Query: OK but not great

I've had my unit about six months. The cost is low, and the anti-skip works good. But my biggest complaint is with the volume. Full volume on this unit might be 3/4 volume on other units. I always have mine on full volume, and it's not what I'd consider loud. Lately, mine is having problems playing MP-3's. I'm not sure if the problem is with my MP-3's or this unit, but I'm going to buy a new (different) unit.
