Massdrop: SMSL SU-8 Version 2 DAC 200$ Dual ES9038Q2M + Volumio 2.565 (12-03-2019)

so folks 😉 ,
sorry that i lately post so much „massdrop“-related things, but this is first an audio (ESSabre)-site and second heavy related to the ES9038Q2M 😉
as said, DUAL ES9038Q2M on it, some additional specs:
Input: USB, optical, coaxial
Balanced !! Output: RCA, XLR 
USB sampling rate: PCM: 44.1–768 kHz; DSD: 2.28224–22.5792 MHz
200$ (instead of 250$)
(PS.: and btw.: u get 10$ „start“-bonus !! if u join massdrop via these – link(s) (on the site + right via the „widget“(„Xavier“)) !!..
so hop, hop and join !! 😉 )
(„display-wise“ its not soo great, but for all these problems we have here on essabre-90xx-rpi „tons“ of display-tuts and possibilities (for DIY)) 😉

Driver (Shenzhen-Audio) are here (XMOS V4.47)->
and an review is here ->
interesting at this review is the following „SINAD„(some distortion-/noisemeter)-diagram, with some „oppononents“ like Benchmark DAC3, Schiit Modi USB, Chord Mojo, Katana, Auralic Vega and such->

by that some new „Volumio“ is out (now at VERSION: 2.565)->LINK, some fixes, and since V2.527:->Add direct DSD Support to many USB DACs, Mpd 0.20.18 version.. its a little bit on „hold“, just ordered (as said before) some Burson V5i-D and can then report about the Op-Amp and the „general“-massdrop-experience..

greets from here for now and stay tuned !! 😉

Absolutely simple Arduino IR-repeater for Hi-Fi Gear Cambridge Audio CA-540A or other..

so, 😉
after i´ve made some IR-Remote substitutions for my Cambridge Audio CA540 Azur Amp (see „Project-1“ and „Project-2“ and so on) here on the site with first Bluetooth and then Web-Control i´ve finally made it „over-simple“ 😉 and use an Arduino (2,50$) + some IR-receiver (VS1838B)(0,40$) + IR-Transmitter (0,40€) + some dupont-cable (also 0,50$ incl.shipping)->on aliexpress by example..->Link,Link,Link


the point was the right library for this and i used (many,many thx to „Eddy Yanto“ !!) the simple IR-repeater-library on github->
point was that in description it says:“..This sketch receives the infrared signal on standard pin number 3, decodes and dump the infrared information on Serial and forward the raw infrared signal to pin number 4.“; but that works not !!
in the .ino on the other hand it says:“ RECV_PIN = 4;
IRrecv irrecv(RECV_PIN);
IRsend irsend; // Defaults to pin 3“ and thats the opposite !! (works with the .ino-settings now of course)..
tried to reach him via e-mail to correct the description->no success until now..
anyway, u can now use almost any (hi-fi)-remote; place the ir-receiver at some point near u (and to which your remote can point/send to of course), make a dupont-cable-connection to your arduino in any length u wish and from there also in any length to the ir-transmitter !!
(the sketch only receives + transmit->no more other modifications to do in the sketch !! (noob-friendly 😉 )
easy as this and thats it ! 😉 (Total costs: 4$)
(working sketch is here btw.->Link) and on Github of course, again->
by that i´ve bought some Burson V5i as D (Dual) and will report then about it !!

greets for now 😉

New XMOS-USB-Driver (Skysong/Singxer) -> v4.59.0_2019-02-13 + Massdrop ES9038Pro

hi there, 😉
found by chance on then shenzhenaudio-website this new XMOS-USB-driver V4.59 (02/13/2019) originally for the Singxer SU1/SU6;
tested here with with the Skysong(Singxer)-XMOS-USB-device (XU208)(+ES9038Q2M) on Win10 -> works fine !!

by that there is some Dual !! ES9038PRO on Massdrop->

->Dynamic range: 131 dB
USB: PCM 44.1, 48, 88.2, 96, 176.4, 192, 352.8, 384, 705.6, 768 kHz

interesting is the separation from the device + power supply..
it is the same principle as maybe earlier with the Mission Cyrus Amps 1-3 with an extra PSX which cost the same !! (and i had luckily here) and which remind us of the great importance of a clean, strong power supply !!

Massdrop: Burson V5i ->Dual !! 24,99$ (Single matched pair +15$)

so folks 😉,
sorry that i had lately not the time (and fun) to write here any further posts (+ time is changing here so fast concerning Pi-audio-distros and so on etc.); also i have to buy here some things first to post here more about „modding“ the ES9038Q2Ms..
but i found here right now an interesting offer by „Massdrop„-> some

BURSON V5i as single or dual !! ( Dual!! 24,99$ (or Single matched pair +15$)

so great !! 😉


hopp,hopp and get some !!!  😉

only 4 Days left !! (Drop is till March 24. 2019)

greets for now !! 😉 / registering not possible at present..

so folks, 😉
sorry about it; but „registering“ is not possible at present; but u can still leave some comments via the comment-„button“..
by that i/we have a great „hack-attack“ and so i have to delete a really great amount of „false-user“; it could be possible that your account will be deleted too..
i inform u if registering is functional again..
by that, outgoing mail is also not possible at present (for password-resetting and so on)..i work on it, but it can last a little bit longer..
kindly excuse any inconvenience !!

greets for now !! 😉

Little update: Skysong XMOS-USB-Bridge external power supply 5V / interesting discussion „real“ DoP

so my dear visitors, 😉
after this little site got so much resonance (which i never expected) and i finally found the „real“ reason for the stuttering in my Skysong-XMOS-USB-Bridge – ES9038Q2M combo->it was the power-supply (more shortly) and i have got now such a wonderful/brilliant sound here + a very interesting discussion/topic was coming up concerning „real“ DoP (DSD) on the Sabre-boards with the „DSD-lock-light „ON„, i thought i maybe make a new post..
and excuse me, its all very „repeating“ here on the blog (said it before), but its a blog, with a little „Life-line“ and so we have to live with it 😉 ..
back to the first topic: as said in this post->>“ that to provide the Skysong/Singxer USB-bridge with an external 5V power supply also boosted the overall performance of the Bridge by 10-15% !! absolutely to recommend !!..“ i had lately this „stuttering“ on the combo again, thought first the ESS-PCB/-chip is damaged, had not enough power etc.. but at present it looks like the wonderful,wonderful usb-bridge is getting a little bit older, and a few days ago in searching for the reason i plugged again the external 5V power supply in and hooray: the stuttering was gone and the tune/sound really improved again, so great, the positioning, the absolutely more exactly tone and so on !!
really,really wonderful bridge !!

(i´ve got the luck that i´ve got the „deluxe“-version with the golden Crystek + some other modifications; absolutely superb !! i´ve read somewhere else that the skysong-bridges are the ones with the „finest“ xmos-implementation and so on..i can absolutely confirm it from here !!)

the interesting thing is now that i was/am an absolutely Raspberry Pi-I2S-ESS Sabre-board fan/defender, absolutely superb sound, absolutely jitterless and so on (in comparison to any PC-soundcards or other DACs etc.) i must say, that such a combo with this skysong-bridge + nowadays USB3.0 (which had also a great effect on the „tune“ here (vs. the old USB2.0)) is really close/tight to it !!
it is an absolutely improvement via USB3.0 + some external power supply (as said), really close to some Raspberry Pi->I2S connection..

by that „Johnson Wu“ had a very interesting question (here in the comment-section on the right) concerning real „DoP“(DSD) sound with DSD-lock-light ON on the Essabre-boards->look at the comments on the right (or at the bottom of this post->

more to come,many greets for now !! 😉

The AD797BRZ arrived -> more „dark“-sound, more in the back/laid-back..

so, 😉
finally the AD797BRZ arrived here (all following is under the „premise“ that i´ve got original (or near to) ones and not cheap „crap“)->absolutely more „dark sound“, absolutely more push in the lows/middle-lows..
(as presumed->“the BRZ were the ANZ with all the advantages of an OPA627AU..“,“its like going from digital to vinyl“..)..
absolutely okay, high THD+N, very „exactly“ , very good Op-Amp, but for me absolutely too dark, not soo much presence (at all and in the middle-highs/highs..)..

(but also said: i have got not the time (and fun) at present to get more in-depth with the BRZs)
after replacing them with the ANZs:->thats for me the right direction..
get so a better idea of the „true/right“ sound..(for me)
(i really miss the „brilliance“ of the AD797ANZ (in any case from the ones i have here)(although, as said, i also miss the „push“ in the low/middle-lows))..
but all this depends very much on your other „gear“, speaker, amplifier, room-size, listen-preferences and so on..
so, conclusion:
i will stuck here with the AD797ANZ for now (on the „blue“ ES9038Q2M)(all according to, as said, that i´ve got the original (or near to) OP-Amps..; i would prefer them over the NE5532,LME47920,OPA2134,LME47910,Muses8920,OPA627AU->(in this order)(see this post in the forum->LINK)
but again: it really depends on your personal listen-affections and so on..
in optimizing the ES9038Q2M the next steps will be (without some hw-modding;its too complicated for me at present): connect a -+15V toroidal transformer, buy some (as last op-amp-step) Burson V5/6 and maybe use an AK4137 (see earlier posts)..
and („quelle surprise“): buy finally some new speaker+amplifier 😉

but many greets for now (+ more to come)!! 😉
