Ventus are driven by legato bal out for my Grado (32 ohm). I'm looking for a power stage to connect at legato unbal out. My target is to listen jazz or classic music with B&W 805. Any suggestions??

Ventus is about 2-5K inp impedance, sympatico about 100K. Surely legato can drive them but what about interactions (if any)? I've an order shipping next Feb 27th. How can I add a sympatico kit?

That is a superb suggestion. I'm not sure I understand this branching, but I very interested as I have all the modules to try it! Do you mean using 4 pcs of Ventus as line-stages between the bal out of Legato and the bal in of Sympatico?

The Sympatico inputs would be wired in parallel with the Ventus inputs.

Could both be powered, connected and used contemporarily yielding (per channel) one balanced an 2 x SE outputs? Or is this to much for the poor Legato. The modules stacks nicely - just a shame that one has to take apart the pyramid to access one of the Ventus trimpots :-) NicMac attached the following image(s): TheTpaPyramid.jpg (31kb) downloaded 156 time(s).

It will work quite well actually.
