arcam a80 power amp

[markpne19]

got an a 80 amp with my b&w 603.3 just wondered if any one could tell me if buying the power amp and bi wiring the speakers would be a noticible upgrade

just wondering is there any one out there that has done this with the arcam

would you say its worth spending £400 on a power amp or sell my current amp and use the extra money to upgrade ?
