Are you testing the amplifiers at all listening levels? I find that many amps do sound similar or the same at low levels but when pushed the shortcomings are apparent. I start my testing with something dynamic.
These shortcomings can almost always be measured so you need to challenge yourself by using a scope more often and do some frequency sweeps. More advanced hobbyists may use equipment to check distortion.
Can I hear a difference between a Hammond OPT and a Slagle or Monolith OPT? The answer is hell yes and they all measure different as well.
