The Gryphon Apex proves there's no end in sight for cost, size and weight of the amps that manufacturers will design and build. I'm not sure I understand the audience that would need an Apex. My Gryphon Pandora pre and Antileon EVO Stereo amp control my Rockport Altairs better than any amp I've ever owned. I likely haven't tapped into more than 25% of the Antileon's power capabilities as I run it most of the time in the medium bias setting.
At 450 pounds, you need some type of floor jack system to get it in position for the amp stand. Gryphon didn't bother putting handles in the rear knowing they'd be useless.
I'm a bit confused on the cost. I see $120,000 mentioned for the Apex stereo version. According to this article, the Apex stereo costs
82,500 Euros which coverts to US$93,750 -
