I'd take this reply with a grain of salt. The P1 are 50 ohm and sensitivity of 96 dB/mW
A device with an output of 80 mW into 50 ohms will drive them to an an insanely loud 115 dB. That's permanent hearing loss levels.
I just fired up my X3 2nd Gen - which has a max output of 200 mW into 32 ohms. I then measured the output with a calibrated SPL meter using a moderately well recorded track (Dire Straits "Sultans of Swing") with the X3ii at max volume on low gain. This gave peaks at 99.3 dB and seemed to be averaging around 95dB. Engaging high gain pushed those peaks over 100 dB.
To get to my normal listening level of around 70dB required 60/120 on low gain - and sounded perfectly well driven.
Hi Brooko,
I hope all is well. I don't have any testing equipment or such. I only talk based on my opinions. When using fiio x3 with pinnacle. i always used minimum of %80 volume for some songs i wanted to go more than %100 of the volume. but with fiio x3 i had so much ground noise/hiss. So i went to ibasso dx80. Now i still use it about %70-80 of total volume but there are no hiss whatsoever.
>270 mW (32 Ω/THD+N<1%) this is x3's power output according to fiio.
