Could anyone suggest one? Do they exist?

Of course, Balanced Audio Technology (BAT) comes to mind as well as the Aesthetix (sp) Callisto. Also, any of a number of tube pre using transformer-coupled outputs usually also offer balanced outs, such as Audio Note and possibly the soon to be released WAVAC "reference" pre-amp. I'm sure there are others as well.
The LS16 Audio Research is the same guts as the LS25, only it's got less inputs....nothing more.(even according to the AR technicians. And,the LS16 is much cheaper used.(upgraded tubes are mandatory for better sound)
What price range are you after?
