Very nice.
I'll think I'll just ask you to do pcbs next time.

You just always have to turn it theatrical, don't you.

What's next, a cape ? (you already have the Superhero night goggles)

Puta doesn't sound all that French, imo.

In the spirit of ZM's suggestion I have been doing the following for the last couple of years. I directly tap the output of the DAC. The signal is on two legs, each riding on DC (equal but opposite polarity between the two legs). This is sent to step up transformer (2:1 voltage gain and reflecting 4:1 decreased impedance). The transformer also has the added bonus of stripping off the DC.

This is led to the pot and B1 buffer (of course). You probably want to increase the pot from the recommended 25k to 50k so the load on the source/DAC (reflected through the transformer) is high. You may need to slap a RC LPF as a reconstruction filter (although the transformer itself may provide some filtering)

You can go crazy choosing a transformer. My inexpensive solutions (in the USA) are Edcor WSM series (about $10-15) or Cinemag (15 series for about $60 or a bifilar for about half that). Jensen has a series 11 model that should also be a candidate but at a higher cost.

Buffers and transformers are fun to play with (as ZM has reminded us).

Let's face it, everyone at this forum is a Prisoner of ZM-Da.

(a Rustbuffer ! Lordie knows what next)

speaking of DACs , I used xformer for differential I/V , with loading (linearisation) strictly on secondary side ;in fact , several db of missing gain was made with discrete SUSY stage , so input impedance was set as of DAC/xformer freq. linearisation loading
