Hi all - wish I had a house with a separate listening room without a TV in it so I could enjoy music while her indoors watches the box........anyway, until that happens (it won't!) I need to get a set of decent headphones and amp, without breaking the bank, and have my eye on the Grado SR60s and the Creek OBH-11. Does anybody have experience of this combo and are the SR80s worth spending the extra on? Thanks - DD
