I'm deeply impressed by the B&O BeoLab5 speakers, by their price ticket, but even more so by their performance. To me their major surplus value lies in the automated speaker calibration, which rather efficiently cancels out the effect of the room they are in, and of their position versus walls and corners (thus augmenting their WAF).
I read the NAD DD 390 amp has a likewise feature.
My question: is there something like a "stand alone automated digital room correction device", that can be linked in the chain, somewhere between source and speakers? Examples? Any experience?
