Well, if your sound is "harsh" with that system these are the reasons;
1a. You have some unnecessary power "enhancement" device between the amplifier and the wall outlet.
1b. Room Acoustics, including to big a room for the speaker amplifier combo...ie amplifier clipping.
3. The Wadia is too bright for your tastes.
4. Weird Speaker cables like MIT or Transparent or a bizarre basement creation.
5. Something is broken
6. You never liked your speakers in the first place
*wildcard reason* you listen to harsh forward recordings and expect different results from your system.
The last thing you want to do is mess up a perfectly good system with an AR or a CJ preamp. Properly working YBA gear is the least of your problems I assure you.
