As you can see from my sig. I can play movies big and loud, but when the wife and kids go to bed and I want to listen to music it has to be headphones. Currently I have a pair of slightly worn Sennheiser HD520 II plugged into my Yamaha DSP-A2 amp. What I need is advice on how to get the best sound for music. I am currently intending to buy some Sennheiser hd650's, but what else..... Should I buy a better lead and what about a dedicated headphone amp ? What are the gains like in having a headphone amp ?? help please. As for budget... no idea but as a guess, once the new headphones are paid for (Approx £250 ??) I could spare another £250 but as I say thats a guess.
