Clark, you asked about some of the specific artifacts HD radio produces and how it falls short.
From my listening with a Sony XDR-F1HD forced to analog only (no blend) vs HD1:
1. HD1 was unable to accurately reproduce massed strings on MPR 99.5 KSJN classical concerts.
2. On MPR A Prairie Home Companion I was unable to tell the difference between a new Martin guitar and a 50 y.o. Martin guitar both played by the company’s president. Both guitars sounded the same. On the analog main carrier the difference was clearly audible and I had a preference for the sound of the older guitar.
3. On HD1 I was unable to hear the hall sound on familiar classical recordings where it was clearly audible on the analog main carrier.
I sold the Sony XDR-F1HD and never looked back. HD radio is not a Hi-Fi medium.
HD radio is also the Camel’s nose under the tent in that Ibiquity has proposed an all-digital future with no analog main carrier - effectively obsoleting all of our analog tuners and removing the only hi-fi radio alternative we have.
Tom
