Mine's not overly impressive, and I didn't spend much on it. Just an old Pioneer stereo system, 4 speakers hooked to it, and an Aletc Lansing 2.1 system. Sounds pretty good really. I don't use it much though because I like it loud, and loud doesn't work so well with other disapproving family members, lol.
This was my setup before I got the desk, to show you the other speakers behind the monitors better. I switched around the speakers from the floor to the desk and vice versa because the wire lengths of the blue/silver ones were too short to be on the ground...
Pioneer stereo: given to me
Pioneer stereo speakers: came with the stereo
Panasonic stereo speakers: also given to me
Alec Lansing 2.1: replaced my 2.0 Altec Lansings that finally gave up, $30ish
The stereo actually really only works with Auxiliary on anyway. The CD changer died before I got it, I further broke it so it wouldn't randomly open the tray all the time... The tape player went next, and the radio never really works too well in my room on any device... I got an Aiwa for free as well with the speakers, but it doesn't sound as good. The CD changer is dead on that one as well, lol. Since it's hooked to my computer, I play all music through my comp anyway, so no biggie for decent freebies.
