You can absolutely trick the 40 into high impedance mode, which I do for every headphone I own. All you need is a Y splitter cable and a high impedance set of ear pods (or any headphones that are 50 ohms or greater. Plug the ear pods into one end of the Y cable, then plug the Y cable into the phone. Next plug the headphones you want to use into the other side of the Y cable. Lastly, remove the ear pods from the Y cable. You can pick up a set of VE Monks for 10 bucks. They will kick your phone into high impedance, and you can pack them along with the small Y cable anywhere you go.
Ummm...I wouldn't exactly call this straightforward
Sure would be if LG would just offer us the gain choice like my Calyx M does...but unfortunately that great sounding, totally underrated player with a lot of great features and a
desktop version sabre DAC, will never handle ISO files or have any online capability.
Speaking of those files...and pretty much any other request for
UAPP--i have to give it to developer
Davy and his responsiveness to email suggestions--unlike a few others...cough..Neutron. Who's with me here in Kudo'ing this developer? I helped him work though for ISO support (including DST) and he just incorporated my latest request in one day--adding the only missing feature i could think of:
a sleep timer. You'll see it in the next build in the pull-out menu...
