In the line out mode, the volume is very loud even if the phone volume is adjusted down to almost zero. Am I missing something?
This is how it should be, exactly at 100%, because this setting is not for headphones, but an external linear amplifier.

I lost track of S1 developments, but great to see line out in new FW. Just tried it with a Cayin C9 and WP900 - very clean and dynamic sounding. Kudos to Lotoo for keeping things fresh.

Does anyone know how much is the power output of line out mode?
Line Out setting, not intended for low ohm loads, used for headphones, increased non-linear distortion.

I am a little confused by all of the “line out” celebratory posts… Essentially, isn’t this line out basically max volume and turning all effects off? This is a feature an S1 owner could have done on their own without FW update…. The FW makes it very quick and simple, but Lotoo did not actually provide any new functionality with this FW.

Or, am I missing something?

I played 1 song enabling lineout feature vs using pre-amp (use it as normal phone out) with Cayin C9 (Preamp Mode - 100% Volume on S1; Lineout - 100% Volume on C9)

I see about 3-4 dBA headroom in lineout mode, if that helps.

Edit: Forgot to add. Audio Technica ATH-R70X (High Gain on both S1 and C9)

I only played the S2 line out about 30 min to a portable speaker with volume control but it seems far less battery drain from phone. Typically bypassing the op amp to avoid coloration is a key line out feature. Not sure the topology of this firmware and setup however. But for me when using this speaker setup it’ll be power use reasons where by comparison full volume if that was the test would cost more battery.

Using the S1 in Line out mode to my Headamp Pico driving a pair of ER2XR and the sound to my ears is far better than what the little S1 can muster out on its own. This new Lineout feature makes the S1 a very good sounding and extremely versatile device, IMO.
