Thank you Frank.
The Hi-Res file (Diana Krall Love Scenes) I purchased from Acoustic Sounds worked fine, though there is a moderately loud pop before the first song starts. The only thing I didn’t like was the price, $24.95 for the download when the SACD sells on eBay for $15.
I will check out the threads re Hi-Res music that won’t play on the DMP. Do you know if that’s supposed to be fixed when the new OS is released. That sounds like kind of a big deal.
