LG V30

Yes...there's one difference from a regular DAP...even though the chip can decode it, the V30 is not going to play the DSD file natively and rather use the DOP method...I forgot about that. That's a conversion so it wont be as pure as native...

As for power, I am thinking of picking up either the Sennheiser 800 (good discounts) or 800s @ 300 ohms. Unlike nearly every other smartphone, the V30 has enough amp power to do justice to these hi-end cans? Or I may go for broke for the new Focal Clears...which are only 55ohm.

Not sure how much damage (if any) is being done by the DoP treatment. The link from @artpiggo suggests everything should be perfect, but there's a slight bias with that comment coming from the folks that invented DoP :wink:

I have the HD800S and the V30 drives them easily, so you should be fine with any of your options above :)

I'm using BeyerDynamic DT880 250ohms and have no issues...plenty of power.

Have you tried the regular HD800 as well? Are the "treble-tamed" S model worth the premium? I would think it would only be treble-enhanced for 'lesser' recordings...i would be almost all DSD. You can find the original for $600 or so now so quite a difference.

Honestly, if you're willing to put in the super-dupont mod yourself, buy the original HD800 and you'll save yourself a lot of money. The only other difference is a slight lift in the bass in the HD800S through some added 2nd harmonic distortion. I'm not sure exactly how Sennheiser did that - seems to be some modification to the driver. In any case, it's less significant an effect than the damping of the 6kHz peak.

Further testing and I can say that all 16 bit media is played through the android mixer and resampled to 48khz regardless of sample rate or app used for playback.
24 bit playback operates in direct mode for those apps that take advantage (LG Music Player, BubbleUPNP)
Tried 16/88 and 16/96, both output as android mixer 16/48

Thanks for that feedback! I do find it an odd oversight to need to be resampling the most commonly-used redbook FLAC format (16/44).

While I understand it downsamples, Neutron bypasses the android mix. At least on my V30 it seems to operate independently. Of course, If it downsamples, that doesn't help.

Could you please include an adb debug verifying this? I have tested other apps and posted my results, no one has posted a neutron debug yet that I know of. I would like to see verification of direct output. I have the adb data to back up all my statements.

I'm afraid you can't always believe what these apps tell you on the "Now Playing" screen.
Neutron up-samples redbook FLAC, just like every other app I've so far tested:

This is after even you set up as per latest version neutron tells in link below, right?

EDITED: After reading comments in the threads, it seems LG V30 still not compatible with neutron HiRes setting fully.

Whoops! Apologies to Neutron, @jtfrazier and thanks to @artpiggo !

Still, it's interesting. If one could somehow fake a 24/44 stream by adding to the bit depth of a redbook FLAC file, it seems one could avoid up-sampling.

@csglinux why the last report one 24/96 out sample rate at 44.1? Is it weird?
 
Nov 7, 2017 at 10:49 PM Post #1,155 of 6,140
I don't know. Hi-res PCM and DSD are reported as going through the ESS DAC, but not at the correct sample rate/bit depth.

Could you try enable Follow the frequency in Audio Hardware in Neutron setting?

However, I believe it is a glitch for V30 because it is a new model so the neutron still need to adjust and research more.

You can send email on these results to neutronmp@gmail.com for Dmitry to investigate on this.
