How long you already worked on LTE buzzing problem? If you searched already long time for a solution, maybe it is not feasible in this small size? Perhaps just state a warning about it, that customers know? I think a lot of people are still waiting for 9038D and are eager to try itI want to ask you guys regarding 9038D, the single-ended 3.5mm jack version of 9038S. That model is ready to be released for a few months already, however, I still can't improve LTE immunity of that DAC mostly because of I/V stage and unbalanced topology. At the same time, I've got an impressive distortions figure with 9038D. For example, my AP SYS-2522 reads THD+N 0.000012..0.000014%(SINAD 117..118db) i.e. 1.4PPM maximum at no load, and 1.7PPM 32ohm loaded at 260mW. So, today I need to decide, should I release that DAC as is or I have to keep improving LTE buzzing immunity up to the end of time this universe? Please let me know your opinion about that.

LTE aka 4G/5G(3G much "softer") mobile internet uses a very wide frequency band and quite high power for RX/TX.
What does mean? In case if you gonna use 9038D with high-sensitive IEMs(>105..110db/mW why such stuff needs any HPA at all??) and play Tidal online via mobile interface(especially if you place 9038D at the backside of your phone!) you may notice some "static" buzzing. The internet via WiFi or LTE but with normal headphones(dynamic or planars, open-back or closed whatever, IEMs 90..100db/mW) no problem at all.

I agree completelyHow long you already worked on LTE buzzing problem? If you searched already long time for a solution, maybe it is not feasible in this small size?

It's a no-brainer then. Release it! E1DA 9038D (v1)EMI on the 9038D is still greatly improved compared to the 9038S G1 and G2, just not quite on the level of the G3.

I just want to make sure the 9038D doesn't have a problem with the IMR R2 Aten regarding buzz. it is right?I want to ask you guys regarding 9038D, the single-ended 3.5mm jack version of 9038S.

I am really looking forward to hearing the difference. Although truth be told I am shocked how awesome the G3 is. I am using it as my main DAC just now in front of my SP200. I sold my iFi Zen Dac and Topping D50S as frankly I do not need them and the G3 is so compact I have velcro'd it and the SP200 to the bottom of my desk to save space.oliveoilthansnakeoil
