Who has a separate DVDA and SACD player?

I currently have an SACD player that I am very happy with. It also serves as my DVD player. However, there is becoming enough titles that I desire being released on the DVDA format that I am interested in picking up a DVDA player at some point in the future. I am not interested in a universal player (for various reasons) and would prefer to have two separate players. My main question is for those of you out there who do have the 2 separate formats and don't have a universal player, what type of preamp are you using? It seems that all of the preamps out there only have 1 set of 5.1 inputs. Since I don't want to rewire each time I want to hear a different player I need to find a pre with 2 5.1 inputs. How are you guys accomplishing this? - Tony
