I have just bought the Sony f886 walkman and am using it with an audio technica ATH-ES55 and an AKG K451 (among others) .
My question - do I need to upgrade my headphones to get the full benefit of this hi-res audio walkman? If I do, what should I be considering?
As a lot of headphones can be bought at discount, the sky is the limit in terms of suggestions.
Thanks in advance !
