Of course, we can't let a discussion of the Sangean HDR-1 end without listing our major gripe--that the whole HD Radio format doesn't (for most people) deliver a particularly major improvement over the analog radio experience. To our ears, the HD Radio stations weren't delivering a dramatic improvement over their analog counterparts. And while we welcomed the presence of digital-only HD2 stations on the dial, many of them seemed to be noticeably compressed--more MP3 than CD. Moreover, the data streams seemed limited to artist, song, and show title information. That's nice, but nothing that can't be done with RDS information on analog stations, and some of the HD stations seem to lack the informational displays altogether. While the digital stations certainly offer static-free reception, that's only if they're within range; a distant HD station will drop in and out if it's too far away. Even more disturbing is that some nearby HD stations seem to blink out randomly--the cell-phone-like signal meter drops a full six bars to zero and then shoots back up again a few seconds later, even when the radio is completely stationary. To reiterate, none of these problems are the fault of Sangean HDR-1. The same issues exist on the Polk I-Sonic and Cambridge 820HD, and will continue to exist for any and all HD Radio receivers until the stations decide to offer more bandwidth and better data support.
