I completely admit I don't have enough knowledge to explain why the AVVT 32B measure almost no mV when adjusting the hum balance in the Paramount.
Back to the Stereomour and the 2A3 though, I spoke a little soon on the sonic differences between the Sophia Mesh Plate 2A3 vs Sovtek 2A3. I invited a friend over today to listen through my tubes and amps. I started with Stereomour with Sovtek 2A3 driving Omega Hemptone 8 monitors and then switched to the Sophia Mesh Plate 2A3. He was blown away by the differences. Then I played him the same music through the Paramount 1.1 with Sophia Mesh Plate 300B and Tekton Design Seas Pendragon and his brain melted. Point being that he heard a much more definite improvement over the Sovtek 2A3 and Sophia Mesh Plate 2A3 in the Stereomour. So much that his exact words were, "I can't believe all you changed were the tubes!" I do agree that the Sophia Mesh Plate 2A3 tubes give much higher highs with more detail and clarity to the point of delivering more dimensional and airy sound than the Sovtek 2A3. The Sophia Mesh Plate 2A3 are an amazing paring with the Stereomour and do a fantastic job driving even the 95dbn 1W@1M Seas Pendragon to volumes loud enough for the neighbors to hear.
