Certainly some DBTs have positive results. E. Brad Meyer did tests many years ago in which the results were that a tube amplifier and a solid state amplifier sounded different. Stereophile did a poorly run blind test between a tube and a SS amp and got a positive result, and later, a university prof did a better run DBT with the same kinds of amps and got a much more definite positive result. Indeed, in amplifier reviews, Stereophile publishes a graph showing the frequency response into a simulated speaker load. Many tube amps have a high output impedance, and so into many speaker loads they do not have a very flat FR.
Determining whether there was an experimental error and trying to see if the results can be replicated are part of scientific method.
