Never will a buy another Diamond product again. This is the last one that gave up on me. I've had 3 Diamond modems, the Rio mp3 player, and the MX400 sound card. None of them lasted over a year. I built my computer in February of 2000, and I decided to use this sound card. It had pretty good sound, but I was always adjusting the volume level because it was different with each device I used, and this came to be really annoying. Last week I put in a new hard drive, and after that, the MX400 no longer worked. Windows didn't recognize it at all even when i tried disconnecting the new hard drive. I'll tired of Diamond products, and i'll never buy anything from them again!Can you imagine that I used to think Diamond was the best.
