I have a tube amp 200wpc.
I am looking for a deeper wider soundstage. Looking for a pre which I hope will help in this area..
I listen to a lot of classical which tubes are wonderful for but I'm looking for a deeper more layered soundstage and for the classic rock and jazz which I also listen to I'm looking for more dynamics and slam which I lost a bit of when I went from a SS amp to tubes.
Hope this helps.
