I'm thinking of moving away from the PSP because the loading times are starting to drive me nuts. First of all, can any one comment on the sound quality of different handhelds? I've heard stuff like the Dingoo has a noisy headphone out, PSP is cleanest, etc. It would be really cool if someone took the time to do a group of comparison recordings. A more definitive answer would be great.
Secondly, are there large differences in processing power between handhelds? A few of my filter and OSC heavy tunes are starting to freeze up and even do some minor distortion glitches. I guess using a desktop version would clear all this up but I want to stick with handheld (or pi) if possible. Thanks!
