RE: Pioneer made great integrated receivers back in the day...

Hi !
very interesting point here
" HD 800s are 300 ohm cans. So they deally need to be plugged into an output with an impedence that is <30ohms ( using the 10:1 rule of thumb). However the resistor network that is used to reduce the amplifier output to suit headphones may mean that the 'phones "see" a comparatively high impedence that is unsuitable from a perfectionist viewpoint "
I have seen from a schematic that the Pioneer sx1050 headphone outs are obtained from the speakers out adding in series a 150 ohm resistor (one per channel).
So maybe the big bass perceived is just an underdamped bass ? bloated ?
Just asking.
