The Ultimate Line Preamplifier, Part 5


The fully differential ultimate line stage with all silver transformers is more popular than I ever expected, despite the high cost due to the many silver transformers. Here is another one just finished:

Two more are in the planning and one of those will finally remain in my own system. 

This one uses the same color combination as the differential D3a phono with which it will be used.

The sound impressions are still the same as from the last one. So I won't repeat that. You can read about the sound in part 4.

Before the owner of this line stage picked it up I had the chance to use it together with the recently finished ultimate, all silver EC8020 phono.

I'll write about that in the  next post about this phono stage. Stay tuned!

Best regards



  1. super nice....! Glad the design is a success.

    BTW -- where are the power supply capacitors?

    1. Thanks!
      The PSU caps are inside the PSU chassis. On top are two filament transformers, the B+ transformer and one of the B+ chokes.
      In the signal chassis there is no capacitor at all
