I bought this to replace an XtremeMac Luna (original version), when I discovered that it wouldn't work fully with my new iPod classic (120GB). Among other things, I needed a unit with a display that all but disappeared when the bedroom lights are turned out (it's amazing how many of these things don't offer this most-basic option). Obviously, I also wanted something that would work properly with my new iPod. Since I have a somewhat longish history with Boston Acoustics, I decided to give their offering a shot. Glad I did: Like the Luna, there's a lot of well-thought-out design touches, a few of which are undocumented (several have noted the "hospitality" setting that limits the maximum volume level...some units apparently shipped with this setting engaged, leaving the purchaser to believe s/he received a defective unit). Unlike the Luna, the Duo-i offers greater versatility in terms of input/output ports (for starters, a rarely-seen headphone jack, and an honest-to-gosh threaded coax connector for connecting a serious antenna, even though the tuner is sensitive enough to make do with the included wire antenna in most instances). There's also a "Service" USB port in back of the unit, which hints at the possibility of updating the unit's software/firmware, something that would have come in awfully handy with the Luna..
And while the Duo-i doesn't look quite as svelte on one's night table as a Luna (or most iHome models, for that matter), this can be pegged down to the size of the Duo's two speakers, which are considerably larger than competing models. In terms of table-top audio, the old Detroit axiom of there being no substitute for cubic inches kicks in hard: unless you throw megabucks at it, no amount of bass equalization will get you to the quantity, let alone quality, of bass that most music lovers will find satisfying. BA, intelligently, simply went for a larger enclosure and a pair of 3-1/2" drivers in a ported enclosure, aided with just the right amount of EQ (and made further-tweakable via user-adjusted bass/treble controls). These efforts certainly do justice to the listening experience, putting the Duo-i in a different league from most any other iPod clock radio I've come across.
Controls: I happen to prefer having a few knobs I can twirl to a surfeit of tiny buttons. Boston smartly splits the difference with three multi-purpose control knobs with rubberized surfaces and high-quality tactile feedback, which also push in, button-style, to activate multiple features. Added to this are one button each for the two separate alarms, plus five buttons for station presets (ten FM, five AM), and you have comprehensive control without the flight-simulator look.
Radio reception: this one's easy. The Luna's reception on most stations was sub-par to the point that I rarely listened to radio through it. The Duo-i is just the opposite: it's so good that it rivals my main hi-fi tuner's station-grabbing abilities!
The straight skinny: this one is a winner, and a keeper.
