Thanks, Richidoo. Both artists, Perfecto de Castro and Andrew York, are sending replacement CDs. Both are very talented musicians and I am hoping for the best. I'll let you know. P.S. My ADS l810s are doing fine. So far I cannot detect phase problems with the Polk center channel, but my ear is not as well trained as it was when I was younger and in the business. The Polk is fine for me, but if I stumble on a single l570 I might that.
