@stereodynamics   Ron: I would ask Tektron Italy directly.

@stereodynamics   Are you all set on the bias settings?

I'm curious about which tubes you prefer with your Tektron amp and your overall thoughts of the unit?

It has been a pleasure and an education participating in this thread. Learned a bunch that helped me appreciate not only my Nenuphars but this hobby.

I’ve moved on from the Nenuphars to the Boressen Z2 Cryo edition speakers. A leap forward in everything I love about the Nens (and more), but at a cost of $10K plus. I’ll be posting a review of the Z2’s as a separate thread in the next month or so.

A pampered pair of white Nenuphar V1s will be going up on ’Gon shortly.
