The SR80's are great cans.....they do rock & blues very well indeed......great bang for the buck.
Grados are much easier to amp, but still benefit greatly from an amp with good synergy.
The HD650 scales really, really well....the better the amp....the better they sound.
For Grados and a Senn 600 series.....the Mad ear kicks some serious *****.....you just need to roll tubes from Grado's to Senns and the synergy from both are off the hook
