Keep in mind that the Thiel 3.7's don't just dip into sub 4 Ohm loads, they live there over most of their operating conditions. That's why I caution those to be wary of amps that merely claim to be "Stable for musical transients". Thiel's recommended power was 100-600 Watts per channel, but that was for a standard 8 ohm load with the understanding that the amp would double down as needed into the actual load. Into a nice, safe rounded 2 Ohms that would be closer to 400-2400 Watts. Keep in mind that as the impedance drops so does the sensitivity. So that 400 Watts minimum might seem like an awful lot, but, for adjusted sensitivity; it's about the same as 100 Watts into 8 Ohms. Some of the amps you previously mentioned are indeed robust, sturdy amps with most speakers and then some, just perhaps not ideal into your particular Thiel 3.7's. I couldn't find more recent independent measurements of Pass Labs current offerings. While I suspect the more recent ones might be better in this regard, I also suspect that these older ones are not irrelevant. As much as I like some of their gear, their independent measurements have been somewhat disappointing of late. I tried to include this before but for some reason it wouldn't take.: https://www.stereophile.com/content/pass-labs-int-150-integrated-amplifier-measurements |
Despite the perception and reputation that these designs might have, I’m not sure they’re the ideal candidates: https://www.stereophile.com/content/thiel-cs37-loudspeaker-measurements https://www.psaudio.com/products/bhk-signature-300-monoblock/#tab-specs Pass doesn’t spec their amps into 2 Ohms, only suggests that they’re stable there (though not for how long). https://www.stereophile.com/content/pass-labs-xa160-monoblock-power-amplifier-measurements |
