Does the nano iDSD measure: Good, Bad or Ugly?
Some of you have enquired as to how the nano iDSD measures* – under conditions similar to those by recognised industry bodies/magazines.
The following are our laboratory measurements of the behavior of the iFi nano iDSD using the Audio Precision System Two.
Based upon the above setup, we made the following four measurements – these
follow closely (though can never be identical) the typical industry approach as used by leading audio magazines. One should allow for tolerances in the findings but there should not be any large discrepancies.
Just as an example, take the Total Harmonic Distortion (THD) measurement of the nano iDSD:
Measurements conducted THD Comment
By iFi 0.02% -
By audio magazine ‘A’
0.03% to 0.05% Perfectly acceptable small variance
By audio magazine ‘B’
0.15% Measurement error/different methodology?
*Notes:
i. Measurements though scientific and objective, are subject to errors and honest mistakes.
ii. There is no scientifically proven link between “better” measured performance automatically equating to better sound.
Therefore, please bear these points in mind when you read THIS and ANY other measurements article. As always, listen for yourself and let your ears be the judge. Measurements are just that, measurements.
Well, we have crunched through a bunch of numbers and summarised the 4 key ones most often referred to.
Short answer: it measures pretty well for its class. There are no numbers that are untowards.
Long answer: Please follow the link below. The in-depth blog is here:
