ohlala is right.
also, mccormack might be an upgrade over the adcom. but don't expect miracles; synergy is the key. without knowing the rest of your system or musical tastes or room size, etc., it's hard to make recommendations.
also if you really need 250 watts per channel then be prepared to spend more than $2k to get significantly better sound at the power level.
Often, a lower specification will sound better most of the time. For example, a superbly designed 25 watt solid state amplifier (like the Aleph 30 or some such) will sound better than the adcom, but only if the rest of the system is capable of revealing the differences!!
