Why my system has detail but no body & warm vocal?


My system:
B&W 602S3
Rotel RA-972 int amp
Rotel RCD-975
Kimber 4Tc speaker cord
Kimber hero interconnect

When I listen to Barbra Streisand or Lionel Richie's song, it has detail but no body. The vocal is thin and laid back.

What is my weak point? I am thinking about try Audio analogue Puccini or Arcam A75 amp, and try Arcam CD72 CD player. Is it a right direction to go?

I seriously auditioned a rotel(1o60) system before buying my current kit. I listened alternately with the b&w 602 s3's and then dynaudio 42's. There was a very disernable difference in the way these two speakers were making music. the b&w's had mesmerizing detail to them. the dyna's seem to present a warmer and more you are there, real mid range. I think that rotel does sound like very solid state but excels at an upfront real presentation with plenty of warmth in the mids. try tubes or different speakers.
You may be shocked at how bright the Rotel sounds. I would start with amplification changes for the largest overall change by far. Ouch, Rotel is sharp.
I own the Rotel 972 and woudn't call it lacking in body. Reviews back this up.. it's weakness lies in it's very warm bass. But that B&W tweeter is way too bright.
An integrated amp is a good starting point however if you want a full bodied sound (with warmth) as you descibe, you have to think big! Lose the Rotel int. and get separates! such as a nice tube preamp and a big powerful SS amp. Maybe invest in big, full range floor standing speakers. I have this type of setup and regardless of what type of music I listen to, it never lacks in body, warmth or musicality. Then tweak the system to "your" liking afterwards.
I also have the 602 s3 speakers and rotel ra-02 amp and 02 cd player. The most important thing is the placement of the speakers. The tweeters are a bit bright. I use some older no-name multi stranded speaker cable for the tweaters. For stands i use my own diy made solid brick stands. This really kicks donkey. And yes there is cement between the bricks.
