Cycle through the menu to check if your gain setting on the W2 is set to High. The S1 also has a similar setting where you can set your gain to Low or High
Checked that.

It's a bit strange really. The W2 sounds better but my unit definitely doesn’t have more driving power than the Lotoo S1. Just been using my IMR Elysium with the 4.4mm cable on both units. The W2 is sitting at 50 to 55/100, the S1 is at 45/100 and is still giving more more volume.
Am I missing something here?

I would guess the volume numbers can't really be usefully compared. They're pretty arbitrary according to the engineering of the device. Go by sound, not numbers.

Surely not a faulty unit

I would second this. What I have found is similar to @McCol, I need a slightly higher volume in W2 to get the actual hearing volume matched between S1 and W2. However, W2 seems to have a wider range of effective volume. On W2 I can push it all the way up to 80+ and get no distortion volume (when used with laptops). On S1 the loud volumes are basically quite distorted.

It's funny you say that as I was having the same thought in the last 5-10 minutes.

Thats what I was finding in the last 15 minutes or so, the S1 starts to sound messy and distorted at a certain level.

Tried playing csgo with the previous firmware update, but issue still persisted. Now back on the latest firmware. Btw, it only happens when I play CSGO. No issues when I play music, or watch videos for hours. Tried it both SE and balanced output, same sound clipping issue. Probably an issue with the way the w2 dac/amp audio drivers interact with the game. Did not have any sound issues when I was using the Fiio Q5s previously. Anyone knows the way to reach out/feedback this issue to them? Honestly, such a weird issue. Hopefully a miracle happens and they can address/solve this issue. Thanks!

I have a theory: The S1 quotes (at 32 Ohms), 70mW for single ended and 120mW for balanced, but per channel (implies 140mW single ended, 240mW both channels). Is it possible the W2 spec of 125mW single ended, 230mW balanced actually refers to the total for both channels?

This might explain why some users are finding S1 louder at same volume level.

Unlikely. As per the graph measurement of THD+N ratio vs Measured Level:

Lotoo PAW S1 clips at 96mW at 33 Ohm load, balanced

L&P W2 clips at 235mW at 32 Ohms, balanced (maintains 235mW at 68 Ohms as well)
