In 2003 I bought ProMedia GMX D-5.1 and I loved them! They were incredibly stylish and they impressed the chicks! Although I didn't like the saucer design it did have a audio optic input. in 2005 I I had to deploy to Iraq for 7 months and my I let my roommate borrow them. By borrow I mean he took them and never gave them back. When I left the military I bought a ProMedia Ultra 5.1 system but it doesn't have any optical inputs also the sats aren't nearly as stylish.
Back then this forum had alot of mouth breathers insisting their ProMedia made an "RIDICULOUS BUZZING NOISE!... UNACCEPTABLE!" They would then make personal attacks on the forum moderator, calling her bias and accusing her of covering everything up from deleted post and the buzzing noise to the JFK assassination and her personal responsiblity in the creation of Croc shoes. I do have to say she is alot prettier than I assumed.
