... or are we just mugs with too much money? Gotta ask this one on behalf of my little bruvver who has seen the shininess that is the Sony 555 av amp. Will he benefit for the upgrade from a Marantz 4200? What do you people who just taken the plunge on buying big boy amps? (3803s & 2011s in partic seem to have been bought in numbers) - worth it or will the glow only last as long as it takes you to hoover up the polysyrene. I've advised him to think long and hard about it - i'm not convinced that a change from a mid price amp to an expensive one will yield much benefit - but I don't own one. Arguments about music v AV are not an issue as this is purely for AV.
