I 1st decided on a few methods/guidelines to rule out any false impressions.
- Analog generation source.
- Same signal to all converters.
For the sources I recorded some late night noodling of Analog synth/drum, Rhodes, & Udu drum. I also took a random cross selection from my Vinyl collection (via a kab 1200/apt holman for the curious audio geeks). This gave me a wide range of content to listen/judge.
I split & recorded the signal into the analog line inputs of a Lynx, API, TC, & a MBox. All levels are roughly matched to within .1dB.
The files below are the 24bit/48khz recording from the four converters. Download the files, can you hear a Night/Day difference? Can you tell what is what?
A/D Conversion, can you hear the difference?
