Hi Johnny,
First, congrats on buying Tom's 250. A decision you will never regret.
Onto your question. If your system use is split between 2 channel audio and watching dvd's (or other surround sound modes) in a five or seven channel configuration, that would rule out the "purist stereo only" preamp. However......
there are stereo pre's that have what's called a "theater bypass" that would allow you to use your stereo pre for two channel listening, and have that pre send the audio to a surround sound type device. You can then use your Pioneer for the later and buy a stereo only pre if you do or want to do serious 2 channel listening and assuming you have the funds. From a "sonic perspective, that would be the best option.
FWIW and I'm sure others will chime in, I recently sold my Conrad Johnson Premier 18LS for about $1,300 (initial retail $4K). IMHO, an outstanding, musical piece of gear for that amount of money.
If dedicated two channel is not that important and assuming:
1) you want to use your Odyssey's for both purposes, and
2) your proportional split of stereo vs multi-channel is somewhere in the 50 - 50 range, or more prone to multi - channel use, stay with the Pioneer at this time.
In the future, you can consider buying a more transparent pre - pro or purchase a higher quality stereo pre, assuming you feel an upgrade is appropriate.
Hope that helps.
