The z906's are on amazon right now for 250 dollars. I am looking for a 5.1 system for my computer, and am really tempted on getting them. The amp on my klipsch 5.1 promedia ultra is burning out, the connector for the front left/right channel has to be in a certain position to get audio coming to both speakers, otherwise it only does the left one.
Either way, that's a hell of a deal on the z906's. I am just debating on spending 250 for "decent quality" or spending 550 for a receiver and speakers for "amazing klipsch quality". It's a tough decision lol.
