The Threshold is rated at 100 watts per channel pure class A at 8 ohms. It is capable of outputting more but above that it shifts to it's class AB mode. I had it tested at a local dealer once and they measured 320 watts per channel before clipping onset at 4 ohms.
The Threshold sounds wonderful on those Thiels but the XPA-1 sounds more dynamic..especially at higher levels. I still have the Threshold in my system and available if I want to use it, but the Thiels are normally hooked to the XPA-1's.
Because of an unstable job situation I need to wait on any purchases, but I think the XPA-1 should go back on my short list. Even though I don't need the power, the control they seem to offer would be an asset. The fact that your Thiels can sound bright depending upon the electronics used gives me some perspective also, as they don't
sound that way with the XPA-1. My Mirage M3-si speakers aren't bright-sounding, so perhaps they'd be a good fit with these amps.
