Thiel Owners

^Not all Pass Labs are suitable for all Thiels.

I had the proof that Thiel speakers are not the bottleneck in a system when i compared my Gryphon Diablo 300 to the Audionet Humboldt in my system.

My Diablo 300 felt like a broken amp compared to the Humboldt driving my CS 3.7s.

That's how much of gap there is in sound quality between the two amps, insane.

I will keep on upgrading the pre-power part of my system for sure in the future.

^Interesting. For $55K the Humboldt's specs don't impress, especially for a load like the Thiel CS 3.7's. The Humboldt is rated for 320 Watts into 8 Ohms / doesn't come close to doubling down with 460 Watts into 4 Ohms and is not spec'd into 2 Ohms at all. The less than half the price Diablo on the other hand is rated for 300 into 8 Ohms doubles down to a greater and more linear response of 600 Watts into 4 Ohms (the CS 3.7's actual nominal load) and 950 into 2 Ohms. With the CS 3.7's 4 Ohm nominal / measured 2.4 Ohm minimum load and recommended power of 100 - 600 Watts (into an 8 Ohm load, with the understanding that the amp could double down as necessary) the Diablo appears to be better suited. For much less than $55K one could easily find separates with more apparent appropriate specs.

I have the 2,4 and when I use mu XA200.5 with them they are a different speaker. 

I use the X600.5 for the 7.2 as they just have the power to handle that load and play in a 35'x60' living room.

Right On!  Spec(s) are a starting point. Still, numbers do not tell the whole story.

Trust your Ears.

Happy Listening!
