In my listening tests with all Sim Audio gear I found that the speaker is a bit forward. This speaker used to be on the top of my list but I think one can do nearly as good and MAYBE better for a lot less money. But the speakers are GORGEOUS. I would reccomend if you do buy the speaker to put as much tubes and copper into the system as possible. Conrad Johnson sounds great with the speakers I was told but never heard myself. The pass stuff (aleph) that is I heard is pretty warm, so you may be okay. But for more bss oomph I woudl look at Plinius, Sim Audio, Belles, even Blue Circle. Monitors need the juice. I'm not too familiar witht the pre yu have but like I said throw tubes into the mix
