Trying different Pre's is a perfect start. I assume since its nearfield that its a fairly small room. If so, room treatments are critical. IMO, cabling becomes even more important in the nearfield too. Furthermore, I agree with you, I dont think the PS Audio makes a synergistic match with Bryston and VS.
Finally, after trying the new Pre if it is still not involving. Try a few room treatments (towels, blankets, and pillows make for an interesting experiment)and maybe a cable change or two. I liked Harmonic Tech with Bryston (Truthlinks are inexpensive and very available used)Surely by this point you will have found some characteristic that you like and begin to build upon them. In the end it may be the Bryston. But I suggest small steps building up towards what you want. Dont toss the baby out with the bath water.
You could try Power conditioning, or removing it, as an experiments well. Oh yes and definitely tweaking the speaker positioning. Thats very important in small rooms.
