The problem is mutually exclusive mandates, followed by the unquantifiable term 'HiFi'. If you're happy with mp3's & 10 watts, the amp you bought should be just fine. I searched ebay for 'passive hdmi switch' but everything that comes up is actually active (powered). Still, probably minimal power hit compared to a full blown media center receiver. 5 port switch for well south of $20 US.
The quick & dirty would be a low end automotive receiver/CD/DVD that will run off 12V. find one with external video/audio inputs, add one of the hdmi switches and an hdmi>VGA+audio converter, and listen.
If you actually care (a little; that's all you're going to get :-) ) about sound quality & want low power, plan on really big speakers. It takes a lot of energy to reproduce bass, and the smaller the woofer, the less efficient it is, in coupling the mechanical motion of the cone to the air. Can be fixed with a horn, but there goes size again...And money.
