I am looking for a good portable device to hold my vast collection. I was thinking of a mindisc player but thet tend to jump when i am jogging then thought about an I-River or sony hd. Sound quality is very important to me ,I have listened to my nieces's i-pod and I-river and didn't think they sounded as good as my old basic minidisc player and certainly not as loud or bassy. The other problem I have is a lot of my albums have continuous music Eg.dark side of the moon so don't want gaps between the songs which I know the minidiscs do fine but am I right in saying the others don't? any help greatly appreciated.
