question about ss or tubes

So right now the sound I'm getting is wonderfully enveloping and fills my little space up with the music.  The music has reasonable amount of depth it images beyond the edges of the speakers and sometimes sound comes from behind me or right next to me. However I know I'm missing some detail and it has me contemplating a phono stage and I'm just wondering would I lose what I have going to solid state in order to get detail or is it possible to keep this spacious floating sort of presentation with something like a Sutherland 20/20 for example. On a side note I'm getting some new power tubes for my amps so I think this should help with my detail but my question is still does solid state do this sort of presentation or is not a ss or tube question at all but a system room synergy thing that causes this.
