Will replacing an Emotiva DR3 with Parasound A31 be an upgrade?

You may want to think about Schiit Vidar also since its getting a lot of love by reviewers and is more recent in amp design. I'm in the market shopping for a new amp myself,

found this Stereophile article helpful with its brief reference to general sound qualities of different class solid state  amplifiers. It does pay to know the impedance characteristics
of your speaker and look at technical reviews of how the amp performs as speaker impedance changes in the audio spectrum.
