Hello Rdschicago,
I have written reviews on both Melody and Audio Space amps for hometheaterreview.com. These include 300B, 211 and 845 based designs. They are all outstanding, however my favorite based on overall timbres/tonality and image density are the 300B based amps followed by the 211 and finally the 845 tube designs. Even if you drive a 845 with a 300B tube you still will get the overall all sound of the 845 tube, which I find to be the most solid state sounding of all these tubes.
