IMS Electronics Hybrid Valve Headphone Amplifier Review

” Looking at the picture of the circuit board on the IMS website, I suspect the highlighted SMT caps couple the OPA2134 to the output jack. This implies that the opamp is not directly coupled to headphones and the opamp does not have a bipolar supply. This not necessarily a bad thing, but in my opinion direct coupling is better; the best capacitor is no capacitor.”
