Anyone technical that can help?
I’m currently using a pair of headphones rated at 24ohms input impedance with a 10w practice amp rated at 8ohms output impedance. It sounds absolutely terrible (hissing like crazy) through headphones (fine when used with just the amp).
I’ve read some websites that state to avoid distortion you should multiply the output x8 (so in my case headphones with 64ohms).
Is this about right? I was looking at the Sony MDR7506s which have 63ohms but wasn’t sure if I need something lower.
