I currently have a Beresford TC-7520 dac fitted with a level 4 mod from Audio Upgrades,for details of what was done look here http://www.fidelityaudio.co.uk/beresford7520.shtml I`m considering a change and would like advice/opinions on what to go for that would provide better performance. It was suggested that the modded Beresford now has the capabilty of a dac in the C.£1000 range and it certainly is very good to my ears but you know how it is,I`ve got that "could I squeeze a bit more out of my system" feeling again!
