No, Dan. The first thing I swapped out was the 12AX7LPs which are at the first gain stage (V1 & V2 in each channel). The improvement in soundstaging and three dimensional layering was nothing short of spectacular. The swap did not, however, kill the tube rush. Next I swapped out the Sovtek 12AX7WBs for EH 12AX7 gold pins. Perhaps slightly warmer sound, but still no improvement in tube noise. The last tubes to go were the Sovtek 6922s in favor of the Siemens 7308s. Thats where I lowered the noise floor considerably. I can now listen virtually as loud as I dare and tube noise, although still present, is not audible from the listening position and that is at two gain settings higher.
