In my neck of the woods the only black discs I can get are Memorex.  While I haven't had any prob with the several hundred I've used, I know Tyson has had terrrible luck with them.  Suppose I could probably buy em online somewhere.
So, do you guys believe the black ones sound different/better than silver ones?  I haven't had the chance to try it myself yet.
I'm using a TDK VeloCD right now, and I'm pretty happy with it.  I have a KHypermedia unit sitting in the drawer awaiting install; my brother has one and it'll read damaged discs that befuddle my TDK.  Is the Yammy better yet?
On a related note, how much difference have you noticed in discs burned at different speeds?  I burn at 8X, mostly because discs burned at higher speeds won't reliably play in my aging Phillips player.  I suppose it's audio nervosa, but I'm leery of going faster as I've heard the discs don't sound as good.  I'll probably give it a try someday, but I'll probably need to buy a new CD player first.
Since I installed a bigger HD, I mostly leave tracks on my computer now instead of needing to erase them after each disc.
