I've heard Genelec on many occasions, because they're pretty common amongst studio guys. Funnily enough the brand has been criticised for having a house sound that's too flattering for serious "real Scotsman" studio work. Not once has this been confirmed by measurements and it might turn out that Genelecs speakers are just that - good. As for Putzey's work - I find it interesting to say the least. He prefers using phase linear filtering in his loudspeakers, which has its pros and cons. There's a reason why our plug-in has both minimum and linear phase. In filtering there is no free lunch, you just need to choose what you can afford to pay.
