If you are comitted to buying Vienna Acoustics, then your two amps do deserve an audition.
The Rowland Model 2 will have lovely synergy with the speakers, and may even be sufficiently powerful for much orchestral music or rock, unless you need full-blast orchestral music or live rock sound pressure levels.
The Plinius, being a Class A design with stiff power supplies, should do well on the Mahler.
Please report back to us on how it sounds when you get everything hooked up and broken in.
