NAS-comparison: Synology Diskstation DS211/J + Zyxel NSA-310 + new category + Ünnlink 192 / Part 1

hi there ! 😉 ,

first many greets + sorry for not soo much posting here lately..! 

so,okay, as we have our streamer (see last „projects“) with or without Raspberry Pi´s here, (as said for me „Volumio“ + Bubble UPNP is the best alternative), and we also have now mostly a lot of Android-Devices (SmartTV, Handy,Tablet etc..) we now have to „feed“ them.. 😉  (and at best, „permanent, quiet + energy-efficient“), we have to look at some „Diskstations/NAS-devices“..

I´ve just bought over the last weeks three of them to get into that business in general and to test the usability over all..

First i´ve bought some „Zyxel NSA-310„, 1-bay, e-sata support, cheap, to has a very „rudimentary“/simple interface/gui and i´ve got transfer-rates about 40-50MB/s (Gigabit-network smb) ->got it easy in the network- + u can find it easily with some Android Apps like before mentioned „Bubble UPNP“ or „Mediahouse“ or similar..

but it was for me a little bit to slow/the gui is too simple..

so i´ve bought next some „Synology Diskstation DS211J“ ! ; absolutely in another league/world ! 😉

absolutely great user-interface/Synology-OS („DSM“), absolutely „massive“-options for sychronizing all your cloud-accounts (GDrive,Dropbox,Box etc.), great tools („Audio Station“,“Photo Station“,“Cloud-Sync“,“Media-Server“,“Surveillance-Station“ etc..) + the according Apps (Android/Apple) for it->“DS Audio“,“DS-Video“ etc..

BUT !! : the great downside was the really, really horrible slow hardware !! on this Diskstation(s) !! absolutely slow data-rates (about 40MB/s) + absolutely slow/laggy GUI !!

on these „DS211J“ u can do (honestly said) nothing with it->sooo absolutely slow..

I´ve found then, that are tons of different-versions from these Diskstations-> link see here ->, 

and so i´ve bought another one without the „J“ (junior)(there are 3 classes->“J“, normal, and „+“) and on these „normal“-version (DS211) u can use the station „fairly“..

so conclusion/hint for it/for you: NEVER buy a „J„-model, absolutely horribly slow, almost unusable.. !!

(more in „Part-2“)->(coming)

greets for now !! 😉

Usability / Volumio->BubbleUPnp / Volume-Potentiometer-Hardware-None

so, 😉

sorry for the lately uninteresting/not so „fresh“ news about the ES9038Q2M/ES90xx-chips/boards etc..; maybe that will come back..

today, to keep this blog going, some usability-tricks/tips using a RPI-4B and volumio..->

runs fantastic (imo), is absolutely DSD-capable (remember to use an USB-bridge (XMOS or Anamero) „in-between“ and set volumio on „DSD-direct“,“no mixer“, „no resampling“-> else u wouldn´t get the red/torquise DSD-lock-light on the ES9038Q2Ms..->

by that i´ve tried a lot of dlna-apps for volumio and best for me so far is->BubbleUPnP->LINK

there are millions of other („Mediahouse etc.,etc.,“) but imo, BubbleUPnp correspondends superb with volumio..u can see in BubbleUPnP whats playing, can change the volume via the „normal“ volume-keys and u can also play/send .mp4/.mkvs etc.  to volumio and it plays only the audio/tracks..great ! 😉

by that i´ve bought a 10kohm-poti again (wire-diagramm here->  ) and although we have a web-volumecontrol with a MCP4131 „here“->

i still thought its „usability-wise“ better to use an old-school (analogue) poti but its still the same problem as first: u have only a very short range (i guess 35 degrees) from full to nothing and u have to turn it manually ;-)(but u are nearer on it 😉 )..still doesnt know the right conclusion for me, still in testing 😉 )..

greets for now and more to come !! 😉

Raspi-AK4137 single-HAT for 2/3B/3B+ Pi (30$) ; „Sonore“ ISO2DSD v7

so, 😉
thx to this phenomenal (post) in the>,
we have now here our AK4137 as a single HAT for the Pi !! 😉
as said in earlier posts, we have to improve the signal-quality(lower jitter and so on) over I2S->

it costs only 30 !! $ and u can get it here->LINK
..The main function of this board is to improve the quality of the Raspberry Pi I2S signal and reduce jitter. And make up for the Raspberry Pi I2S output without MCLK! The original I2S output of the Raspberry Pi does not have MCLK and most high-performance DACs require MCLK to work. And the AK4137 reconstruction clock reduces the Raspberry Pi output signal jitter enhancement.
This board supports Raspberry Pi 2B 3B 3B+“..
so, as also posted earlier the AK4137 has 768khz (PCM) + 12.288 MHz DSD and DR: 186dB !!THD+N: -150dB ->AsahiKasei(AKM) datasheet->Link

(u use it between the Pi and our ES9038Q2M for example..a really long explanation on the other functions of this HAT is in the ebay-description above)

by that i came by chance (and according to the previous post) about this „Sonore ISO2DSD„-converter (a GUI for the sacd-ripper) + „Sonore DSD2FLAC„->

u can download both from here:

many greets for now !! 😉

Little (Win)-exkursus -> foobar2000-alternative – Teac Hi-res Editor / ASIO-DSD / Win 384k

so, 😉
by searching for the right settings to play real, native-DSD i came by chance about this tool->TEAC Hi-res-editor (WAV/DSD/DFF)

very interesting was, and thats why i post it here mainly, is because i couldnt play (flacs) above 192khz in VLC for example in Win8.1 (Win10) with the XMOS(Skysong)-USB-bridge and our lovely chinese-sabre-boards (ES90xx..)
i could select 24bit/384khz in sound-properties (XMOS-USB-Audio), could „generate“ a test-tone, but playing flacs in 384khz by example was not possible..
I´ve installed this „Teac-Hi-res-editor“ and surprisingly i had my 384khz (VLC) in Win8.1(Win10) !!
think it had installed some driver from which i was not aware of before..
second, the main very interesting feature of this Teac-Player/Editor that u can select the different DSD-rates (DSD64-2.8M,DSD128-5.6M and DSD256-11.2M) via the „play-frequency“-dropbox and it switches/plays through it->the Skysong(XMOS-USB)-bridge „clacks“-through and changes the LEDs accordingly to it !!

wonderful and absolutely easy !! (i had the ES9018K2M connected and have unfortunately a white noise at these rates (the PCM-rates up to 384khz are working well), but will test it with the ES9028Q2M and the ES9038Q2M)..
anyway, absolutely simple and very prolific !! 😉
(u must change the audio-driver in the audio-driver settings to „ASIO“ of course-> see pictures..but soo easy, great)(if u have no „ASIO->(XMOS USB)“-option try to install the xmos-driver V4.36 or V4.45 again (here singxer/skysong-driverpack))

greets for now !! 😉
