Well, I appreciate the info and feedback since you tried it both ways, but I know that subjective sighted A/B tests are extremely prone to cognitive bias.
MP, yes, but not pennies. I have designed Class A, AB, D, and multiple topologies within. I also have experience with DC-DC converters, analog, high speed digital and mixed signal design at levels that put most audio requirements to shame. I have spent a lot of time testing audio equipment with top of the line and industry standard APx555, Rohde & Schwarz UPV, etc. Unlike most people, I've done ABX testing at various levels of THD and IMD from vanishing to near clipping.
The amplifier is rarely the big problem if it's not clipping, unless there is DSP in there. Which is why I asked. Obviously changing the speakers only when the DSP is tailored for that setup is going to give wrong results.
