AVI is moving inexorably away from being simply one of the better names in hi-fi.

Although AVI still produces its standard - and very well received - range of electronics and loudspeakers, it seems that the company is now intent on leading the charge in bringing computer music into our little fold and, in the process, raising the standards for computer audio in general.

The forward observer for this conquest of digital downloads was the little Active Neutron loudspeaker, however this merely surveyed the battleground for digital's true champion, the ADM9.

On quick inspection, the ADM9 looks and feels like little more than a good, solid stereo standmount speaker, albeit one with active amps built in.

The front-ported two-way with its 25mm soft dome tweeter and the 165mm paper cone bass unit looks surprisingly traditional and works best on 60cm stands when positioned about half a metre away from the side and rear walls.

That said, the ADM9 remains firmly in the 'not fussy' camp when it comes to placement. You could happily plonk them on a bookshelf and still get most of the performance you will get from obsessive 'quarter of a millimetre to the left, please' type installations.

A closer look at the ADM9 reveals some differences from ordinary standmounts, though. The first difference is found in the amplifiers behind those two drive units; two bipolar designs, the first being a 100 watt model for the tweeter, with a 250 watt unit for the bass driver and an active fourth-order crossover sitting in front of them.

Look closely at the back of the right-hand speaker and you'll see the rear panel has five solid gold-plated phono sockets (with just one in the left speaker).

One of these connects the left and right speakers together, and a five-metre length of phono-to-phono cable is supplied for this purpose. Two of the connectors act as inputs for an analogue line source, while the other two are outputs for a slaved speaker and a subwoofer (a matching subwoofer with a front-firing 250mm bass unit is also available).

The speaker also includes a rudimentary one-source preamplifier, which can be controlled by using One For All's Audio Zapper remote control that comes supplied with the ADM9. The controls on the Zapper are limited to volume up and down, mute and source selection, however these are standard Philips RC5 commands if you want to invest in a more fancy remote.

A one-source analogue input active speaker is not going to drive the digital download revolution on its own, but that all changes with the strange square socket marked 'digital input'. This is a USB 1.1 socket and behind it sits a Burr-Brown digital converter. And it's here that AVI has been doubly canny. The

USB port allows you to access anything that is digitally recorded and stored on a PC or Macintosh, be it a quick download of the new Killers song whipped off iTunes, a carefully worked Exact Audio Copy-enhanced, AccurateRip-validated bit-for-bit recording of your CDs stored on your computer, or even a FLAC-encoded Studio Master from Linn.

The 'doubly canny' bit comes in when you connect an analogue source to the ADM9, as it allows the USB port to pass those analogue signals back through to the computer, for ripping and storage. In other words, if you have a good record deck and phono stage, the USB-equipped ADM9 will turn those two into an analogue remastering centre.
