Monitor Audio uses very good crossovers. But....most audio shops use 2 dimensional amps. They will sound like many other.
When you use an amp what can give a deep and wide stage it changes. That is why I only sell amps which can give a wide and deep stage.
Pass Labs is one of the best brands in highend poweramps. Because they can give a wide and deep stage. But also the class will let you hear all the differences in timbre.
Just read the reviews. Audio is all about how you use it.
From 2007-2009 I sold a lot of Primare with Monitor Audio in a shop I did run at that time. I could send my clients to any other shop to listen to: B&W, Dynaudio, KEF, Focal, Dali etc.
Because for that money all other shops sold 2 dimensional sound.
It was so much fun, people came and said often: But we do'n't want 2 dimensional sound. It is very easy to teach people the difference between 2 and 3 dimensional sound.
After that the overall sound does it's work!
