Hello, I just have got a Samson CO2, a microphone pair costing about 130 € in Europe and 140 $ in USA, which I found sounding good in a comparison on a steel string guitar involving many other microphones costing up 5000 $ as a unit, within a test proposed on internet. I tested a 'low end ' recording chain consisting of the Samson CO2, a pair of low cost cables (a few €/$ per cable, Pure Sound Cable brand), and Edirol FA-66, a PC audio interface including two microphone inputs, costing less than 300 € in Europe and less than 300 $ in USA, in comparison with a 'high end' chain. I will not tell what are the elements of this chain because I do not want to make bad advertisement for these brands that I am respecting a lot. Such a test is only representative for my recording application, similar to the one of most people who submit recordings here. The microphones in this 'high end' chain are considered by many recording engineers as the best ones for classical piano; their cost is more than 20 times the cost of the CO2, the cables costs about the same like the CO2, the microphone preamp is hand-made in USA and acknowledged as one of the few best ones worldwide, the PC audio interface that performs the A/N conversion is 3 time more expensive than the Edirol FA-66. This 'high end' recording chain costs about the same like a German upright piano... I thought that this test could be of interest to some members of this forum. It is not intended at all for convincing them that they should spend such a crazy amount of money like the cost of the high end chain for recording their pianos. As an opposite it intends to show that the sound quality from what can be be got for a price that is not negligible but affordable for most of us, is not that far from what top audio gear would provide on the same piano in the same room with the same microphone placement.
