Looking at amps -about to test drive an Ashdown ABM C115-300 EVO II Combo - £569 to pick up from local Soundcontrol. They haven't got the C115 - 500 in local store at the moment. My current combo - a 300w Trace 7215 SMC - has always been loud enough for me so far. Should I save the £180 and go for the cheaper Ashdown? It is Christmas after all - extra presents for the kids!
