is this a DX200 beta version George?

I am really sorry to both of you, I confused threads and thought this was the DX220 thread, I don't think there is one out quite yet for DX200, but I do guess that the changes that are coming to DX220, in regards to better volume integration with AMP9, will also come to DX200.

I am selling my DX200, if anyone is interested, here is the link: https://www.head-fi.org/conversatio...ass-screen-protector.2814642/#message-6893807

That is my understanding.

I wonder if there is any input lag when using this as a dac for computers? Thanks

None that I can perceive. I sometimes use it for gaming and it performs well.

Still no firmware updates for DX150/200 users with AMP9

I know. Strange that iBasso is making us wait but Fidelizer has updated ROMs based on the latest DX220 firmware:
https://www.fidelizer-audio.com/portable-products/

I installed Fidelizer 1.13 on my DX150 and can confirm AMP9 now has low and high gain settings.

Still waiting for the official update from iBasso tailored to my device but, for now, Fidelizer may be a good option for the DX200. Installation is a bit more involved compared to official updates but I found as long as Verity is properly disabled (player should auto reboot if done correctly) the process goes smoothly.

I find it quite complicated to install Fidelizer ROM. I prefer Original with Lurker mod to further extend my battery life, still works perfectly. When Amp9 was released, the fw for dx200/150 came just a bit later but when it comes to this fw with high/low gain option it has been like 2 weeks now(?) This is sad, it is like iBasso is forcing us to upgrade to the latest model.

Agreed. Not good making users of their other daps wait. I even emailed iBasso after getting AMP9 and suggested high/low settings for it should be in the next firmware. DX150 was also released after DX200 but no update for either yet. Wonder how long DX220 users will have to wait for updates once DX220 Max is released?

It does not mean it works. Just like DF filter settings from DX220 are there but they don't work on DX150.

I'm able to flash firmware pretty easily now so I tried it anyway. For now, the extra power from AMP9 will do until official firmware arrives. I'm also hoping you will do a stable Mango OS option for DX150 after iBasso does their part. Thanks in advance.

I posted my findings here on the latest Fidelizer:

I also an advocate for the high/low gain idea, I commented on the DX220 thread because it is more crowded there. I don’t think the Max version will affect as much as it don't have interchangeable amp module.

FYI, I ended up installing the Fidelizer firmware and then the latest DX220 firmware so that I could use the PMEQ that comes standard on that load. Also loaded the Lurker firmware and downloaded Neutron Player through Google Play. In both cases boosted the bass and for 90% of the music it sounded fine, but for 10% of my music with prominent bass already (EDM and other) I ended up with annoying distortion in the bass - happened through every set of headphones I own.
Coincidentally I also recently found a Lotoo Paw Gold for a great price so I bought it and in comparison with the same PMEQ settings there’s no noticeable distortion.

Although no one else seems too interested in this PMEQ discussion, I thought I would just give a short update to the issue I was having with distortion. In the end what solved my issue was increasing the 'Q' on my PMEQ settings. Using a low 'Q' of 5 or less (on a 'peaking filter') I would get noticeable distortion of the bass (I'm boosting both 50 and 65 hz by 3 or 4 dB) but with 'Q' settings of 10 or more (I'm using 15 now) the distortion disappears. I'm not quite sure why, but I guess who cares if it works. Obviously increasing the 'Q' narrows the width of the frequency boost, but I'm not sure why that reduces the distortion I'm hearing. Now sounds great with my Shure KSE1200s.
