We are all crazy!! I think you would be on the higher end of the scale if you get other speakers before you really put the 804s to the test. Do you not like them for Jazz and Classical? They are some of the best speakers on the market for almost any use and I will bet they meet your needs. Pair them up with the Fathoms in a 2.2 arrangement. The 990 will get you there and you won't need more amps. Get some CDs or SACDs and go to it.
