Different filter types->ES9038Q2M + other..

so, 😉
because i´ve got now the possibility to change the 7 different-filters „on the fly“ (on the ES9038Q2M), means no annoying jumper settings, and via BT or web-control, i can say/state a little bit to my impressions about it:

I tested it via jumper (manually) a few weeks ago and at that time i´ve got the feel that it makes a huge difference, up about to 20%, and i really loved the „linear phase fast roll-off filter“ (JP3+JP6)..
but, now, yesterday, i didnt feel it was such a huge difference, only about to 1-2% !! the other „circumstances“, quality of the source, the right op-amp, the quality of the power-supply (15V and or +/- 15V) have absolutely a really greater impact of the sound/tune..
The filter here on the ES9038 are really on the digital/sample-site, there is no more 3D, spacious or something and had almost no effect on the „true original“-tune..
if u really like the bitperfect, faithful, „true to original“ tune, u have to improve your hi-fi in another place..
with the different filter u hear something more expressed (or decreased) but the overall „sound/tune“ stays the same..
so, in this case, i/u have to work more on the power-supply-side, onboard voltage supply on these Chinese-ES9038Q2-boards/cable/source-material and so on (as said).
On the other hand are there a few differences in the „sound/tune“->here is a very interesting picture from stereo.net.au->https://www.stereo.net.au/forums/topic/81435-ak4490eq-filter-adjustment/, its about filter settings on an AK4490EQ, but the basics are the same..(i´ve also posted a few month ago an article about different-filter-types and the impact on the sabres from resonessence-labs („Invicta-Mirus“)->

and i got/have almost the exact feel about it !!

very interesting is also this „Sound Source Positioning“->had the exact impression in changing from one filter to another->also thought „..this voice/guitar/something is more in the back or in the front..“ and so on (normal hi-fi experience) !!
Summary: u can hear/have differences, the filter on this board have not soo much impact (imo), but also try to improve your hi-fi in another place !!
