I meant the play/pause, next, previous buttons on the side. With dedicated, I mean they have one function.
Anyway, I've now finally ordered a PHA-3ac. It's not portable (hence the ac designation), but I think I can live with that.
I could have bought an new PHA-1a, but a second hand PHA-3ac was only €150,- more expensive. A second hand PHA-2/1a from outside europe (import duties, I live in the Netherlands) would drive up the price towards a PHA-3ac also, so...
I'll use my macbook as a source, with the Sony 'Hi-Res Audio Player'. It would be cool if Sony had made a digital only version of their walkman for the PHA-3.
Now I'll only hope it gives an audible improvement lol
