no. the best option is 16 44.1 909/990 (from 16/32 float direct 44.1 player output)

better than v5i-d or sparkos)

To everyone disappointed in ROHM module - AKM is a must-have for purchase. corrects ESS jambs (except for turbo whistling in normal/eco) and does not chew frequencies like rohm. top, especially with its special filter - 5 or 6) super slow suited me perfectly + norm gain + 4.4. tested with...

xduoo support corrected the description for digital filters for ESS 9039

File with a metal nail file for 5-10 minutes, there are photos and manuals in the thread. the bridges that I ordered were suitable for simple opamp and xduoo opamp module, but not with Sparkos, perhaps I was unlucky - they did not connect completely...

However, the support turned out to be useful, filters 5 and 6 were duplicated in AKM, ess - a false table from 9038.

lol, just looked at the AKM table) fir5/6...

I received a list of filters from xduoo support. I don’t believe that their engineers were able to redo not only the order, but also return the old filters to the 9039pro. most likely the support was given old data, from the time when they wanted to release xd05pro with 9038pro (yes, in the...

lol, I received a response from support. they only threw off the ess, drum roll - they threw off the information from the old DACs, in 9039 about there are already different filters and order in the datatsheet, they definitely couldn’t redo it, the support mixed up / has no knowledge about the...

sparkos don't make noise, rly)

This is already arrogance, they were too lazy to write the names of the filters in the firmware, they did not post the pdf/datasheet on the website, they did not describe all the filters anywhere. Even in the box with individual DAC modules they don’t put a sheet of paper with the names of the...

and R2R)

which fir filter did you use on ess? if you have time, please take measurements for fir 1 (new minimal linear), fir 4 (linear slow) and fir 7 (new minimal slow) separately, thx.

about hum... on the battery, linear charging from the router and on the ifi elite, I don’t hear any noise with low-impedance iems at 18 ohms in turbo mode. unlike xd05-bal, where everything was noisy. in xd05pro there is noise in pauses or in YouTube silent video, there is audible noise for 1-2...

I used v5i-d in xd05-bal before, I bought other op-amps - all were flat and simple, some were cleaner, some brought in some goodies, but it was the burson that gave the wow 3D effect + pleasant enhancement of low frequencies. I tried v5i-d with xd05pro, I liked it, it’s better than stock, but...

try fir 7, this one boosts low frequencies on ess fir 1 - Lots of detail and stage, good mids, but drowns out the lows fir 4 - also emphasizes low frequencies, but less than 7, but definitely nothing will hurt your ears at the top (at 7 the version is a little brighter and sharper, but not on...

from the point of view of “selling more extras,” it would be better if they released the xd05pro with rohm and sold the 9039pro separately, thanks to them for not thinking of that)

don’t waste money on a boring and simple rohm dac module, I managed to listen to it for half an hour or an hour (16 44.1), then I got tired of it, put it in a box anyway and use the more technical ess9039pro. if the high frequencies tire you, try 7 (new slow minimal) and 4 (linear slow) fir...
