audioengine A5


The audioengine A5 (also known as audioengine 5) is a set of stereo hi-fi speakers. Delivering excellent quality, along with an extremely solid and sturdy design, they're some of the best hi-fi speakers we've seen to date. Everything about them screams quality - from their custom design, to the sheer power at which they're able to output sound, the A5 is a top-notch product.

Audio performance on the A5 is the best we've heard yet on a pair of hi-fi speakers. With a well-balanced range, the A5 delivers audio of any genre with exceptional clarity and definition. During testing, we were enthralled by everything from Puccini's Madama Butterfly to Jimi Hendrix's All Along the Watchtower to Outkast's GhettoMusick. From the soaring vocals in Madama Butterfly, to the throbbing bass of GhettoMusick, every note was clear, sharp and well defined. Even more impressive, the A5 is capable of maintaining this clarity at very high volumes. The only problem that we noticed during testing was that treble tended to be ever-so-slightly flat at the highest ranges. Everything else was exceptional, however, with sharp, thumping bass and a clear, crisp midrange.

One of the most impressive aspects of the A5 is the sheer power that it's capable of outputting. We found a comfortable listening level at about 25% volume, and didn't dare go much past 60% for fear of damaging our ear drums. Throughout this entire range, we didn't notice any diminished clarity - this is actually the first hi-fi system where we've hit unreasonably loud volumes before noticing distortion. The inbuilt 5" woofers deliver powerful and thumping bass, although the lack of a separate subwoofer means that you won't get that vibrating rumble.

Already impressed with the speakers' music performance, we decided to hook them up to our home entertainment setup to see how they fare for home theatre use. Again, we were overwhelmed. Watching Full Metal Jacket, every yell from Gunnery Sergeant Hartman, every thumping chopper rotor, and every gunshot and explosion, came in crystal clear. The A5 had no problems at all handling both the bass-heavy firefights and the accompanying musical score at the same time, and it easily rivaled some of the better home theatre systems that we've seen. Although they're only two-channel (ie, not surround sound), the A5 speakers should appeal to any movie lover.

Everything about the design of these speakers has been geared towards delivering the best possible audio quality, and what's more, it's been done without compromising aesthetics. Coming with a solid black or white casing, the speakers are actually quite heavy, and even at the highest volumes, the rugged design prevents noticeable distortion from vibration. Audioengine has really gone all out with the design here, even to the point of using a Kevlar woven composite in the woofers (Kevlar is the material used in a lot of modern body armour). Although we weren't able to do any tests to determine whether or not the woofers are bulletproof, the sheer amount of volume they're capable of producing without distortion is testament to their durability.

The back panel of the main speaker is a simple affair, with power outlets, copper wire outputs that go to the other speaker in the pair, and 3.5in stereo input jacks. The volume knob is located on the front of the unit, although there's no separate knobs for treble and bass, and no remote is included, which may be slightly irritating, especially for users planning to use the A5 as home theatre speakers.

Overall, the audioengine A5 is one of the best hi-fi systems we've seen thus far. Capable of handling anything from opera to R&B to movies, it comes highly recommended to any user in the market for high-quality, powerful stereo speakers.

NU CineTrek WDR041


This portable DVD player from NU is an excellent option for those looking for an affordable device for in-car DVD playback, provided that they don't mind substandard image and audio quality. We're not being facetious either; quality is what we look for in massive LCD and plasma television sets, not seven inch portable DVD players. While image quality does suffer on the Cinetrek, it is in fact a very viable choice for in car entertainment.

At 200mm x 148mm x 26mm, and weighing under a kilogram without its battery, the Cinetrek is one of the more portable 7" screens we've seen. It doesn't utilise the folding form factor of other players, such as the Shinco MDP-1770, but is instead a single flat panel, much like the VOXSON SL-77. This is a pretty welcome change in our opinion, giving the player a lot more portability, at the cost of a few controls which are replicated on the remote anyway! A fold out stand is available for sitting the Cinetrek on a desk, or similar surface. Overall, we were quite impressed with the WDR041's design, our only complaint being that the buttons located below the screen were quite difficult to press, but they're on the remote as well anyway, so it wasn't a major issue.

Operating the player is really quite simple - provided you don't lose the remote. The minimal buttons on the thing itself aren't really sufficient for watching DVDs. The remote itself is incredibly thin, no more than two centimeters, and very lightweight - so much so that it was actually uncomfortable to use for the first few hours, it just didn't sit in the hand properly. With over fifty buttons, however, the remote packs plenty of power, and actually delivers more functionality than a lot of home entertainment DVD players we've reviewed.

Up to this point, the Cinetrek had really impressed us. This changed when we inserted a DVD. The image quality was utterly appalling. A poor contrast ratio made several movies (for example, the darkly atmospheric The Crow) unwatchable, while others were simply poorly defined. A 480x234 resolution exacerbated image quality problems, as did relatively weak colour support (fleshtones were quite unrealistic). To its credit though, the screen was exceptionally bright, and provided several image adjustment options which lessened (although far from combated) the display problems. An exceptional horizontal viewing angle (we noticed almost no colour shift even at the most extreme possible angle) makes the Cinetrek suitable for multiple viewers, although even a few degrees shift vertically renders the already struggling image quality into an unwatchable mess. Finally, a decent response rate made action movies quite easy to watch, with surprisingly low levels of ghosting.

Audio quality from the supplied speakers was reasonable, and the volume range quite adequate - perhaps lacking a little at the higher end, but audio remained audible throughout. Since the player doesn't actually come with its own headphones, we plugged our own Audio-Technica A900s into them, and experienced what is quite possibly the worst quality audio we've ever heard. A consistent buzzing noise drowned out most of the other imperfections in the audio, and made prolonged use essentially impossible. This sound was replicated with other headphones we tested with the device, although the fact that they were all rather high-end, expensive headphones led us to the belief that an inability to drive the headphones due to insufficient power was the ultimate cause of the problem, which wasn't present on lower end earphones.

Despite its problems, the bottom line is that the WDR041 is designed for in-car entertainment. It even comes with a pouch that can be hung on the back of front seat headrests. For this purpose, it's pretty adequate. Keep it at eye level, don't lose the remote, and avoid dark movies, and the Cinetrek will be a welcome addition for your passengers.

Ruckus Wireless MediaFlex VF-2825


The Ruckus MediaFlex wireless router, while not technically a media streamer itself, is a device intended to facilitate wireless streaming of media (videos and music) throughout the home. The easiest way to think of the MediaFlex is probably as a way of 'unwiring' wired, or Ethernet based, home networks. If you have long trails of Ethernet cables running from your PC, through your living room and to your home entertainment setup, then the MediaFlex presents a convenient way of eliminating them. With a strong focus on streaming media, and minimising distortion and interruptions, the MediaFlex is also a potential solution for those whose current wireless network is unable to cope with the demands of wireless media streaming.

Paired with a MediaFlex wireless adapter, the two MediaFlex units essentially replace the bulk of network cable running between two products, for example a PC and an Ethernet-enabled set-top box. So in this example, you would connect your PC to the MediaFlex router via Ethernet, and then your set-top box to the MediaFlex adapter via Ethernet, and it would be as if you'd run a cable straight from the PC to the set-top box. The only difference is the lack of an unsightly cable on the floor, waiting to be tripped over by the kids or chewed to pieces by the dog.

In theory, it's quite simple; however, in practice things become a little bit more tricky. Anybody who's ever set up a wireless network before will know how finicky they can be, and unless you're a networking guru or lucky enough to have it work instantly, expect to spend a bit of time making sure all your settings are correct. Still, that's part of the price of dealing with wireless networks, they're very rarely entirely simple affairs.

One of the big selling points of the MediaFlex is its wireless fidelity. By using a multi-antenna system, it claims to be able to detect and determine the best wireless path, avoiding disturbances and interference. We didn't experience any performance issues while streaming content throughout our offices, which are fairly open-plan, but have an industrial-strength air-conditioning unit installed. However, no two environments are identical, so how it performs in other types of environments will vary. Nevertheless, based on our tests, the MediaFlex may provide a viable solution for users whose current wireless network is susceptible to interference.

The design of the router (and the almost-identical adapter) is quite elegant, being shaped sort of like a ... well, we're not sure really. Although the spinning green light, which is located on the top of the unit, could be an annoyance in a darkened home theatre room. The router comes with four Ethernet ports and one WAN port, while the adapter comes with a single Ethernet port.

For users who wish to unwire their currently wired home entertainment network, or who are simply looking for a way of reducing interference, the MediaFlex router and adapter combination from Ruckus is worth considering.
