Here is my two cents, for what little that is worth!
A wonderful audio experience
These do not get a lot of love, i used to say yeah they look nice, but they have no power, probably not as good as the larger family members.
Well i was wrong, this thing just sings! Coupled with some high efficiency speakers, this thing made my feet tap and my head bob. I stopped looking at the unit like a piece of low end audio gear, and just listened to the music, it just pulled me in and wouldn't let go. I am not good at spewing out the verbiage that is thrown around when describing how a unit sounds, but i do know this, when i stuck this on, i was amazed. Its so unassuming, but it is delightful, small but plenty powerful, gotta love those meters bouncing to the music too. Pioneer knew how to make them. Snap one up for yourself!
