  Here's what I have found comparing My LG G4 that has a Snapdragon 808 with DP-X1. While playing Depeche Mode' Policy of Truth in 5.6 MHz DSD using Onkyo HF player, all six cores were active and the CPU use was around 18%. Playing the same file on DP-X1, only core 1 and 4 were active in both SE and balanced mode, with CPU use around 30%. It looks like something is doing the work of decoding that 1.2GB song on the DAP since 2 cores don't bother waking up
 
I have used CPU-Z to monitor CPU use.

That seems conflicting, forgive if I'm missing the obvious. So if all four cores on the LG are working, but the CPU use was 18%, but the CPU was used more on the DP-X1 (30%), even if it is only two cores, doesn't that support at least some of the processing for the HF Player happening on the CPU?
 
Edit: unless the relative strength difference between the CPUs was such that 30% on the 801 is essentially equivalent to 18% 0n the 808.

Six cores in the phone were working while there were only two in the DAP were processing . Snapdragon 808 cores are quite faster than 801, too

Can you compare with the stock Onkyo player playing a file as compared with the HF player. Thanks. We would expect to see no difference between the players playing the same file if no extra processing was done on the CPU, which we all seem to agree seems to be the safe assumption.

On the DAP? No, as I don't run HF on that. I'm reluctant to install it as it might conflict with the default player

How about downloading the trial version of another program to compare? Actually I have the XTZ app on my system. I can disable it's DSP and install the CPU-Z on my Onkyo. Why don't I do that?

Tidal playing HD file (offline album): G4 6 cores on, CPU use  30%, DP-X1 core 1 and 4 active only, CPU use 12%.

I just compared on my DP-X1 and with the stock player and the XTZ player there appeared to be no difference as expected. At first it seemed otherwise, but I just kept testing. The CPU use of course changes constantly  but it appeared to be the same. Same number of cores in use as well, and same cores.

How do you get a static core use number? My core use % field changes constantly so I have to look for the relative use and make a judgement. Is there a setting to get an averaged use percentage?

 

[sabloke]

I'm just guestimating of course The CPU use varies on the G4 a few % under and over 30%. Easy with DAP cores 2 and 3 (or as they are numbered correctly, 1 and 2) are idle.

I just looked at Tidal with offline content and it appears to be a very similar CPU load so again this would support the theory that all music apps seem to use the CPU the same. I may download Neutron again and test, but that is a pain in the ass and I should be doing some school work.

Bought my first IEM. It is a local brand from HK and cost only $50 usd.

Nice, based on some recommendations I just ordered a LZ Z03A today myself. Apparently the Z03A sounds excellent despite the price. I'll see. I didn't want to risk much money as historically it is almost impossible to get things to fit inside my ear so we will see.

It is good to try some small brand for fun.

Don't forget to vote in the poll thread about your experience with Tidal and the DP-X1.

Thanks to those who have. I do think there was one vote registered as a DP-X1/Tidal issue when it seems like it might be something else. I'm trying to get my head around this. One person posted he only gets distortion with Tidal, but also only when he uses the balanced out. That defies what we seem to have established in that Tidal uses the exact same audio output path so if that is the case there can be no special interaction between Tidal and the balanced circuitry. That would suggest it is a hardware issue and really it should show up even without Tidal being used. I can't see how that is a Tidal/DP-X1 interaction fault. I might be missing something of course so feel free to suggest away.
