George Necola, Gearslutz:  
"Before starting my review and go into details let me say this: you will never get as much bang for the buck as with the PM50s. The performance (price/value/sound) ratio is enormous or to describe in some candidate words "It's always good to be underestimated".

I estimated a lot and they deliver.

The PM50 are like a mixture of ATC midrange, PSI highend and Barefoot lowend. I am not going to compare 500 US$/pair monitors to monitors that cost 10 or 20 times more.. what I am going to explain is that you get the most balanced product on the market."
