I have heard the PBJ's and I think that if you upgraded to the Kimber Hero's or Van Den Hul for instance for interconnects, esp. cdp, you would smooth out your system quite a bit. Also try Van Den Hul speaker cable for a smoother sound. The PBJ stuff can tend to be a little bright and forward. It's also not shielded very well so it can catch interference easy.
Good luck.
