I did an extensive A/B listening session with Diablo 300 and Luxman 509X paired with ML 11As (using same source components and cables). The Gryphon sure has raw power, but found it to bright on some few songs, borderline fatiguing. Some songs sound great, others sound a tad harsh. First impressions of the Diablo 300 compared to the Luxman 509X was that something was off with the Diablo. The 509X had less bass impact but was smoother across the board. This of course is my opinion specific with the 11As. I am sure others may like it.
I had a similar experience the first time I heard the Diablo 300 at another dealer, again paired with the ML 11As, this time with DCS components as source.
