I don't know if they are the only ones doing it but I have used the Jolida and like it very much. The tubes are only on the L/R output (do you really need it for mulit channel?). It gives you pretty versitile connectivity (XLR stereo out) and buttons on the front pannel to control it (many manufacturers are not doing this now). the remote sucks but most peolpe have a universal these days anyhow.
