What is the sonic impact of violating the 1/8th rule with matching headphone impedance to amplfier output impedance? Does the bass get mushy? Distortion? Is it linear where the worse the ratio is the worse the sound? I have an amp that has an output impedance of 10 ohms and headphones that are 50 ohms. I am wondering if it is worth switching to an amp with an output of 5 or lower. Is that a big enough mismatch to consider changing amps or am I being concerned over nothing?
