OK I was intrigued with the Music Hall a15.2 but a couple of dealers complained of some returns maybe the result of poor parts/supplies they were getting....One dealer told me I need something powerful like the c375, and another dealer said the X12 needs very little amp power. Go figure!
Just found a great deal on the NAD c356 from Spearit Sound in Northampton, MA...refurb with free shipping and under $700! Highly recommended as they have other refurb deals too...don't be shy about asking for additional discount on the listed prices. Thanks everyone.
