In addition to Internet radio stations and podcasts, the GDI-IRD4400M can also access Pandora and Sirius. Pandora creates custom radio stations based on what music you like and finds similar artists; we're fans of the free service and think this is a great added feature. Sirius subscriptions run $13 a month. The online music storage service MP3Tunes is also supported, although we did not test that functionality.
In addition to all the online music services, the GDI-IRD4400M can also stream music off a connected PC. File format support is solid, including MP3, WMA, Real Audio, WAV, AAC, and AIFF. Surprisingly, the GDI-IRD4400M also played our Ogg Vorbis and FLAC files, even though they're not officially supported. We've had trouble in the past getting Reciva-based radios to reliably stream, but we had better success this time with the GDI-IRD4400M and a PC running TwonkyVision software.
One of our favorite added features over 2008's ITC-IR1000B model is the Bravado's ability to stay connected to the wireless network even when you turn it "off." The result is that when you turn the GDI-IRD4400M on, it starts playing music in just a couple seconds--most Wi-Fi radios take considerably longer as they reconnect to the network each time. The downside is the GDI-IRD4400M sucks up some power while off, but we're guessing most users will appreciate the feature.
You can also set up to five alarms on the Grace Bravado. The options are flexible, allowing you to set different alarms for the weekends and weekdays, and the ability to tune into basically any music source as your alarm (or a standard beep). The Bravado isn't set up as an alarm ergonomically--there's no snooze function or the ability to quickly change the alarm time--but it may work well enough for some people.
Additional connectivity is a bit sparse. There's an analog stereo output, for connecting the Bravado to a separate stereo system. Next to that is a headphone jack; we would have preferred if it was located on the front panel for easier access. Unfortunately there's no auxiliary audio input, so there's not an easy way to plug in, say, a friend's iPod in a pinch. There's also no Ethernet jack, so you're stuck using Wi-Fi.
While this feature set is excellent on Grace's less expensive, step-down models, it's less impressive on the $200 Bravado. At the time of this review, the Logitech Squeezebox Boom costs about $60 more, and includes much more functionality, including additional streaming music services (Rhapsody, Last.fm, Live Music Archive, and Slacker), more file format support (Apple Lossless and WMA Lossless), and an auxiliary input.
Given that the Bravado is actually slightly less featured than the step-down GDI-IR2000, the main reason you'd spend more money is for better sound quality.
First off, we compared the Bravado directly with Grace's entry-level ITC-IR1000B. The ITC-IR1000B is mono radio, but we've always had a soft spot for its surprisingly satisfying sound. Switching between the two radios, it was obvious that the Bravado had a significant advantage in bass response, as the little ITC-IR1000B doesn't put out much low-end. The Bravado also does a better job of filling a room with sound at louder volumes, although at more moderate volumes the positioning of its speaker is a drawback since the sound likely won't be pointed at your ears. Overall, the Bravado definitely won the head-to-head matchup, but the difference isn't as large as you might as expect, mostly because the ITC-IR1000B sounds better than its small size would indicate.
Next, we stacked the Grace up to the excellent Squeezebox Boom. We started off with "Pick It Up, Lay it in the Cut" by Sharon Jones, which gave both systems a good workout in terms of bass response. We had originally tweaked the EQ to provide a little extra bass on the Bravado, but we had to scale it back as the bass distorted right away. Neither radio sounded great with this track, but the Boom sounded less strained and handled the low-end with more finesse. Next up was "Queen Jane Approximately" by Bob Dylan, and here the radios were closer matched. However, when we cranked the volume, the Boom again had the edge, as the Bravado started to sound a little harsh.
Like virtually all Wi-Fi radios we test these days, the Bravado had no dropouts or buffering issues during our testing. As always, wireless networks differ significantly depending on the exact environment, so performance can vary significantly. Luckily Grace offers a 30-day money back guarantee, so you can fully test the GDI-IR4400M in your home environment without any risk.
