Based on specifications only, seems to me a Denon 3805 or Yamah 2500 will get you more for much less. Those E855, with 89 dB sensitivity, probably can do better with more power. If you believe this warm and bright thing, then Marantz may be the one for you because there seem to be no shortage of people claiming Marantz receivers have a warmer sound. To me, when you get to the mid-fi stuff, most of them are closer to neutra as they should be. The 7500 does seem to have a nice signal to noise spec, if the pre-amps in it are of high quality and quiet, then you could add an external amp whenever you feel like having more power.
