From the the different opinions I always see on this topic I'd say it depends on your system.
In my system upgrading from an AV SS integrated amp to a high end 2 channel SS amp made a minor difference.
Different preamps made much bigger differences in the sound quality for my system. Tube preamps were the sweet spot for me.
I've heard huge differences by A/Bing tube amps in systems. So I'd say yes for tube amps. Not near as much in SS amp A/Bing.
I'd want horsepower amps for inefficent speakers like planar, but for the other types I haven't seen much of a difference in different SS amps.
