Hi folks, i've owned the Diablo 300 for a year and now sold it for a Vitus SIA-025 Mkll.
I was surprised at how much difference there is between them.
The Vitus delivers much more current than the Gryphon, i was shocked.
I now have a much deeper and cleaner bass on my power hungry Thiel speakers.
Regarding musicality, engagement and body it's not even funny how much better the Vitus is vs the Gryphon.
I've been told that the SIA-025 Mkll is even more musical than the SIA-030.
SIA-030 is more powerful and faster but not as musical.
