I am looking to get a new power amp for my system...Musical Fidelity M6 CD player, Parasound JC2 pre amp and Paradigm S100 speakers. Ive been recommended the Parasound A21 but not sure about it...one issue is that i live in western australia so not much opportunity to test drive......other options that i could listen to are Bryston, Vincent, AudioLab and Rega. Anyone got any suggestions...my budget in aussie dollars is around 6K...for info the A21 retails in Australia for around 4K.
