Aragon Soundstage or Conrad Johnson PV-14L

I started with home theater and am a newbie trying to intergrate 2 channel audio. Here's where I'm at.
Onkyo TX-DS777 (5.1 A/V receiver) now using as a pre/pro
Classe CAV-75 6 channel amp (RCA only)
Classe CDP-1 CD player (RCA, Bal & AES/EBU Dig.)
Toshiba SD-5109 Prog. scan DVD (for now)
Joseph Audio Fronts biwired W/DH Labs (planning to upgrade to Cardas)
I/C's are XLO except for 1 set of entry level Cardas RCA-RCA (Classe CDP1-Onkyo)
I am concidering the Aragon Soundstage(used approx. $1850) or the CJ PV-14L (Around $1500 used). Both have HT bypass. Should I buy one of these or replace the Onkyo with a multi-channel pre/pro and separate tuner. I cannot spend any more than 2K at this time and would not mind spending less.
Any suggestions on any changes would be greatly appreciated.
