Yeah, it sounds like something is wrong with it. Hopefully others with the R4 can weigh in.

Are you charging while playing? That may make it hot. Class A amps run warm anyway and it’s best to not charge while listening for better battery health.

I find the Hifiman HE400SE, as well as the Ananda Nano, are driven nicely by all my DAPs, including the anemic Sony A306 (uncapped version) which surprised me. I've been eyeing the Meze 99 Classic. They are currently $250 on Amazon. The Neo version is $200. The 99's are supposedly very easy...

I bought one of these via ebay from a Japanese seller for $242 plus sales tax. It is listed as pre-owned, but it looks like it may have been an open box return as it looks new in the original box. It was shipped Fed-ex and got here (western US) in 4 days from when the seller eventually shipped...

Cayin N3 Ultra - $529. Technically runs android but is closed off and can’t install apps. It’s a pure music player with tubes.

I'm not sure what the N3Pro got for battery life, but I'm getting at least 10 hours. It's a lot better than my RS6 and seems comparable to my RS2. It gets warm (I always have one of the tube modes on), but not hot. Definitely cooler than the RS6 and N7. I haven't heard any noise when...

So, A306 or used ZX507? I want to experience the Sony magic on the cheap and love the engineering that goes into their players. A used ZX507 and an A306 are in similar price ranges. I love the small size of the A306 with the longer battery life, newer Android and (I think) faster SOC. On the...

Mine also showed 1.3. Other than the new V2 filters (which I still can't hear the differences!), it all seems to work well for me. I'm not sure what the track order issue is as I usually shuffle, or I pick an Artist->Album, and listen to it in order. Both work the same

V1.3 FW is now available for the RS2 and it finally includes the Darwin V2 filters. I’m not sure I’m allowed to post a link but you can find it on HiBy’s website.

I believe it's a fixed delay. If your player can delay the video for a number of different static values, you should be able to find something that works.

I can't answer your question on if the SOC can handle the processing in your case, but it does have enough power to handle the HiBy plug-ins, like convolution, which is fairly processing intensive. The convolution plug-in may be able to use your profile. You should know that there is latency...

How do you like the Shanling compared to the Cayin?

I'm loving my N3Ultra as well, although I still pull out my N7 daily. @ToneDeafMonk, is your R4 a review unit or is it for sale someplace? I think that is quite a disruptive DAP and is a hell of a deal at $249.

From my understanding, no on N3Pro, yes on N3Ultra.

I can definitely recommend this dap. I love this thing and have had zero issues. I don’t recall reading of widespread issues for the N7. The price is less than it was at release. The other dap I’d possibly consider in a similar price range is the R8ii but it’s a little bigger and heavier. Both...
