Ah! the Marantz has problems. Sell it on Ebay, get a Teac and you'll be able to crank up the tunes to your heart's content without sacrificing sound quality.

OTOH you might have a tin ear like VeeP in which case the Bose would be fine but waaaaaaaaay overpriced. Got to the Target and get a Tivoli clone for $60 and spend the savings on sex, drugs, and rock and roll.
