I have been storing a pair of Beolab 8000 speakers for quite a while under my staircase, My sumption was that I would only able to use them with B&O components, but only recently i realized that they have a line setting to use with non B&O systems. I now have them hooked up with a Yamaha 590 suround receiver which has pre out and it sounds actually surprisingly well, but I do want to get a decent preamp that is resonably priced to use with the beolabs. Any suggestions wil be appreciated.
