Hi, finally got my lotoo PAW S1 today. First impression, is sounds great!

Got a query though, do I need UAPP to take advantage of HiRes and MQA in Tidal when using my android phone? What about on the computer?
Thanks!

For PC, Audirvana (expensive) can play MQA or you can download the Tidal own software itself. For hi-res audio including DSD, you can use Foobar2000 (free) but you have to install components to play DSD (free). I'm using Tunebrowser (free+paid which can play DSD without any add-on with top-notch interface) and foobar2000. If you want to bypass Windows Volume Mixer so the software can communicate directly to the DAC, you have to install ASIO or WASAPI to get the bit-perfect.

What do you guys think about OFS?
Does it mean Tidal app is doing unfold or Tidal app playing MQA but S1 cannot unfold?

Have googled a bit regarding MQA and IOS.
This article is an interesting entry point

Looking at the displayed bit rate of S1 when playing Tidal it seems to me that Tidal app is doing the so called 1st unfold and forwarding the result to S1
My assumption: S1 isn't doing 2nd unfold...
Anyone in this forum knowing a Lotoo contact which can clarify this?

Any one compare s1 to the new Hidizs s9?

https://twister6.com/2020/10/12/in-a-snapshot-hidizs-s9-mini-usb-dac-amp/

Interesting device especially for that low price!
No mqa support on S9
Better PCM decoding specs on S9 up to 768 khz vs only 384khz
Different tonalities (see Twister review)
If you don't need MQA and are on tight budget seems to be a no-brainer almost

The hidizs s9 have a newer AK4493EQ chip which is used in high end devices
Than the lotoo s1 with lower end dac chip AK4377.
Still the S9 is cheaper how is that?

I wrote some nice email to the above mentioned email address and got this: "Mail delivery failed: returning message to sender".
Is that some politically motivated functional restriction so I cannot send emails to Chinese receivers?
Anyone encountered something like this before?
How to contact Lotoo service?

I am just trying to help, right?

sure, not your fault, am just wondering very much how to deal with these market leading Chinese companies when such simple things are turning out to be such difficult

S1 has significantly greater feature set and build quality than the S9. The DAC chip is only a part of the equation, and a lower end DAC chip can give superior sound if the overall implementation is better. I have both and it is no surprise to me the S1 would be more expensive than the S9.

How does the sound compare? with EQ disabled on S1 ofc

Adding a picture of UAPP and PAW S1. UAPP reports USB DAC @ 44.1kHZ / PAW S1 MQA. X4

I get exactly the same thing as you on this track. I trust the display on the S1. If for some reason UAPP was not transferring the MQA bit stream, why would the S1 display MQA data that matches what the UAPP is reporting for the file?

I will have to play with both again tomorrow. Last I remember the mids on the S1 were much more full than the S9, giving the S1 a warmer (and to me more pleasing) sound compared to a leaner sound on the S9... but that is just from memory...
