a small update, the creator of my DAC will be sending me two items: 1) a TDA1543 DAC that shares many design elements with his TDA1541 model I wrote about in post #161 2) a hybrid headphone amplifier based on the 6N6P triode and a germanium transistor output stage both of these items will be offered on loaner program here once I receive them, if there are interested participants. I estimate around 2 months for assembly and delivery from Ukraine, hopefully shorter, maybe longer. I have received a few PMs about the abbasaudio equipment and I think 2 people have already purchased a DAC from him. hopefully they will share their thoughts once ready. I have no commercial affiliation, I am just glad to open more doors to good sound for people.
