Lucky for you George!
You can continue to let test equipment judge how audio gear sounds for you.
Yes, that in conjunction with listening, repeated and measured over and over if necessary is the only way to get the best.
"snake oil" voodoo should be kept out of it, as most of it is only praying on the technically challenged, hoping they’re gullible enough to spend the big bucks on cheap fancy lable’d rubbish that does nothing.
Cheers George
