Looking for a high end integrated to suit Dynaudio contour 5.4's

Gryphon Diablo 300.
Nothing like it. So far, one of the very best I've ever heard and absolutely reasonable price for the level of performance.  Least of all for being a true all in one.

If it's heading off into Porsche 911 money then it's a no contest and the Porsche wins every time ;-)

In the under $50k bracket for separates or integrated, the Diablo 300 is right there.

At this level the diminishing returns are REALLY small.

Haha, Yep, its quite a list! Thanks to all audiogon'ers for the input.  Time to get the dart board out and start throwing.

@plb02, the Dart would be another good option if you can find a pre-loved example 😉 - https://www.dartzeel.com/cth-8550/

Very special synergy with Dynaudios, great high current amp that punches way above its weight.
