The BasX A300 amp and PT 100 preamp received editors choice awards from the UK magazine Hi Fi Choice. Associated equipment for the review were Cambridge CXC transport, Chord Hugo dac, and ATC SCM 40 speakers. So, the supporting cast was well above the price range of the Emotiva pairing which should lay bare any faults from the amps.
The test concluded with "a new pre-power amp price benchmark, the most convincing evocation of affordable high-end that I've yet encountered and as a result an unequivocal great buy".

I myself have no personal experience with these amps. Just relaying some info generally not accessible in the US.
