That's fine. Can't keep up with the tech updates now days.Then you'll have to wait 10 months and the arrival of V40 ; ) I bought myself a V10 late, and a V20 a month ago.

Great, thanks. Looks like UAPP improved. Last time I tested its switches were not working as expected.These two examples were 44.1 redbook
preprocessing is another thing, unrelated to SRC.Seems like the answer to disable upscale is here https://source.android.com/devices/audio/implement-pre-processing .....

BTW, I assume you are playing lossless content, right?
I've had some time to get used to the sound now and overall this is a stunning musical device. Especially considering it's not really a musical device....
The sound is absolutely grainless, punchy, detailed and smooth as silk. Still think there's a hint of sterility/coldness, but it's not as bad as I thought it was during my initial impression (I had a headache brewing that day that didn't help). It's not the best I've heard in the my life, but damn... I can probably live with this thing the rest of my life and be moderately happy.
On another note, I hooked it up to my Auralic Taurus amp and while it made a difference it wasn't as big as I expected. Both the DAC and amp inside this device are very good.
does anyone know if adjusting the balanced knobs in the high res sound settings would improve sound quality? i heard decreasing both to -3dB or -6dB would increase dynamic range
Are you talking about the Hi-fi DAC volume knobs under sound settings? These are actuated automatically everytime you change the android master volume toggle on the physical phone. It is just a way to control left and right balance independently. They in-turn all act on the AVC where the volume is lowered in the analog domain entirely in the Hi-Fi DAC. So lowering the volume will lower the noise floor by the same amount. I dont see how it can improve DNR though, because max volume was just decreased by that same amount. The great thing here is that bit depth is not touched as in digital volume attenuation. That is at least my understanding...please correct me if I am wrong.
i don't get how volume can affect bit depth. how loud does it have to be to experience 24-bit or 1 bit DSD? (by loud i mean both in dB and in the volume number on the phone)
i did notice that when i increased the AVC from -6 back to 0 the sound had a larger soundstage and better instrument separation and less distorted and my digital volume is usually always at 45-65 on the volume meter. what settings do you recommend though? (on the AVC + digital volume)The way traditional digital volume controls work (including the way the Snapdragon ASICs work) is simply truncating the bit depth. With each digit you drop you reduce the attenuation of the resulting signal by several DB. Remembering that bit depth is the way all dynamics are conveyed in PCM. With AVC in the Hi-Fi DAC bit depth is retained, and attenuation is done entirely in the analog domain (like a potentiameter does). It is done in the IC still, but on the analog signal before it exits to the headphone jack.
There are ways around stopping loss of quality with digital volume controls.....especially by padding the 16 bit word to 24 bits... or even 32 (as in modern DACs). Thus reducing the low order bits isnt actually touching the original signal. But this doesnt have the benefit of reducing noise floor as AVC does as the volume drops.
With DSD it is much trickier --- because we have to peel back the onion even further to understand better what is going on. Realizing that even PCM gets converted inside the DAC to a pseudo DSD stream. This is the way all Delta-Sigma style DACs work. So even with PCM we are listening to DSD really. with DSD natively rendered (cant access this yet on the 9218 in the V20), the pipleline is more simple. But whenever we listen to DSD today, it is converted to PCM first....treated exactly like a native PCM stream from that point -- including the seemingly redundant conversion back to DSD inside that Delta-Sigma DAC.

well...actually not always the same, that depends on the app, the system and the content.Yes the files are all originally FLAC encoded. But at this point in the decode, lossy or lossless are the same PCM 44.1 stream handed off to android since the app is doing the file level decode. And even MP3 files all decode to the original PCM rate (usually 44.1)
Lg music player sampling rate 48000 uapp 41000. I thought music player was supposed to be 41000?no. read post #1763
