10v in s9, did you mean samsungs phone outputs 10v?9038s has quadriple more power at low impedances, at 300 ohm it's lower because of power supply voltage limit (5v from usb vs obviously 10v in S9)

Amir video mention about increase thd+n due to driver.It's a shame the performance drops so much once loaded. At 300Ω, it's already 8dB short of the unloaded THD+N and that gap widens to like 15dB at 33Ω.
Is there a good review with measurements of that one anywhere?Which is pretty much obsolete it self when compared to something like HiBy R3Pro regarding it's additional abilities. However this is DAC/Amp dongle size category.
Proper one unfortunately not yet (or at least I don't know for it) and that's DAP.Is there a good review with measurements of that one anywhere?
Only criticism I have with qudelix is the non SOTA SINAD...
I miss the hardware volume buttons of the S8 here.
Agreed, so better phrased, I miss the hardware buttons of the S8 but with smaller volume steps.I find the hardware buttons far too broad in impact so usually control volume from the player app anyway. One step up on the buttons with sensitive IEM can be the difference between enjoyably loud and deafening.
Yup. That's what an ideal dongle would have.Agreed, so better phrased, I miss the hardware buttons of the S8 but with smaller volume steps.
The sensitivity of the Aeon RT is very low (see Amir review). It is therefore quite logical that the S9 cannot drive it properly.I don't know if mine is broken but my S9 cannot drive Aeon RT closed, it has horrible bass clicking at high volume, distortion is through the roof. On 250ohm dt770 I dont get this problem. Maybe it is the headphones.
Mine also has intereference sounds when I plug it in. It is like you leave your phone next to a speaker, sometimes when you get an incoming call there is this buzzing sound. But I am not getting any call.
But I only tried unbalanced. Will order balanced cables to try.
Also on Windows it will not let you get to the distortion level, it will be fine but Aeon will not be loud enough for some songs.
Using apple USB adapter it will also not let you get to distortion level, it will just say "this accesory is beind disabled because it uses too much power"
But if you are on android or use the hidizs lightning cable it will get louder but distort in bass, at least on my Aeon. But my other headphones are okay.
But then again high sensibility 32ohm headphones dont need this power, I can just use apple dongle.
Not really enough power for DT990 600ohm.
Well, LG G7 have 2x Dual ES9218P since 2018!!player with a touchscreen with dual ESS Sabre 9218P chips, that also has SE 3.5mm and balanced 2.5mm
Yes the G7 cell phone!Well, LG G7 have 2x Dual ES9218P since 2018!!
Also the Hiby misses PEQ from all I gather so not even in the running.Proper one unfortunately not yet (or at least I don't know for it) and that's DAP.
I like the idea of heat-shrink tubing, especially as the Apple cable is so thin. That removes the main objection to the Apple adapter IMO (assuming it has enough power). Which size did you find works best?This looks like a great piece of gear. The results are impressive. However I still use my Apple $9.99 (sometimes $7.99) dongle. it has a great score for the price. I keep 2 around. I did shrink wrap them so they last and have a spare just in case I misplace one or breaks. For $9.99 or even less its a great deal. If we ever do a SINAD to $ Ratio, this would easily be number #1. Lets see 99.001/$9.99 = 9.91 S$ . Now lets do it for the HIDIZS S9 112.63/$119.99= .9386 S$. What about Topping DX3 Pro 106/$224.99= .4711 S$. So the Apple is a great deal, sure for walking and portable listening.View attachment 117426
