I just turned it on yesterday literally for two hours as we have 4 days of vacation here so there was no time to play much nor listen but as I said i wanted to check if peace on this planet is possible so I combined USSR triodes (6n1p) and Russian made KT170 with US made RCA 5u4g top getter recti (which i love) all blended, of course, by Polish DAC and to my surprise they work beuatifully together.What rectifier and which triodes are you using. I find the Thomson CSA 5687 to sound best in my system. The Kt170 plus the Tak274B created by far the best dynamics
Based on this learning there is still some hope for all of us
