Id say try some other power cables. Following that or previous to it Id say just roll some more tubes. The dodds are a bit forward sounding, geographically speaking, that is.
Playing with some other footer or amp stands for them may help out too or under the preamp and/or source itself.
My speakers sit off the short wall in my approz. 14 x 20 x 8.3 room
My sound stage extends beyond the wall behind the speakers, past the side walls and encroaches upon the LP, with the sound resting near to the sides of my chair.
As mapman said too, this is with well done CDs.
The Shunyata Taipa Helix Alphas add width and height while maintaining cohesion
the Elrod adds depth, and as well as the Voodoo Tesla II.
Personally for pure spaciousness without making wholesale changes Id try some power cables first
They seem to set the stage for other system changes by allowing the sound field to grow vertically & laterally, and/or to deepen providing more rear of stage info and ambient retrieval
. And I say this is true regardless the components they are attached to as Ive had these cables for some time now with different components
The Python A & later still, the Python helix A will, all by itself, gain you a quite expansive SS while still remaining coherent and intuitve
the helix version gives more refinement to the bandwidth and far, far greater rear of stage (depth) info. Place it on your source or as supply to the Dodds. The Elrod Sig III is best only supplying the amps or the power cond itself as it likes to pass more current better.
The sound Anchor stands I got for my Dodds just added focus or localization of the imaging, as did the tube rings I put on the 3 little tubes.
You put an Elrod Sig III on the supply to the amps and your stage will gain a lot of air right there. Add a Python A or Helix A and youll gain still more landscape
walls, not withstanding.
If you can get Telefunken tubes in your pre theyll gain you goodly amounts of that spacious effect you seek as well.
Good luck.
