Cube-tube Noticed your TX11a. I can second your comments about its sound quality. I have the TX11b. If you have not used the noise reduction on 'marginal' stereo signals please try that. I think this is one of the best noise reduction systems I have heard. Keeps much of the stereo separation but really reduces the noise. I also have the TX11-1 which is the stand alone noise reduction system that can be used with virtually any tuner. Does the same thing as TX11/a/b with same great results.
