Skysong ES9038Q2M / very handy..

4 Kommentare

so, 😉

finally (and last for this), the Skysong ES9038Q2M with display and voltage-poti arrived today (see post before)->http://essabre-90xx-rpi.sfb2.com/?p=2768 ->

meanwhile i can´t determine exactly the differences between the ES9038Q2Ms like this Skysong and some green SMPCB V1.07, cause they “sound” almost exactly the same (maybe these Skysongs are a little bit more “warm” and not so “crispy” like the SMPCB-versions of it (its the same with the Skysong-XMOS-Bridge) , but can´t say this for absolutely sure..

anyway, a real improvement in sound/SQ on these boards is to use a dual-DC -power-supply chain (with +-15V !!) (also see posts before), i would tell it like so (and come to an end with these ES9038Q2M-chinese-boards) (but its very “speculative”, only some guess/feel by myself 😉 ):

  1. 100% -> SMPCB V1.07 (Green) with Dual-DC +-15V
  2. 98%    ->Skysong ES9038Q2M with Dual-DC +-15V
  3. 82%    ->both boards with Dual DC +-12V
  4. 72%    ->SMPCB V1.07 (Green) with single 12V/15V
  5. 70% 😉 ->Skysong ES9038Q2M with single 12V/15V
  6. 68%     -> “Blue” ES9038Q2M with single 12V/15V

but as said, very “speculative” 😉

by that these new Skysong ES9038Q2M with the display, volume-poti and possibility to “control” it via some cheap (3$) Apple-TV-remote is very “handy” usability-wise; very nice to adjust the volume on the board too (its a “hardware”-volume mixer (bit-wise)) and has very little impact on the sound-quality, almost nothing..(by that i can finally change the different filter-types “on the fly”, will maybe post a little bit more of it) as originally wanted here on the site..

so again, sorry about it, but i guess thats the final post concerning the differences on these ES9038Q2Ms, maybe we´ll get some ES9038 Pro in future 😉 ,

greets for now 😉
