I want to connect passive speakers to a Chinese clone of the Violectric V281, the Accurate Audio HPA-A281 (upgraded from a Lake People G109; amp is connected to an Audiolab M-DAC) which is basically identical (think Gustard H10 vs Violectric V200) and want to buy some speakers since I don't like...

Am I missing something?  Most AMP's such as the Asus Xonar Essence Muses only have 1x optical, 1x coaxial and 1x usb inputs plus analogue connections.  It seems either manufacturers expect customers to switch inputs (not hard) or only own one device with an optical input.     I'd like to see...
