Newcastle Upon Tyne GB Don't tolerate bad service
good price
setting up the 5.1 to run with a fiber optic home surround system was a bit of a faff.

Southampton/ Hedge End GB Experienced, Fussy, Educated
Much better sound quality than any onboard sound card and great price
front panel can be an issue if headphones be used. nothing serious but can be annoying. also, impossible to turn the sound effects off but only choice is to choose "room" for natural sound.
