I've been reading about amps lately and usually people tend to lump brands together by general characteristics you find in most of that brands line. I was hoping some of you could share your thoughts on what brands of amps offer what different qualities. An example would be I've heard people say Bryston are powerful and offer a strong low end. Or that it doesn't typically matter how old a McIntosh is, they are solid performers in all areas. I know this is all opinion. But then again, isn't everything in audio?
