Thanks for the kind words. Could you elaborate, what you mean by the low-loss path after the last choke ? I use what I call a filament bias arrangement. The bias is provided by the filament current, which is drawn through a (low value) cathode resistor. See attached schematic.

It was more like a semi-public event or private party. We call it "Schall & Rauch" ("Sound & Smoke"). It was the second installment of such an event in Munich. The main purpuse is to give people the chance to listen to some of the systems of the "Munich Triode Mafia" at their homes. So we organized small groups of 4-5 people who visited the Munich guys. In addition we had a central location called the "Vinyl Mafia Central" or VMC, where we set up a system and where we did turntable comparisons. We had 13 or 14 different turntables, vintage classics like various Garrads, studio EMTs and modern legends like the Scheu or Morsiani. All turntables where listened to using the same (externally mounted) arm and the same cartridge. I'm sure some reports will appear on the web soon, with photos.
Best regards
Thomas
