Having recetnly changed my integrated amp to a rega elicit-r I am now after some advice re headphone amps. I have a pair of Grado SR125 headphones and am looking for something up to about £300. The obvious choice seemed to be the Rega Mk11 headphone amp but actually this does not seem to feature on any recommended equipment site so I am not sure how it would perform. Does anyone have any experience of this combination? Other options in this price range seem to include Graham Slee novos and some beyerdynamics and rhinelanders but nothing seems to stand out so again feedback would be welcome!
