I've still got my Logitech Z-3e speakers. I thought they were done for but the problem was my old amp. I now have the Logitechs connected to the new amp through its headphone socket, with my floorstanding speakers for music hooked up to the speaker outputs and the S/PDIF from the PC straight into a Yamaha amp. This allows me to use both sets of speakers independently.
I use the Logitechs when gaming and they still sound great, especially when using the DAC in the Yamaha. I only ever have 2.1 sound, but that's all I want.
