I'm looking to upgrade my entire HT when we move into our new house. Speakers will probably be the Axiom M60 6.1 HT package, with either an SVS or Hsu sub. Room is 14 1/2 x 23 x 9, open on the long side to the living room. I've been considering the following Yamaha v1400 or 2400 Pioneer Elite 53TX or 55TXi Denon 3803 H/K 525 or 430 vs. Anthem AVR20 I intend to power the system with either 2 Earthquake Cinenova Grande 3 channel amps, or a comparable 6 or 7 channel amp, such as an ATI, Outlaw, or Sherbourne, etc. Of the receivers listed above, will any of them compare to the Anthem, or more specifically, is it worth the extra $$$$ to upgrade to the Anthem.
