I auditioned PM8006, Audiolab 8300 and CA CXA81, with an assortment of speakers. TBH, not a very systematic audition, nor a very lengthy one. I felt 8300A to be very punchy and lively, CXA81 a bit smooth and PM8006 neutral and detailed with a weee bit of roll off. It sounded more mature. For my listening ie classic rock, heavy metal and western classical, it was the right balance. It's ability to scale up with orchestral pieces was impressive.
But I recon, for pop, techno, EDM, Audiolab would be better.
Everything boils down to your taste and music that you listen. And of course, the speakers you use.
I couldn't compare the soundstage and imaging as much, but at home, PM8006 in combination with Dali Rubicon 6 FS speakers it has beautiful 3D soundstage, reasonable but not very precise imaging. Dynamic range is awesome, suited for classical. Very detailed, but for a critical listener, the very top end roll off is noticeable. Especially for cymbals, hi-hat and triangles. Bass is extremely agile without any booming. Recently one FM who was visiting my home, didn't believe me and kept searching for a hidden SW..
Obviously these are attributes of the whole system, in which my speakers play a huge role.
