I don’t have enough history to assess how the mods manage this subforum. However, in other parts of Head-Fi, if one post contains a hint of what looks to be science, it is unceremoniously flagged and the poster is directed toward the science subforum… Ok… except members here still have to deal...

Zero2, Tanchjim’s Zero / One / Tanya, KZ Castor… I use the DSP version of the Tanchjim’s (also have the 3.5mm), and use Zero2 + Moondrop CDSP or FreeDSP cable. Can’t stop playing with these: listening to what’s different, and trying to figure out why, and what PEQ(s) would that be…

Second that. I also have 3x 5K and 1x T71 (and several PEQ-enabled cables for my IEMs). I have limited experience with FiiO products: like the HW… not impressed by the SW. I also agree that support is one area Qudelix could improve a lot. The 5K (and T71!) is great, but can quickly become...

Interesting… if my machine translation is correct, this may be a Moondrop problem in the end, but some of the SRC bypass issues are caused by “unexpected” behaviors of PowerAmp (forcing some Android default settings that then affect every app) and HiBy music (using features from a different...

Do you mind sharing what bug you reported exactly? My take from this thread is there are volume “bugs” that are not bugs…

Good one !!!:beerchug::beerchug::beerchug: That being said… if one is willing to procure a second battery to replace the original, then one should not worry about all of these questions: just replace the battery when it’s dead [issue solved] :ksc75smile:

I don’t think it’s possible… Darwin is the code name for HiBy’s proprietary R2R architecture. The R4 uses traditional DAC chips instead: the (ESS) ES9018C2M chips instead of (R2R) discrete components. Two fundamentally different architectures.

In addition to @Joe Bloggs questions, could you explain what you mean by “Apple Lossless tunes from my collection of burned CD’s”: were those tracks already in Apple Lossless format (ALAC) on your burned CDs? …or did you get Apple Lossless format tracks through Apple Music match feature, but...

I just received my R4 and did some tests with the 'Device Info HW' app listed in a post above. I played an album through HiBy Music, with no PEQ, MSEB, or Plugin active. I then did the same thing with a system-wide PEQ filter (low-shelf), MSEB active (overall temp. slightly darker), and DRX10K...

I’m sure It’s not going to help, but the backplate falling off is most likely a consequence of a bad battery: the battery bulged, maybe not that much, but enough to push the backplate out. It’s actually a pretty good & safe design, you know for sure that something is wrong with the battery by...

Besides your (Android) phone, what USB device have you successfully connected to your car USB? Have you been able to connect another non-Android player? What about a large thumbdrive with all you tracks? It is very possible that your car only support Android devices (or Apple CarPlay) and, in...

Digital to analog music transfer through USB………. Are you sure? AFAIK the R2 or R3 don’t transfer analog music through USB.

What does your car “expect” to see on the USB port? A USB mass storage? A digital source?

I’ll express my opinion…. Now, I know you. For once, just do what you say you’re doing: don’t reply!

Just re-read this comment from Hiby about the M300 src (Android 13): https://www.head-fi.org/threads/hiby-digital-m300-android-digital-audio-player-the-gen-z-music-player-discussion-thread.970428/page-2#post-17816663 They mention a bug limiting the bandwidth to 24kHz unless touch panel feedback...

There may have been some problems with src implementation on some Android phones. See Hiby’s comments about the M300 here: https://www.head-fi.org/threads/hiby-digital-m300-android-digital-audio-player-the-gen-z-music-player-discussion-thread.970428/page-2#post-17816663 Note that the M300 is...

Head-Fi has a mechanism for the granting of medals... Could something similar be used for users to report a potential troll or sealion? No ban or posting restriction, but something like a low-bar: “you’ve been tagged as potential troll or sealion… the community is watching you…” I think that...

I was mostly interested into the earpads as a possible inexpensive aftermarket replacement. The headband and earpads on my 5909 are still in great condition, so I haven't had to replace anything.

When you say the Shanling H2 ran fine, did you confirm that every single track on your SD was playing fine? It could be that the H2 saw the exact same error, but choose to ignore it instead of trying to fix it and/or aborting the scan—which would be a worse error handling IMO…

I have not disassemble the headband—no need so far—so can’t help. But I got a set of replacement headband and earpads from AliExpress that look to be from the same vendor: same exact pictures. They are utter garbage. Quality is absolutely terrible, the stitches are black instead of red and are...

In addition to perfect level matching, you would need to find somebody to randomly swap the phones for you and restart the track you left. Otherwise, it is a sighted test, and I’m sure you’ll “hear” differences: nothing wrong with that, it’s just how our brain is wired… So, although there...

Really? Go for it, explain your process and the results. :ksc75smile: Do you still have the FreeDSP cable? Same night and day difference? Can you also do a blind test with that cable? I suspect it’s an app self-imposed limit, not a HW constraint…

I don’t have Dusk, but have a few Moondrop FreeDSP cables—allegedly the same cable. Subjectively, I have not noticed any difference between my iPhone (lightning + adapter) and Android. The FreeDSP shows up as a UAC-2 compliant audio device, supported by both iOS and Android. The DSP settings...
