I currently have a pair of very old Sennheiser eh250's which while sound ok, are a little muddy and now need new pads. They also make my ears VERY hot after just 30-40 minutes listening. So I'm considering buying a new pair of cans, but want something that will closely reproduce what I have already. Current kit: Quad L-ite x 4 Quad L-ite centre Denon 1909 AVR BK Monolith 300W subwoofer PC / PS3 / 360 provides audio over HDMI (I figured the Denon DAC will do the processing, so this shouldn't actually matter that much) But I'd also like to get the best possible sound out of my iPod (everything is at 192Kbit MP3). Granted I'm not expecting the low end of that subwoofer from any sub £300 'phones. I use my iPod at the moment with a pair of Sennheiser CX400 II and think they sound good enough. Will the Grados be an overkill / waste of money?
