Hi JP!
I’m probably going for:
Dac End:
DAC End - the AD1865N-K with single ended vacuum output stage

Or....

Dac End 2 (without the expensive LL1660AM trafo’s):
DAC End 2 - the AD1865N-K with single ended vacuum output stage


TJ,
The Retro Dac looks pretty cool also.
Which version DE did you try?

Mine was the normal Dac End. I should also mention though that in mine we use the transformers as interstage coupling transformers and then its a simple capacitor output from the tubes.

In this way the transformer acts as a filter of sorts.

We use 417as on the output to keep the output impedance as low as possible.
