I just finished auditioning amps and can without a doubt tell you they sound different. What I can also tell you is that it is like choosing your favorite ice cream. Not sure one is “better” than another, but that you need to find the flavor that you like.
And I can also see how after a few years it might be good to change it up a bit.
