Methodology:
• Only difference is 2 channels vs 32 ch DA converter outputs from DAW to summing mixer.
• Identical signal path, calibrated with test tones.
• No added gain or other manipulation in post production.
Conclusions:
• There IS a difference in sound.
• Despite same peak levels, OTB version average loudness in between those peaks is greater by approx 0.3 dB. Does that imply that ITB is losing some detail by crunching all the ones and zeros through just two channels, whereas OTB retains detail by spreading the math load across more converter channels? I don't know. You tell me. But whatever you (or science) tell me, I know which version I prefer.
The video:
I'm frequently asked if investing in "Outside The Box" (OTB) analog summing is worthy. This video will help you to use your own ears and decide for yourself. I calibrated *everything* to ensure an apples-to-apples comparison. Each individual track was calibrated, and peak levels are identical on the mix bus meters. I mixed the f*** out of the digital version, and am happy to put my name on it. But the analog version is more pleasing to me. Feel free to disagree with my preference--and let me know why in the comments.
If you don't hear a difference, you can thank me because I just saved you a pile of money and hours of research. On the flip side, if you do hear it, and it's important to you, start saving your dollars and vent your frustrations to my manager instead of directly to me! :)
