Hi chaps, I am just starting to save for a new pair of headphones. Initially I was thinking of going for the HD650s but having heard the HD700s for the first time today with the HDVD800 I'm thinking I might sink a bit more money and go for HD700, HE500 or TH600 for example. My current set up comprises a Schiit Magni and an E-DAC(basically ODAC) and I was just wondering if the headphones might be considered 'too good' for my DAC and amp. Would I be disappointed having only heard the HD700s with Sennheiser's amp when I made the step down to the Magni?
TL;DR - Is there some sort of DAC/Amp:Headphone price ratio you should abide by? Is there a level of headphones at which point you'd consider them too good to use with the Magni for normal listening?
