No mistaking it, today I got The Sound using the MA-9S2. LF gestalt is here, too; it's just a matter of warming up the amp and getting the speaker(s) dialed in. This means I am good to go, to use this amp for a reference, and to make the most of it.
As for "methodology": Yes, I did do some "research" in order to come up with a list of candidates to "audition". Nonentheless, I am amused (and pleased) that a class A/B SS amp with boatloads of "feedback" can do what this one does (for me). Now, flush with this success, I have half a mind to try class D amps for side channels!
