I had a look on the 'anything but iPod' forum and couldn't didn't anything regarding to low-volume... I can only surmise that you are on about the Euro-models that have a volume-cap (this also pertains to any mp3 player in Europe), on the Sony WM-Z the volume cap equates to approx. 85/90% of the standard model so the WM-F should be in the same ball-park... using my new IEM's with the WM-Z I find that maximum levels are too much for my ears, I have trimmed my listening volume level by about 25% to compensate, the Sennheiser Amperiors I owned were easily driven by the WM-Z and were more than loud enough.
so I guess if you want to bugger-up your hearing do what Achmedisdead recommends, buy a amp.
not quite right...............this is line out to aux in of a car stereo and requires car stereo at max volume.
volume cap applies only to headphone out and has no impact on line out volume...........seems like they set line out per volume cap setting.
i have no problem with this unit driving headphones, it is the line out voltage (with a LOD) that is the problem.
and there are lots of reports of low volume (for older walkman/players) on 'sony insider' and 'anything but ipod' and the only solution seems to be to futz with the service menu, hence my request.
again, the line out volume (not the headphone output) is so low that i have to run my car stereo (kenwood dnx9990hd) aux in volume very close to max, which is not necesary with an ipod LOD.
