Yes I see that now you don’t like detented vc and dual mono they are a pain to some. But as far as being more dangerous because of power delivery, not so.
As your amp say for theoretical example has 10 x gain on it's intput driver stage, and when/if your source goes faulty dc to 2v or someone yanks an interconnect, that would be a total of 20vdc to the amps output stage and speakers, survivable.
Slip an active preamp in with another 10 x gain, and you have 200v theoretical volts going to the amps output stage and speaker. Everything gets smoked.
What’s more likely to fry amp and speaker, 20vdc or 200vdc?
