[please excuse my bad English]
@ryder M30 - rolled off treble and sounds excessively warm and dead // not heard
M30.1 - sounds brighter and more open but still warm
M30.2 Anniversary - sounds brighter and more open
M30.2 XD - ?? (no experience with this one) // idem; not heard
I totally agree. I heard neither the M30, nor the M30.2XD though. But I know the M30.1 and 30.2 Anniversary very well, as I owned the first, sold it it, and upgraded towards the latter.
I second too the finding that one can upgrade to a component which sound sweeter AND delivers more details, as you noticed. This simply means that the more detailed but sweeter speakers have a lower distortion rate.
I describe my M30.1-->M30.2Ann upgrade hereafter.
The
Stereophile measurements of the M30.2 Anniversary -made with the grilles ON- suggest that there is no treble or high-mid emphasis at all on the M30.2 Anniversary. There is even room for a very little bit more energy in the high-mid (around 3KHz).
I sincerely hope that
@brylandgoodman (OP) is relieved now...

- I owned
Harbeth M30.1 (a bit too rosy-view but lovely; medium & treble a bit too muffled), sold;
- upgraded to M30.2 Anniversary (present); better speaker; sound a bit more "monitor", but still very musical. I love them.
