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?
