Spend most of your time at your desktop? Tired of crappy computer speakers? Desperate for some genuine desktop hi-fidelity? Look no further.

HIGH QUALITY DESKTOP audio comes in two basic shapes. There are those speakers that are elegant and stylish, with cabinets that either make a design statement or are minimalist in nature. The second kind is basically a set of scaled-down standmount speakers. Cambridge Audioโ€™s SLA25 desktop speaker system falls into the second category โ€“ the proportions of the cabinets, the layout of the drivers, right down to the removable hi-fi style grilles. Theyโ€™re even supplied with a set of sponge bungs to damp the output from the rear mounted reflex ports โ€“ condensed hi-fi indeed.

Features and Construction

The SLA25โ€™s are very well built units, with a solidly braced MDF cabinet, and they look really good in their gloss black finish โ€“ if you like black boxes on your desktop, that is. For some buyers, the form factor and conventional looks are going to be a turn off compared to the smaller, swoopy, laid-back silver metal cabinets of Missionโ€™s Pulse desktop speakers (review coming soon).

Being a hi-fi nut, I had no hassles with the SLA25โ€™s occupying pride of place at my work desk, and of course, I whipped the grilles off immediately to reveal the 4-inch woven polyfibre mid/bass driver and 1-inch soft dome tweeter. If youโ€™re clumsy or have kids or pets around, then that tweeter is going to take a beating, particularly in a desktop environment, but if youโ€™re careful, then the grilles should come off.

The SLA25โ€™s are powered units, with a 30-watt amplifier housed in the right speaker, along with the inputs and connections, which are all rear mounted; this is no problem as long as you leave the various cables permanently connected. A set of standard speaker cable binding posts is used to hook up the left speaker and a length of cable is supplied for this purpose, but USB or 3.5mm cables are missing in action.

Thereโ€™s a 3.5mm input, an RCA line-in, an input for CAโ€™s own iPod docks and the all important USB input, which allows users to run their computers directly into the speakers, skipping the computerโ€™s built-in DAC and allowing the (presumably) higher quality DAC in the SLA25โ€™s to convert the digital signal to analogue. Thereโ€™s also an RCA subwoofer output if you want to add some weight to the overall sound, perhaps with one of CAโ€™s Minx subwoofers, but thatโ€™s pretty much superfluous given the on-board bass abilities.

No remote control is supplied, and the only user control is a volume knob that doubles as a standby switch on the right speaker.

Sound Quality

One of the benefits of taking hi-fi style speakers and making them smaller is that you get hi-fi style sound, just reduced in scale. Then again, the fact that youโ€™re located so close to the speakers in a desktop environment mean that they sound just like big speakers.

With a claimed frequency range of 60Hz to 22kHz, the SLA25โ€™s go plenty low for desktop speakers, especially with the reinforcement from the desk surface. Siting them right against a back wall brings in way too much of a contribution from the reflex port, and thatโ€™s when the aforementioned bungs come in handy. Thereโ€™s more than enough muscle in the amp, which combines well with the bass on hand to offer a real sense of power and impact. Playing Dave Matthewโ€™s โ€˜Gravediggerโ€™ from the Some Devil compilation CD (from the drive in my MacBook Pro) and pushing the volume right up showed that the SLA25โ€™s can generate serious sound pressure levels without falling into distortion or compression. Sure, if you push it too far, theyโ€™ll harden up but at that point, youโ€™ll probably need earplugs. At more normal volume levels, thereโ€™s a sense of delicacy, cohesiveness and high-resolving capabilities to the sound, just as youโ€™d expect from what is effectively a set of mini-monitors in a near-field environment.

Their ability to go loud means that the SLA25โ€™s are ideal for other uses besides their obvious desktop/computer speaker orientation โ€“ theyโ€™d add a lot of gravitas to the sound of a flat panel TV, although an optical input would be a nice touch here to allow easy connectivity and access to the DAC. Theyโ€™re also ideal as the foundation of a compact hi-fi system in a small room.

Going Hi-Fi

I tried the SLA25โ€™s mounted on a set of stands, fed by my Pro-Ject Dock Box Fi (reviewed here) and was impressed. There was no doubt that I was hearing a true hi-fi level of sound quality โ€“ even with the iPod hooked up using basic cables, the SLA25โ€™s were sonically way ahead of most any iPod speaker systems Iโ€™ve heard, even the bigger and more expensive ones.

I was intrigued, so I pulled out all the stops and laid out some more serious gear. The SLA25โ€™s were placed on a pair of Monitor Audio stands ($999), hooked up to my Marantz SA8260 SACD player via a set of Nordost Blue Heaven II interconnects ($600) and connected to each other with a single 3m Blue Heaven II speaker cable (half of $1530, I guess). There was also a Blue Heaven II power cable running into the Marantz ($340). With the speakers about 60cm from the rear wall and over two metres apart, slightly toed in, the sound quality was more than just impressive โ€“ it was outstanding, considering that the amp and speaker cost is only seven hundred smackers.

The bass was commendably tight and the low-end weight was more than adequate. While thereโ€™s definitely an audible contribution from the rear mounted reflex ports, itโ€™s not dramatic, and overall, there isnโ€™t the sense of a big bass boost at the bottom that you might expect from speakers this small โ€“ CAโ€™s engineers have tuned these little boxes very nicely indeed. The midrange isnโ€™t recessed; in fact these speakers arenโ€™t at all laid back. Rather, theyโ€™re a tad forward sounding, but that makes them an exciting listen. Treble quality was something of a highlight โ€“ thereโ€™s no brightness or harshness. In absolute terms, thereโ€™s a degree of solid-state graininess to be heard, but thatโ€™s not an issue. After all, youโ€™re likely to hear the same and more on pricier speaker/amp combinations. Detail levels were also notable, and the sound stage was wide and deep, with imaging that was quite precise โ€“ at the price point, they put on a very good show.

Conclusion

I shouldnโ€™t have been surprised that these speakers turned out to be as good as they are because Cambridge Audio has access to a substantial speaker manufacturing concern in the form of Mordaunt-Short. As desktop speakers, the SLA25โ€™s are a treat, and as long as their size and looks work for you, then theyโ€™re an excellent choice. As a small-room hi-fi combo, they make for some lovely music, and thatโ€™s without any fancy accessories โ€“ even with the supplied cable and my cheapest interconnects or a 3.5mm cable, they sounded good. The USB input definitely sounds better than the 3.5mm feed, which makes them a neat choice for a basic computer audio solution. Iโ€™d love to see a remote control added to the package to make them user-friendlier in a hi-fi environment, but even as they are, the SAL25โ€™s are a very easy recommendation. ASHLEY KRAMER
