The point of this exersise was not to praise various software upscalers, but to investigate what effect, improvements (if any) they produce when connected to a Chord Mojo.
After all, Mojo also upscales, so how could a humble $10 Android software improve the sound?
To me it certainly does, specially at 16X (found a way to keep it stable) - this means upscalling a mere 44.1kHz all the way to 705.6kHz.
I was wondering if it can be replicated by others, and could they notice what I get.
At least with HQPlayer you could replicate some of my findings. BTW , to my ears, poly-sinc-mqa-mp with no dither or LSN15 , does the trick.
Upscaling to DSD slightly improves the sound but requires more CPU.
Neutron does not use that much extra battery processing to 16X. Last night I listened to about 3 hours, my battery was down 15% as a result - perhaps 5% extra.
The more I try to find a way to convince myself, that it isn't so - the more I hear that it is so, while the book says it shouldn't!
If nothing else, at least I found a way to improve the sound of the mighty Mojo, for free.
Regarding the very short eval period on Neutron before nagging starts, I recommend leaving a feedback for them, perhaps they listen.
25 mins is a JOKE - a week is reasonable.
DSD input to Chord DACs is decimated to PCM and then reconstructed with WTA filter anyways. Using PCM as inputs at 16X base will bypass the WTA filter completely. If hearing DSD upscaled sounds better than PCM upscaled through Mojo, it just proves that WTA filter is better than HQPlayer's filters (which would benefit non-Chord DACs than Chord DACs in this case)
