You have picked the two amplifers in Munich that were in my top three systems at the show. (Actually, the Apex gear was featured at the HiFi Deluxe show offsite)Would be fun to compare the Gryphon Apex with the Robert Koda K160 monos. As an enormous fan of Gryphon and owner for nearly 12 consecutive years before Robert Koda (also pure Class A), I can imagine their Apex is truly fantastic.
I am quite familiar with the Gryphon Sound having owned the Diablo 300 and frequently enjoying the occasional whisky with a client who owns the Mephisto Monoblocks.
And while I'm not sure what speakers or market segment the new Gryphon Apex series is designed to serve (I'm not completely sure, but I believe they are appoximately 1 tonne per monoblock with 1 million pure class A watts into 1 ohm ) but for sure Gryphon's signature 'Velvet Glove in an Iron Fist' brand aesthetic was present in spades.
