Long time advocate of DSP here. To the 'purists' I say, vinyl, cd mastering(usually very different), mastering engineers have preferences and systems. Most recordings are digital and will have bounced in and out of ad/da conversion, bounced to analogue tape and back into digital at the whim of the producer/engineer before you even get to hear it..
High end pro DSP is to all intents transparent.
I stated this in another thread but will repeat; the solution arrived at in response to a particular subjective shortfall in the LF capabilities of the Everest involved supplementary 4x 18" sub drivers-there is no way that 'solution' could have been arrived at/built into the Everest design deploying as it does 2x 15"'s. Buying the wrong speaker for your situation is just silly and cannot be laid at the door of the Everest design.
