I have Tapco S8 speakers and they are great. They don't have volume control though, so I am thinking about buying some amplifier, because controlling the volume from Windows sucks big time! Also I cannot use any shielded cables, which doesn't really improve the sound (the hell when I receive a SMS... lol). I have Auzentech X-Fi Forte card, which has optical and regular analog output. Is there any stereo amplifier out there which would support optical input and some ballanced output? Aside from regular RCA connectors the speakers support TRS and XLR ones. Does anyone have any knowledge in this field please?
