hi all. firstly i have an ipod 80gb and igrado headphones, and i,ve converted my cd collection using the apple lossless format, and very satisfied i am with the sound quality. but i am curious as to know which direction to take to achieve a truly great hi fi sound through headphones. how can i go one better? i remember some guy asking what hifi for advice on a great sounding system using headphones as the listening source, and if i remember rightly you said the rega aollo cd player and the creek obh-21se paired with the grado sr60's. i already own a pro-ject head box mk11, so what budget set up would you reccomend. also how would i change bass, treble ect, because most headphone amps don't have that option. many thanks. danny. p.s. also what cables would you recommed to connect system up with.
