I have a mid 2012 non retina MacBook Pro and I wanna get either the Logitech Z-623 or the Z-625 computer speakers. My issue is I want the Z-625 because they can use optical connections. I use a tv as my second monitor and it has an optical port while my MacBook Pro does not but the MacBook Pro can connect using 3.5 mm. So I don’t know if I should get the 623 which uses 3.5mm and connect it straight to my lab top or if I should use the 625 with optical and connect it to the tv. I know the direct connection is better but is it justified by the improvement Optical brings. Thanks in advance.
