Likely a CWOT. Unless there is a reason that you expect this superb product to be deficient in those areas, I would rather see Amir spend his time testing some of the many other pieces of hardware in his queue.

Unless, of course, you go to Patreon and contribute a couple of thousand dollars as incentive for superfluous testing.

Amir obviously spends a lot of time at this "hobby" of his, which I appreciate immensely.
I have what I like to call measurement fever, need to an excuse to sell it and buy something else for measurement :p

Given the 9038PRO part itself is spec'd at 122dB THD+N it would seem the spit and polish, literally, may work just as well as other tricks.

At this level, it's really just about tricks. Can always reduce noise by paralleling, and for distortion just fine tune the thd compensation.

The third harmonic is landing on 60 Hz mains frequency here so that is probably not the right harmonic distortion level.
LOL... I should have realized that! Thanks, Amir.

I doubt Okto will add another ESS chip. They did say the extra channels are paralleled in the Stereo version, but Matrix probably did the same. I guess we'll just have to wait and see.

Yeah so in the end there should be virtually no difference.

This is what Okto is currently publishing and they said they have a surprise coming.

0.000032% / -130dB full-scale THD (Total Harmonic Distortion)

0.0001% / -120dB full-scale THD+N (Total Harmonic Distortion + Noise)

131dBA dynamic range

0.00022% / -113dB THD+N @ 100mW into 32 Ohms headphone output

We have probably reached the end in audible performance in the new DAC chips like 9038PRO, I would rather have ESS focus on improving the filters, and modulator, currently software filters still technically do a much better job, and in some cases it could be audible.
@amirm have you ever thought about measuring stuff using HQplayer upsampling, I remember you said awhile ago that you thought about doing it.

The element P is interesting as well. I know its a different product, with a built in amp, but I'd love to know if the streamer section is the same as the M.

Also, your site rates it as 110 watts into 8Ω with 1% THD. Do you have the wattage rating at .1% THD?
Hello, the streamer/audio player section of element X, element P and element M are all based on the same hardware (ARM CPU) and the same firmware.

Sorry i have no such specs. the current posted specs are come from ICEpower official. we have no necessary measurement filter, so we could not test this specs.

Any chance of Chromecast built-in on current or future products? Many of us appreciate the framework's ease of use, widespread support, and power saving mode of operation when using mobile devices as remote controllers. You're giving Apple some love in form of AirPlay support, which is a battery drain on their mobile devices. So how about Google, too? :cool:

I am trying this indeed. hope we can implement Google cast into element X and other element family members smoothly. Please note, I am a big Google fan. ;)

This video introduces hybrid volume control detailed. just for your reference.
Thanks, but I'm looking for test results. Would also be nice to have comparisons with non-hybrid volume control of Topping, SMSL, Benchmark, etc.
