I guess you will eventually learn that amps don't, and shouldn't make your system sound much different once you get pass the point of diminishing return. The question is how long it will take and how much you would have spent by then, on various amps. There are some exceptions, such as some (not all) tube amps and amps like Carver's. Apparently (I am not 100% sure), Mr. Carver might have designed certain amps to have a "sound signature". In true, those amps may not be totally transparent, and whether they would sound better or worse than a transparent amp such as Anthem's, will depend on the individual's taste, and/or compatibility (matching?) with the individual's equipment (preamp, speakers etc.).
