We all know that microphones sound different, and not just by a little. And we all know phono cartridges sound different, and not just by a little. And don’t get me going about the differences in loudspeakers!
What all three transducers have in common is the nature of their operation: mechanical.
Our sound systems are all lorded over by one, two, or all three mechanical contrivances that so greatly affect sound quality.
Fact is, between the differences in microphones, phono cartridges, and loudspeakers it’s impossible to ever suggest there’s a “standard” of performance we could ever rely upon.
It’s no wonder every system sounds so unique.
