This is especially true of HD car radios. There are also several sites on the Internet where you cannot only buy HD technology radios, you can compare prices for several different sources. Among these are NexTag,  and Buy.com.

As of this writing, there are seven manufacturers offering compact, portable, tabletop radios with HD technology that offer amazingly clear, room-filling sound. These manufacturers are Radiosophy, RadioShack, Sangeon, Polk Audio, Boston Acoustics, Sony and Cambridge Soundworks. More manufacturers are expected to announce portable, tabletop radios soon.

At least seven manufacturers offer HD car radios, including JVC, Panasonic, Kenwood,Sanyo, Sony, Alpine and Eclipse. Again, more manufacturers, including Sony, are expected to soon announce HD Technology car radios.

Finally, three companies have component-type HD technology receivers available. They are Yamaha, Audio Design Associates (ADA), and Day Seguerra. All three of these HD technology-compatible receivers are designed to be used in conjunction with home theater systems. You may find one of the HD Technology receivers at your local home theater retailer or high-end sound components store.

Sangean HDR-1 Tabletop Radio

The Sangean HDR-1 tabletop radio gives you everything you’d expect in an HD radio – AM sound as clear as today’s FM and FM as clear and clean as if you were listening to a CD. Thanks to my special price, it’s just about the most affordable, top-quality HD tabletop radio available and represents a great price value.

As you would expect, the Sangean HDR-1 tabletop radio lets you hear all those “invisible” HD2 channels between the regular frequencies – where broadcasters have put different and, in some cases, very non-conventional programming.

Plus, the Sangean HDR-1 tabletop radio displays text information, such as station IDs, artist names, and song titles on its large, easy-to-read LCD screen.

In addition, the Sangean HDR-1. has two 2-1/2″ speakers set in the acoustically tuned cabinet that deliver rich, detailed highs and mids, with nice, round bass. You’ll also like the sort of hip, retro look of its nicely finished wood cabinet.Letting the HDR-1 wake you up almost makes the morning fun with its built-in digital clock that displays both time and date, and includes dual alarms with snooze, as well as a sleep timer. Adjust the sound with the bass and treble control, or just use one of the EQ presets. And you can operate the radio from across the room with its provided remote.

Sangean’s suggested retail price of this tabletop radio is $249.95.
