I think the DX sounds like an ipod. It was accurately described by early reviews and myself as very dry /neutral. Now the selling tags and new updated opinions are on it's musicality
I use ma-900 and EX1000 which have huge stages maybe biggest in their respective head gear categories and I found the DX to be average.......... Dry and neutral and musical have been term used up until 2017 to mean
different presentations of the playback.
Neutral meaning what it means, no noted emphasis
Musical meaning perceived dynamic differences in some parts of spectrum i.e. more punch in bass, vocals with emotion, spaaaaarkle in the treble, indications of NON neutrality.
Cannot be musical and neutral...not until recently anyway
read the new amp specs and they were clear to mention it kept the musicality bull
