In addition to the digital version of the analog stations you already receive, many stations also offer "multicast" or HD2 channels. These secondary channels are generally digital-only stations that offer alternative programming. Yes, many of these are available online, and some HD2 channels are merely simulcasts of AM news or talk stations that you can hear elsewhere on the analog dial. But the big selling point here is that--unlike satellite radio--the HD Radio content is completely free. You just need to pay for the hardware. (For a complete list of the HD Radio stations in your area, check out the HD Radio Web site.)
The HDR-1 offers a few other nice convenience touches as well. Analog or digital stations can be stored in any one of the Sangean's 20 presets (10 FM, 10 AM). An HD Seek mode lets you roll through the available digital-only stations. And for analog stations, the HDR-1 supports RDS data, so you can see the text display (song and artist information) on stations that support it. The HDR-1 can also be set to lock into analog-only mode, which is useful for distant or weak stations that never quite properly "lock in" to digital mode.
In terms of sound quality, the Sangean HDR-1 delivered the same sort of standard performance we found from most of its competitors. Like nearly any radio or iPod speaker system of this size, there's not much in the way of stereo separation, and Sangean doesn't even offer an "expand" or "3D" mode (not that they usually work anyway). That's not to say it sounded bad, though: music had ample weight and presence, especially when compared directly with the Tivoli Audio SongBook and even the Boston Acoustics Recepter--though both of those are monaural analog models. And the ability to tweak the Sangean's bass and treble settings to our liking always helps customize a sound that's more pleasing to an individual listener.
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.
If none of that scares you off, the question becomes: is the Sangean HDR-1 worth buying? At $200, it more or less matches the price of other namebrand HD Radio tabletops, including the Boston Acoustics Recepter HD, Cambridge SoundWorks 820HD, and Sony XDR-S3HD. For us, the admittedly attractive retro styling of the Sangean is overshadowed by the control shortfalls: both the single knob nor the credit card remote are more frustrating than intuitive. By contrast, the controls (just one extra knob makes a world of difference) and the better display on the Cambridge keep that model at the top of the heap. Those who like the Sangean's wood finish may also wish to check out the Sony, which is similarly styled. In the meantime, a lot of us will continue to wait for HD Radio to simply be a standard feature that's folded into run-of-the-mill AV receivers, audio systems, and boom boxes, rather than something that requires paying a big premium--or the purchase of a whole separate product.
