I'd get some small ones...Ipod crap type,pc monitor crap type.. like it or not thats the big thing these days as I see it. With 2 teenagers and its a constant amount of kids coming thru the house.
You ever heard a song thru a cell phone!??? the kids live for this horrific type audio crap!! its painful.
IMO, the PC speakers are the huge "average consumer" playback system, and at least those are starting to improve..thats refreshing.
Ipods, Earpods all that type are much better than the cell phones.
playback check on a "average joes" system. Would be Ipod and PC speakers.
Assuming your going for the Younger music buying market.
If your going for Audiophile bliss.....thats another thing all together.
Now your talking B&W and SubWoofers and the good stuff...
<disclaimer> I'm just bullshitting as I drank too much coffee tonight..er..this morning?
