Null Test Difference - test to measure real fidelity of a device

On these pages there are often discussions on the SQ of a device, quite often DACs.
Sometimes - we must admit - such quality is "in the ear of the beholder".

My partner (Tom Gefrusti) and I have been employing a new test to objectively outline the real fidelity of a device in dynamic conditions with micrometric precision. I am talking about how a device behaves during music reproduction, not a static test, taking values directly from its analog outputs.

To see an example of this test you can visit a review of mine of MSB USB Power DAC at: http://translate.google.com/translate?u=http%3A%2F%2Fwww.nexthardware.com%2Frecensioni%2Famplificatori-dac%2F558%2Fmsb-technology-usb-power-dac_5.htm&sl=it&tl=en&hl=&ie=UTF-8

(Unfortunately, it's only a Google translation)

Incidentally, such test has started the making of a new DAC database where all measurements will be compiled. Many more DACs to follow.

Comments are welcome.
