Opus...found an Advent 300...9 hours of driving. 300 was totally recapped and not burned in... highs were very harsh ...I left on for a day...now highs are softened and sounds just fine. With only 15 watts it likes larger more efficient speakers. Although you notice the limitations of the 300 quite early, now looking for a Advent 350 or 300 for my Daughter. Keep checking those curbside boxes in Medford.
Ebay could be another possibility also.
Hope I was helpful.
Enjoy,
Opus
