The Radio 705 lacks any clock or alarm function, but it does offer a 30-minute sleep timer--just depress the power button for a few seconds, and the color will change from green to yellow. Otherwise, that's it. But we're not going to fault the Radio 705 for lacking features, since Cambridge offers a collection of beefed-up sibling products: the $179 Radio 820HD (which adds a more modern design, HD Radio, digital tuning, and stereo speakers); the $199 Cambridge SoundWorks Radio 735 (basically, the older Radio 730 with an external iPod dock); and the $249 Radio CD 745 (an update of the Radio CD 740, also with an iPod dock thrown in).
If there is one thing missing from the Radio 705, it's a rechargeable battery. Rather than have such a small radio always tied down to an electrical outlet, it would've been nice to see it be as easily transportable as the iPAL and the SongBook from Tivoli. And while the control knobs--especially the tuning dial--were a pleasure to use, the rubberized surface looks as if it could get gummed up and dirty pretty quickly, and wouldn't be easy to clean.
The Radio 705 is "just a radio," and, as such, we were a little disappointed with its tuning abilities. FM reception was very good, while AM was merely OK. True, we were testing in Manhattan, which is a veritable Bermuda Triangle for radio signals. But we auditioned the 705 next to a 10th floor window with the antenna wire tacked to a wall and--more importantly--had an identically configured Boston Acoustics Recepter Radio just a couple of feet away. Neither radio had any trouble pulling in the local megapowerful FM stations, but the Boston exhibited a notable advantage with smaller college stations; the Radio 705 exhibited more static, and in a few cases (WFMU in East Orange, New Jersey; WSOU in South Orange; and WBGO in Newark), the Cambridge was barely able to lock on, while the stations were quite listenable on the Recepter. AM reception was similarly average on both radios. The 705's tuning dial was generally accurate and easy to use, with the yellow/green tuning lights offering more assistance on FM than AM. That said, we preferred the precision of the Boston's digital tuner--and its ability to offer station presets--over the old-fashion analog dial.
In terms of sound quality, the difference was less pronounced, though we'd still give the edge to the Boston Recepter. That radio delivered a weightier sound, with a more natural sounding midrange. And while it delivered better sound than the average $30 radio or boom box would, the Radio 705 sounded notably thinner when compared to the Boston model--in short, it sounded more like the small tabletop radio that it is. That said, the Cambridge model was able to get considerably louder than the Boston, so it would have the advantage in noisy environments such as a kitchen. The Radio 705 also offered the tone control knob to emphasize the low or high frequencies, which helped even out the sound when listening to certain radio stations. We didn't mind the monaural sound, since stereo speakers in such a small unit wouldn't offer worthwhile separation anyway; the headphone jack does offer stereo playback, however.
