The MOSFET-based Yamaha integrateds (A-S1200, 2200 etc) go a long way in emulating tube amp sound. More so than any other integrateds I have encountered, including hybrids using tubes on the input stage.
Though listeners I trust assure me that the Croft Phono hybrid integrated sounds very much like tubes.
The Axxess Forté1 is another that gets at least halfway to bridging the gap between tubes and SS.
