Being my first post as a member i'd like to say hi to everyone. Anyway down to business. I have a new MBP and would like to know 1) If it is worth upgrading my current analogue cable running to my sony CMT-CP500MD stereo to the digital option, is the sound quality noticeably better? 2) there is quite a large distance between my stereo and where my laptop general is, about 7m, where can i find a cable that has the proper connections and is about this long? The optical connection in my stereo is a toslink. On ebay there is a 10m option but only with duel toslink ends. thanks guys
