Lewm you are correct it's a perceived feeling of perfect pitch and yes this was hard to initially tell until it was heard and then it's easy to understand. It's like most people don't understand or hear polarity but once understood I can tell if a song is in or out of phase.
Listen to an SME 10 then a Lenco or most DD tables and you begin to understand having a correct speed is extremely important to the sound of a piano. I'll be the first to admit I never understood this until I moved away from a belt drive table myself and with the help of others opened my ears and it all became clear.
