My Audio System is pretty much Commission Built where a large proportion is unique and not duplicated.
There was not any Pre-Listening only Pre-Discussion and attempting to align my wants with a EE's thinking to create something close to my concept.
A Pre Amp' is being built currently for myself, under the exact same practice as the above, but on this occasion I have a loan of a version of the SS Section of the design.
A SS Phonostage is also currently being produced for myself. Even though I know the design and have been demo'd it in use on quite a few occasions. The EE Builder is introducing tweaks that they feel I will enjoy more than the standard model. A comparison will be carried to see which model I am to settle with.
