Quirky British Audio

I can understand that British monitors might have a certain style, but can anyone explain why UK amplifiers might sound a certain way or perform better with certain speakers?

Lately, I have been experimenting with ATC monitors, using the "cheap as dirt" Behringer amps. This sounds so good that I have been thinking about upgrading to more serious amps including Brystons.

Googling around, several reviews have suggested that these power hungry speakers actually didnt sound so great with high powered Brystons, but quirky, underpowered British amps including Quad and Rega did a great job.

I never loved the looks or functionality of my Naim Nait integrated, but I have to admit it sounds suprisingly good when used with my Epos M12s.

What's the secret with these UK electronics?
