None that I know of, hence I still won't recommend it.

Here is a picture of UAPP upsampling to 768kHz to FC6, so yes, it can do it. However, Windows internal audio driver can only do 384kHz so that's why you are not getting 768kHz unless you have the right driver (ASIO maybe? I am not sure).

Kinda still waiting for its app to release for the full experience. It was supposed to be released in May but said to have stuck on app store approval. Firmware has been updated at least twice since released.

DSD is generally not going to be outputed natively unless you setup direct DSD output or DSD-over-PCM (DoP) on the source - so yes, you will most likely be getting PCM as most music playback app that can decode DSD will (and usually do) transcodes it to PCM first for max compatibility. For...

...automatically between those two depends what data is sent to the chip and requires no extra input from the user. Only specialized DAC like R-2R (*only decode PCM) or 1-bits (*only decodes DSD) will need extra processing before the DAC section to handle / transcode data that they can't handle...

You can't put EQ on Go Blu itself, but there's nothing to stop you using EQ app on your smartphone or laptop.

I don't have any pop/click issue with my W4, but I'll suggest you to try your W4 on different OS devices to see if the problem persists. For example, Android or Windows (if you are using Mac). While you at it, might as well also try different USB cable.

Now it is completed.

That's not the firmware for DC03Pro. That's just the Window's USB driver and most of the time you don't really need to install it for DC03pro to work as it should have been auto-detected by Windows and use Windows internal driver instead.

If you referring to the digital filters (Minimal Phase, Fast, Slow, etc) - those can't be disabled. They are part of the ESS DAC chips internal oversampling process for decoding digital signal to analog sound. You can only pick which to use, but there is no option to bypass it.

Yes, iPhone are notorious for limiting the power supplied over its Lightning connector (Type C iPhone usually have much less of such issue as Apple needs to adhere to USB standard). For example, most Lightning iPhone limits output voltage to around only 3.3V (as opposed to 5V in USB). Sometimes...

Yes and No. Yes as in you can use X7s as a pre-amp to SP200 without causing any fire/explosion. No as in you might not be getting any of the 'Class A sound' from X7s. Class A means the amp section is running in Class A mode, but given you are using it as a pre-amp, where the analog music...

Some power banks have 'smart' port that can detect what is being connected and tried to enable fast charging (namely Power Delivery or Qualcomm QC), which can interfere with USB dongles.

My magic stickers can make anything Hires in a jiffy.

Having owned both W4 and DC-Elite, I too find that neither one really beats the other. Sure there is some difference in their sound signature, but it is more of an issue of presentation style rather than any technical superiority. There are certain aspects that DC-Elite are better at, and the...

Do a battery runtime test. This is the listed spec: Playback Time about 12hours (Standard : FLAC, 16bit, 44.1kHz, Vol.50, LCD Off, Normal Gain) Uses a 16 ohm headphone to run the test and see if you can get at least 10hrs out of it. If you still get much less, then Ill suggest you contact...

Skip the E6, perhaps find something a decade more advanced.

I am not an Apple Music user so this could be wrong - there is a difference between a streaming app ability to stream Hi-res music directly to a smartphone's hardware (aka native playback) and its ability to output Hi-res music over USB. The latter will require the app has an USB output driver...

Not really. IEM profiles are supported since the original W1 / W2 series. It is under 'SDF' setting.

Definitely do an update, there are quite a few bugs in the older firmware.

My first impression is here: https://www.head-fi.org/threads/the-tws-neckband-bt-cable-adapter-thread.920709/post-18086829

Moondrop EVO is in, so here is some first impression: 1) Case is big, bigger than iFi Go Pod. 2) BT connection is not particularly stable, even when running on SBC mode. Likely an issue of early firmware and can be remedied by firmware update. 3) Shallow 2 pins don't fit my deeper 2 pins...

Last I checked I think only iPhone with Type C port can powered the KA17 desktop mode without external power.

Should get mine in less than a week, will share my impression then.

Moondrop released EVO, priced around US$70 or so.
