Just curious if anybody has heard this amp with say Sus/Phi TC / HE6 out of the ribbon output and compared with say something like Niimbus, V550, Volot, Soloist 3GT, Oor+hypsos ?

It’s cool this would drive the Mysphere and SR1A but not sure that it’s at the same level to drive the other planars.

A used one came up for sale around $2800 and I’m sure is negotiable a bit… The amps that are more of a swiss army knife seem to be good at everything not great at anything (e.g. Audiovalve Solaris).
