It will cost you $600+ just to retube a Mac amp. Maybe look at Proceed or Lexicon or Anthem or Rotel separates. You may be able to get a good 5.1/7.1 pre pro and a warm sounding 5 channel amp combo here on the Gon.
As far as Mac goes, I would forget it unless you increase your budget significantly. Newer gear from the above mentioned brands may sound better than the really old Mac gear that may fit into the $2000 budget. I am not trying to steer you away from Mac (I am a proud owner of tube pre and mono blocks), it's just that Mac ain't cheap, and their gear tends to hold their value fairly well over time--meaning that even the older gear is not inexpensive.
