Well, there are many full-function preamps. It is a common tendency nowadays to make an add-in board with phonocorrector to a line-function preamps. Recently even the full blown tube preamps use the j-fet phono-boards.
Interesting that I would like to see opposite thing that unfortunately no one use. If you look my thread:
The ultimate buffer – light in the end of a tunnel
then you might realize that I do not believe in the absolute transparency of the tube buffers, at least I was not able to witness one. So, I would like to see an attempt of making a full-function preamp with: two stages 70dB phono stages (for instance around the 7788) and a Placette-level SS buffer. It might be very interesting…
