http://www.soundonsound.com/sos/nov00/articles/lynx.htmpretty feature-packed card.. which ive read had a very professional following
It's a PCI soundcard which, although it uses onboard A-D and D-A converters rather than a separate breakout box, is designed to yield the best possible audio quality. It features a single stereo analogue input and output, and its analogue signal path is as simple as possible, to keep noise levels to a minimum. Switching between professional and consumer levels is done using just about the cleanest approach there is — relays with gold-plated contacts — and the hardware uses surface-mount active components and precision resistors for optimum performance. Extensive use of ground planes and power-supply filtering also keep computer-related noise to a minimum.
Single stereo digital inputs and outputs are also provided (although all four inputs and outputs can be used simultaneously for four-in/four-out operation when required), as well as word clock In and Out, two MIDI Ins, and two MIDI Outs. On the digital side, great attention has been paid to the onboard clock, which provides very low jitter levels, and the digital input and output are, unusually for a soundcard, provided in AES-EBU format, although S/PDIF is also provided as a software-switched option. The digital input and output are also transformer-coupled to combat earth loops.
Final Thoughts
This is possibly the best-sounding soundcard I've reviewed to date, even though it doesn't use the very latest converters. It just shows that attention to detail and dedicated audio engineering can squeeze the last drop of performance from the available components, and that you don't necessarily have to have externally mounted converters to achieve professional results. The Lynx One's digital interfacing is also versatile and well-thought-out, and you should be able to connect it to most digital gear (except for those items with Toslink optical connectors).
Some musicians will be put off by the lack of 96kHz capability for analogue recording and playback. However, the difference between 16-bit and 24-bit recordings is far more than that between 44.1kHz and 96kHz ones, and unless the rest of your gear is of excellent quality I doubt that you'd notice more than a whisker of difference.
If you only ever need to record and play back in stereo, the Lynx One will do this in style. Although its retail price is comparatively high, you should be able to hear the improvement in sound quality when compared with many other soundcards, and if you look around you should be able to find it at a UK street price of around £449. You can get multitrack soundcards with external converters and an impressive-looking rackmount case for a similar amount of money, but those who use their ears rather than their eyes are likely to be more impressed by the Lynx One. Anyone who remains convinced that computer soundcards are the poor relation of audio should take a careful listen.
