You've already made your purchase so my advice is now moot.
I was going to recommend, you get an external DAC to bypass the computers, and them get an amplifier and hook up some proper stereo speakers, that is the best sound option. Although it would have been more expensive. Also you'd probably want lossless music too.
Or set up a nice headphone rig, with a DAC/headphone amp.
And to the people who recommended BOSE, the quality of BOSE speakers is about half what they cost. BOSE spend millions on a slick advertising/marketing to convince people their great products, when really they're an average product in a shin case.
They should change 'Better Sound Through Research', with 'Brainwashing through marketing'
I don't hate BOSE, I just hate that they advertise as themselves as a premium product when their not, yet they still charge a premium price. If they were actually premium, I'd like them. Or if they had prices that reflected their quality I'd like them.
