I did an A/B demo of G68/98 with G55/B&W802D and then the same front end with M's DSP 7000s.

Obviously this is my ears, but I thought the all M setup was an awful lot better. I don't like the B&Ws at all....lots of people do though! I can go into why if you want.

Classe amps are very good, also listen to the Krell multichannel range and Parasound too.

If you can arrange, try and hear the kit in your room, rarther than in dem rooms - if your spending that much, it's well worth doing!
