I do not under stand what to look for in numbers… can some one dicribe what I need to not have to turn up the volume too much?
My cheap phones need to be turned up to about 66% with 32 ohms.
Will the larger amount of ohms need more volume to run them?
what do the technical specs say? why can’t I find them easy…
