a significant new piece and does not even have a press release about it?

True. Maybe U16 is like test platform for them before go official  

 

The fact is U16 sounds smoother, liquid comparing to XMOS SU-1. It sounds more like Dante protokole DIO.

Rafa,

 

 The U16 requires special drivers?.  What type of PSU has in it, switch linear?. What clock uses?

 

Thanks. 

[rafa]

Windows 10 installed device automatically. But I used drivers provided anyway.

PSU is linear. Clocks Accusillicone, which is typical for Gustard.

Pictures will tell you most  http://www.erji.net/forum.php?mod=viewthread&tid=2122902

Hello rafa.

 

¿Do you also appreciate a higher resolution and transparency in the sound or is it similar? ¿What DAC are you using?

 

Thank you.

[rafa]

Resolution and transparency is similar and is very good. You wont go further on this. 

I am expecting more hi-end aspects.

 

DAC is in my signature.

 

btw

I started separate thread for U16 

 

[bratsson]

Is it possible to make my sotm sms-200 feed the singxer with dsd512? It's Linux-based OS on the sms-200 so I can't change the singxer drives?

Another new discovery...

 

It's been a short while since I post more findings for SU-1 here, and think it is time to share my latest finding.  I have been making Gotham JSSG360 cables for a while, replaced all DC power supply cables, PC CPU, SATA, and soon 24pin ATX power cables, as well as few other devices internal DC cables with very good success, finally I decided to give SU-1 the same treatment, and the improvement is very noticeable from the moment I power everything back up.  The improvement from this short section of cable is quite surprising, not only the overall detail retrieval took another step forward, sound stage, dynamic, layering all moved up nicely.

 

This cable isn't difficult to replace, and for the amount of additional enjoyment it provided, I would highly recommend to give it a try.

 

Here are couple pictures of this Gotham JSSG360 cable.

 

New cable installed.  Connecting to the 5VDC input:

Hello Elan120,

 

I'm looking for Gotham JSSG360 cables , replacing all DC power supply cables, PC CPU, SATA for my PC, but could not find anywhere. Cn you help? Many Thanks

Hello Tuy,

 

Here is the Gotham cable:  https://gothamcables.com/en/gothamcables/starquad/11301gac41ultrapro

 

I purchased mine from here:  http://gothamaudiousa.com/

 

If you plan on making the cable yourself, getting them from Gotham distributor is great, since you can make custom length and connections.  If you want to purchase ready made, then follow the post above from Ghent, although I have not seen their cable in person, so cannot comment their termination method.

 

I have posted how to make the cable in another thread, let me know if need it.

I'm interested in following your lead and making a Gotham for the internal cable of the SU-1.  Any pointers?  I've previously made a normal DC cable from the DC input to the board connector so I am fairly familiar with what to do in general.

The only pointer is try keeping the shields terminated as close to the connectors as possible to help keeping the RFI exposure to the minimum.  Other than that, if you already have a crimper for the two VHR-2N crimp terminals (pins), it will help make this job quite simple.

 

Another option is...send me your address via PM, and I will make one for you (no cost).  All you have to do is to replace the cable you have and plug this one in.

Could someone please confirm for me that 2018 Singxer SU-1 model has fixed issue compatible with W4S DAC2v2-DSDse.

Thanks!

Hey Snoop, the fix for the SU-1 issue with the W4S DAC2v2-DSDse is a twofold fix:

1) Special firmware that configures the i2s output for W4S

2) Bypass capacitor for PCM selection issue.

Contact [email protected] and he will configure a unit for you. 

See my post here:https://www.computeraudiophile.com/forums/topic/31500-i2s-compatibility-issue-between-w4s-dac2-singxer-su-1-two-beatiful-pieces-of-hi-end-products/?do=findComment&comment=671616

 

[snoopy72]

Franatic,

Thanks for quick respond. I though 2018 model doesn't have same shipset as older model so I have no clue where to install bypass capacitor.

Yes, it may be different for the newer model.....not sure.

He will tell you what you need to do.

[snoopy72]

Will do. Thanks again.

I wrote them an e-mail and got following reply:

--------

Dear Sir,

Thank you for your mail. We are aware that a particular customer in China is using the ES8620 in a new DAC.

This device was originally designed for Soundbar applications and has been non-preferred for new designs for several years.

We do not recommend this device for new designs and we are not supporting it here in Europe.

Sincerely,

David B*****

WOW!

[NoNameNPC]

I read this tread and concluded buy FPCAP (R7) 220μF 6.3V x 5 and SS1117-3.3

Is this good?

But i don't know what caps I must buy for PSU board?

What you suggest?

[NoNameNPC]

Also need SS78XX 5v.

@Energy- can you double-check my Digi-Key part numbers?  

• Nichcon Part #RR70J221MDN1, Digi-Key 493-3705-ND 
• Panasonic Part #EEU-FR1E331B, Digi-Key P15357CT-ND

 

2 Panasonic must be solder near voltage regulator?

If $400 is too expensive for some of you then go for a smaller mod.

 

SU-1 Main Board:

- (3) Nichicon FPCAP (R7) 220μF 6.3V 7mΩ

- (2) Panasonic FR EEU-FR1E331 330μF 25V - 56mΩ (to replace capacitors nearby LD1086 regulator)

- (1) Sparkos Labs SS1117XX Discrete Voltage Regulator 3.3V (to replace LD1086 regulator)

 

SU-1 Power Board:

- (1) Panasonic FR 1000μF 25V 18mΩ

- (3) Panasonic FR 470μF 25V 30mΩ

- (1) Belleson SPZ78 Discrete Voltage Regulator 5V (to replace stock LM2940CT-5)

- (4) WIMA MKP2 0.1µF 100V 5% (to replace film capacitors)

 

Internal Wire Upgrade:

- (1) Canare 4S6 Star Quad Cable 1FT

- (1) VH Series VHR-2N 2 Position Rectangular Housing Connector Receptacle

- (2) VH Series SVH-41T-P1.1 Contact Crimp Socket 16-20 AWG

 

NOTE: Capacitors

* Try to not increase capacitance higher than stock value

* The lower the ESR/Impedance the better (except for electrolytic capacitors nearby the LD1086 regulator)

* Replacing with WIMA MKP2 isn't really needed but if you want to, order everything from Mouser instead

 

The biggest improvement would be feeding the Singxer SU-1 with the cleaner UpTone LPS-1 linear power supply. This bypasses the noisy LM2940CT-5 (150µV) of the stock linear power supply and removes AC leakage loop being sent to the DAC. If one cannot purchase an UpTone LPS-1, then changing to a lower output noise Belleson SPZ78 (4µV) will also yield improvements that are audible. The next upgrade after that would be changing out the LD1086 (100µV) voltage regulator to the discrete SS1117XX (3µV).

 

NOTE: Voltage Regulators

* µV stands for the measurement of output noise in microvolts (the lower the better)

Thanks.

I'm using two identical SU-1 clones (FUN01 V1.1) to do capacitor comparisons and I am wondering what is the lowest voltage capacitor that is safe to use in the positions of the aluminum electrolytics on the SU-1/FUN01? I realize there are more than one version of the SU-1, but please just stick to my question and don't start ranting about why Chinese clones are the devil. 

From what I have read, the voltages are 5-7V, so would a 16V Sanyo OSCON be okay in all 6 positions? One other question, is there any truth in people saying that the capacitor nearest the XMOS has the biggest change? I wouldn't have thought so based on my experimenting, but curious if anyone has a comment on this topic.

I'm comparing against Rubycon BlackGate™ F, Rubycon RX30, Sanyo OSCON, Nichicon Muse, Nichicon Fine Gold, ELNA Cerafine, ELNA SILMIC, ELNA ARS SILMIC Super Gold, ELNA ToneRex, etc.

I had a decent amount of people asking me to test the OSCON series, but it only goes up to 16V from what I found (correct me if I am wrong).

Feel free to come by and check out my site, I'm working on the Potomac AA-51 for getting accurate THD, IMD, Phase and more measurements. I landed on using screw terminals in the capacitor holes and you can get the rest of the details if interested in the link below.

If anyone has any suggestions on how to improve or general feedback/criticism, you can find my contact info on the site or comment at the bottom.


Thanks for any help you can provide!
