I hope I dont jinx them, but here goes:
I have been enjoying my ProMedias for about 7 years (8 maybe? I got
them in 1998-1999*). I originally got the ProMedia V.2-400s, and
later purchased the CP-1 in 2001. They have been, by far, my most
thoroughly enjoyed purchase of electronics yet. I use them almost
everyday, and I have never been shy of cranking them up.
I am going to have to guess that you dont hear from people without
problems simply because they dont have a reason to come here seeking
help.
*I still have the original package, in the event I am incorrect and they simply did not exist in 1998.
