Customer Questions & Answers


Previously, I submitted a question:  What is the output impedance for this amp?  Their answer is:   Hi David.the output impedance is 150-300Ω.Thank you.    150-300Ω is the load impedance that is supported by the amp, not the output impedance. What I want to know is the output impedance, which is the impedance of the amp output. I am trying to figure out what the damping factor would be with my headphones if I use this unit.
