I am currently running Swan speakers from a Marantz 7400 for HT usage. While I really enjoy the sound of this setup, I was thinking of trying to add something extra to the sound. I was looking to utilize the Marantz 7400 as a pre/pro, and then add a power amp. I was looking at the Outlaw 7100 or Rotel 1075. I am trying to keep the cost under $1000. Though a 3 amp setup would be just as fine vs the 7 and 5 amps setups of the Outlaw and Rotel. Since I am not adding a big time power amp, any thoughts on if I would notice a difference given that the Marantz is a decent mid-level receiver, or will I be getting "true" power from these amps and would notice a difference? Thanks for any input.
