When I wanted to streamline my computer speaker setup, which included an old Onkyo receiver and a pair of JBL Control One bookshelf speakers, I began looking at stereo and 2.1 computer speaker systems from makers like Logitech and Klipsch. But ultimately I wasn't interested in replacing the JBLs, which I originally chose because they were "real" speakers I could use with a receiver/amp of my choosing. Though I certainly had the physical space to continue using the Onkyo receiver, it was admittedly overkill in terms of both power output and consumption. So I began looking at small form factor amplification, quickly finding the the only real contender was the Dayton DTA-1. The device is actually a re-badging of the Sonic Impact T-Amp, which had a strong following among audio enthusiasts until the company decided to make some significant changes to both its design and pricing. Fortunately for us, Dayton stepped in and re-released the original, with a few minor modifications. Those familiar with the company know about its legendary "Tiny Mighty" subwoofer that offered great performance at an amazing price. The DTA-1 carries on this "bang for the buck" legacy, and, considering its size, is probably the most deserving of the "Tiny Mighty" nickname.

Measuring six inches wide and weighing just over a pound, the DTA-1 is really a miniature marvel, handily driving the JBLs in my nearfield desktop setup, but also doing incredibly well with a pair of more sizable loudspeakers in my living room (though it looks a bit odd for a large set of speakers to be connected to a device a fraction of their size). Rear speaker connections use standard spring clips and the single source input uses a 3.5mm stereo jack. A 12V AC adapter powers it all, but for those interested in taking the show on the road, the amp also runs off eight AA batteries.

The portability factor is actually pretty compelling. Where before I might hesitate to haul over a receiver to a friend's house for a party or movie night, I can just pack up my entire desktop setup with minimal hassle. Sure, it's only analog stereo, but in mobile setups I rarely need more than that. Connected to a laptop, iPod, or standalone optical media player, it is sure to impress everyone from audio neophytes to veterans. Used as I have it in a desktop setup, it more than does the job, offering clean and robust amplification in a highly compact and unintrusive package.
