Lewis, I'm 90% sure I'm going with the HK 525. I like the bass management features it offers and I think it will make a good pre pro. The only debate I have right now is if I need bass management in my receiver at all. I'm researchign the BM of the 563 right now. If I find that it does an okay job, I will skip on the 525 and pick up the 325 insted.
This is time consuming but I think doign the research is even more fun than buying.
