Sorry if this is a stupid question but I'm new to all of this hi-fi stuff. I have a Sony receiver (STR-DH510) and it says that it outputs 8 ohms. I also have Sennhieser 558's and they are 50 ohms. When I plug my headphones into the receiver using the headphone out, the bass is extremely increase and its very annoying. Why is this happening and how can I fix it (other than using the eq)?
