Very quick impressions on three portable amps for the UERM:
Written in a stream of consciousness, whatever thought comes to my mind, sort of way. All observations are specific to the UERM and PS Audio Perfect Wave (w/ bridge) DAC.
Meier Audio Stepdance
Warmish. Very clear. Lacks bottom two octaves in bass. Fail. OK I'm done; next amp please.
P.S. A little scratchy in treble on occasion.
Nice tone. Wow this thing digs and digs into the music. Authoritative. Not as clear as stepdance, a little bit thick, but that's OK since it suits my preferences – never thought live music sounded “clear” anyways. No trouble with treble scratchiness - yet capable of bite. A rare combination of two good attributes. Nice impact. Great bass. Hitting the low stuff. I guess the people who say it's good know what they are talking about. This is the most similar sounding to my reference amp - the BA.
