kilohms. thank you. I have not looked at many other power amps (specs) but 22 is the lowest I've seen. Hopefully it gives you some measure of what -might not be- quite enough impedance.I don't think I mentioned that I'm using XLR interconnects (2 channel). The 2 channel DAC is sounding very good @ 30-ish hours.
