For a final subjective statement to the SQ of the onboard I/V stage, i would like to give it a bit more time to burn in.

All parts are complete new, including the TDA1541A. What i can say now is, that the sound is similar to the DDNF I/V stage.

Look's good

Question: 2 DAC = 2 onbard I/V with output coupled and

the same values???

Hi Antonio,

if you would like to use 2 DAC modules with the onboard I/V stage,
you must build 2* the I/V stage with one I/V resistor and halve the value to 250R to get 2Vpp output voltage.

Are boards for the Tube-I-zator still available and will they work with the v3 boards? Thanks

Perhaps not that dynamical, but keep in mind you don't need any additional parts or modules.

If space and more investment is not the problem, i would go with the DDNF or Tube-I-zator I/V stage.

In my rig the tubes stays with a different tube rectifier.

Interesting conclusion oliver... Have you put this forward to ecdesigns yet? Technically speaking, the onboard iv stage is more elegant (by routing currents back into +5v).

But if it doesnt sound as good... Well... I'd go for ddnf anyway.

I like the onboard iv the best for practical reasons, and a smaller pcb to!
