You are right Piet, at first I used the psps608 because I did not notice that the artifacts in the eTAP were actually working, which I reported to you, if you remember. But the moment you took care of the artifacts problem and they started functioning, I went over to using the eTap2 and never looked back!
As for the eTap2 hardware project, it's great that you have been so transparent and are allowing everyone to follow your work, comment, and take part in the production process. However, I 'm sure that the vast majority of us Shadows "freaks" are not very technically-minded and are just waiting to see and hear the results!!
