Notwithstanding Audiooracle's opinion to the contrary, IME, if you're using a subwoofer (or subwoofers) when you listen to music, you are FAR better off ditching any tube pre-amp (specifically including your CJ) for a pre-pro. Seamless subwoofer to main speaker integration is a snap with the modern bass management software found in any good pre-pro and (again IME) next to impossible without it. This delta will - as far as I'm concerned - swamp any other benefits of a good tube pre vs a good pre-pro. OTOH....
Your particular circumstance is complicated by your (apparently) exclusive use of analog source material (which would see both ADC and DAC in the pre-pro), as you have no CD player listed in your system. Also, while your 1.7s provide good bass performance without a sub, you already have a subwoofer. Given that fact, I gather that you prefer to use a sub with your 1.7s for music. If true, I suspect that you'll be happily surprised by how much better the system sounds when you switch out the CJ for a pre-pro, even for 2 channel listening.
In any case, you've assembled a quirky hybrid arrangement - an all analog rig that begs for audiophile style treatment (including tubes) and a multi-channel rig (including a subwoofer) that begs for a more high tech pre-pro with bass management. Personally, I'd use a pre-pro every time were I in your shoes, but I also understand how weird that might seem with for a vinyl centric listener.
