This card is not only clean but it has some of the quietest electronics I've heard in a PC card. I use this for acoustic measuring with a microphone and it has more dynamic range than my mic. I also use it as an accurate AC voltmeter and as an oscilloscope device to measure raw speakers before they go into cabinets. It has over 5 volt input capability which means it does have 100db of dynamic range. The output is also Audiophile grade when playing lossless media such as FLAC or WAV files. Very high quality and I don't need a separate preamp to play music through my amp. I recommend this card if you are looking for a card to use with ARTA, HOLM, Speaker Workshop or any other similar software package. It's perfect.
