Quality line-level / RCA splitters???

[Timster 7]

Hi, Picked up a nice studio power amp. Probelm is - it is not integrated, so I have a (1)Right Channel in and (1) Left channel in. (RCA's) It is for my office and I am running one pair of B&W 601's. I have a CD player, but I wanted to run my PC audio as well. My sound card has RCA's out. I would never have any reason to run both at the same time (obviously since it is only one set of speakers!). Can anyone direct me as to 1) Should I even run a spitter at line level. and 2) How much quality will I loose and 3) any brand reccomendations that will not break the bank???

1) Yes.

2) You shouldn't lose any quality.

3) Any basic splitter like this one from Radio Shack will do: http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&category%5Fname=CTLG%5F003%5F010%5F011%5F000&product%5Fid=15%2D1982
