This is the problem you have when you take a chance and just guess on a new component. Preamps are way too important to not get right. Given that, you probably will get lucky. BAT is very well made and should work with a large variety of products. The only advice I can give beyond that, is that if you are not happy, you will not make the situation any better with cables. You may think you will, and when you ask, you will get an endless list of recommendations on what cable you should buy to fix the problem. In the end, though, it just wont work.
Also, it is not clear if you already have the Parasound amp or just plan to buy one. If you don't already have an amp, I would strongly urge you to consider a BAT amp to match the preamp. Doing so can eliminate a lot of problems.
