As I already previously mentioned in another thread, to my ears the Gold, no make that "Platinum", was Stradivari with a neutral and ballsy amps. Of course much depends on your personal taste and preference as well as room acoustics. Take that with a grain of salt and let your own ears decide.
Here is just an example of the Strads with Pass Labs amps. The room acoustics of the first room are terrible (and that was the point of the video) but you can hear how much resolution and finely detailed nuances the Pass Labs are pulling from the Strads. Because the Strads are a bit darker sounding speakers, a neutral sounding amp typically hits the sweet spot. I've heard the Strads with Krell, Bryston and a few others. McIntosh will be similar but Pass Labs will typically give you more goosebumps from the extra resolution and finesse they can bring to the equation if the overall system and room allow for it.
