Pre/Pro, Amplifier for definitive system

Hello, this is my first post. My system includes bp10b f, clr2000 c, bp2x r, 100tl s, pioneer 53tx rcvr, jvcxv721bk dvd a/v, monster 2500 p-cntr. O.K so some of that is relative to my inquisition. Dilemma being that of course it should sound better, right! I beleive that my main problem is with the rcvr. I enjoy the sonic signature of the pioneer but it lacks the current to drive my speakers, especially the cntr channel. Not that I am now going to be snobby about integrated equipment. I know their is a lot of great stuff out there but when I upgrade it will definitley be to seperates. I would also like to get matching equipment so a good balance between the quality of the pre/pro and amplifier is greatly desired. Any feedback is going to be appreciated since this is my first time entering the forum community. Thank you
