After some testing with amp 13 and stock amp with my u12t. I feel that stock amp sounds more real, natural. Sometimes I feel like "living" in the records. So is amp13 needs burn-in to be better ?

Thanks, guys. I'll stick with the lastest fw. Is it ok to keeps the dx320 always charging. I plan to burn in while charging for a couple of days.

Hi, I want to ask which firmware version sounds best, I heard that sound varies based on fw ? Or should I just use the latest one? And is it ok to always charge the dx320 because I mostly use it at home. Thanks

After several years of service, my r2r000 black's screen is broken. It shows nothing now. Part of screen was dying until completely black. Can I buy and replace the screen myself or send it back to hifiman ? :(

Just bought a dx320 but I have a problem: all the red color on screen are turned into yellow. Anyone had this problem? I turned off night light

Btw sound wise, how is r2rk black compare to n6ii on r01? Thanks

I got an offer of black one about 800$, that battery hifi is about 5h, do you guys thing it's worth it ?

Never mind, restart the player, and the problem is gone, weird. Thank you for your wonderful firmware (again :D) IMO, the v2 seems to have a slightly cleaner mid and better image than v1

After the upgrade the sound only coming from the left ear. Did I do something wrong :(

Just tried the Midnight Plus, wow wow wow. The dark and smeared mid of the old Z (with my K10) is gone. The mid became so lush, detail, and emotional. Unbelievable work, @MrWalkman !!! I encourage whoever prefers the Fev2 over project Z have a second listen to the new Midnight Plus. It's a game...

Just try the project Z today, Imo the Plus mode makes the mid more laid back, darker and it's not a good match with my K10. The classic mode seems to have a better balance between sweetness and musicality. But I feel the Z's classic mode somewhat sounds softer, less sparkle, and narrower than...

With FEv2 The sound became much more forgiving with improved clarity, image stretches farther, and better bass control. Nice work @MrWalkman. A small comment, you should set the V2 as Hold button down, I find turning on and off the Hold button whenever I turn on the DAP a bit inconvenient.

Loving the FE fw so much, can't imagine what FE+ will bring to the table. Patience, patience ...

Jump to the wagon a bit late but loving the sound so far. Execellent works, @MrWalkman. In wm1a and fe, is high gain badly affect the sound?

IMO, the dx220 on 1.7 firmware and android sounds better than Mango OS the first time. Both UAPP and Neutron show a noticeable improvement upon timbre and sound stage. The Mango became a little bit warmish after this update. Some of my impression of dx220 (on amp9 and new firmware) vs Hugo 2...

Hi, sound wise, what do you think between R8 and Dx220?

Will the dx220 get any firmware update in the feature? It's been a long time since the last fw upgrade.

It continiously cracking on my mac to the point of unlistenable. I tried with the windows bootcamp but same issue.

Hi, is anyone experiencing cracking and popping noise on MAC os when using the DX220 in DAC mode? I tried audinirvana, roon, and normal youtube. All are having problems.

IMO, the sound became louder a bit. And Treble became more...say revealing ?

Are you using the free version or paid one ?

After the restoration of Neutron, I tried the pcm to dsd64 converter and the sound changed nicely. Curious if I can upsample to dsd128.I ticked the box, the sample did show dsd128 but no sound out. I noticed another bug with Neutron, though. If I play dsd native then when switch to play pcm...

Nicely done, thanks both you and @jamato8

Sorry if any asked but is there anyway to restore the app I bought on play store like Neutron, poweramp without using the play store mod? (I feel it affected the sound a bit on the bad sdee.)

On the new firmware, the battery is having problem. Previously, I can connect to my PC and charge to full at the same time. Now the batter meter continuously drops when in DAC mode. Sad
