@larryi Cube Audio primarily pairs their speakers with Tekron 2a3 SET tube amps for shows and demos. Sometimes the US Distributor uses First Watt SIT amplifiers at shows. Very unique solid state amplifiers designed by Nelson Pass that behave electrically and sonically like SET tube amps. The SIT-1 and SIT-2 have an output impedance of 4 ohms and a damping factor of 2 while the SIT-3 has a less ideal .25 ohm/30 DF rating. This review explains in all thoroughly: https://www.6moons.com/audioreviews2/cubeaudio2/6.html

Cube Audio has explained in detail about their rationale for good amplifier-driver matching. No doubt that the speaker owners can choose what ever amplifier they want to.  Cube Audio is only offering informed guidance.

I noticed a comment on the previous page regarding Refined Audio, so I just checked.  They continue to import and represent Cube Audio.

In fact, in case someone is interested: a Nenuphar BASiS is listed at a healthy discount  😊  here >>>>

David,

I am surprised that the Jazzon speakers do not appear on their website.
