"We live in a world where the top professional studios use pretty much the same computer/software systems as those of us further down the food chain. The main area in which pro studios are better specified than project studios is in terms of what's hooked up to the front and back ends of the computer, and the audio interface is a very big part of that. Yes, you can buy an audio interface with twice the I/O at half the price of the Quartet, but the converters and mic preamps will probably not sound nearly as good. On many of them, you can hear digital crosstalk and interference from the USB connection grumbling away in the background if you need to run the mic amps at a high gain setting, as you might when using a ribbon mic. I tested for this on the Quartet. Recording ambient room noise with a passive ribbon mic at very high gain settings, and then normalising the result, showed up only room sound and a little honest electronic hiss. There have been occasions when trying this test with lesser interfaces has produced a result reminiscent of a fax machine being fed through a coffee grinder. When judging the value of something like the Quartet, you have to factor in what it might cost you to add decent mic preamps to a more mundane interface, and also the cost of a separate monitor controller. You also have to consider logistics: where is everything going to fit? The Quartet provides a compact solution capable of true 'big boys' performance, and the minuscule quality difference between it and those truly esoteric devices costing 10 times as much really is in the realm of 'But will it affect record sales?'" - Sound On Sound
