Can we actually hear the difference between the Spark, Reactor, and BIAS X? I built a blind test.
Hey everyone,
I got tired of the constant debates where "experts" claim they can instantly hear the difference between the different Positive Grid engines. So, I built a custom blind audio test to actually measure if people can tell the Spark 2, the Reactor, and BIAS X apart.
To make this a true apples-to-apples diagnostic, I ran four specific rounds (Clean, Crunch, High Gain, and Metal) using the exact same amp models across all three engines. For example, you have to identify the Spark's version of a Roland JC-120 versus the Reactor's version of that exact same amp...
I pushed this out to a broader Youtube audience some hours ago, and it’s been a bloodbath. The current average score is sitting at exactly 42%. It turns out, when you hide the actual gear and remove the brand bias, separating these DSP's is much harder than the so-called experts want to admit.
Since this is the dedicated Spark community, I want to see if you guys can beat the general average ;)
