No matter the topology of an amplifier each will have it’s advocates and invariably detractors, no exceptions. SET has been the most satisfying choice for me, yet certainty OTL or class A solid state for others. There’s variation and a hierarchy within each specific topology. I could never proclaim or bestow "best " for any of them. You listen and eventually you’ll find what suits personal preference and objectives. So many variables, all SETs don’t sound the same. Listen to for example OTLs, Atma-sphere, Einstein Audio, Joule, Tenor each has it’s own sonic signature. This is true for any and all amplifier genres/topologies.
