Thanks David. You make some great points which I understand completely and will take to heart. My system seems to be dialed in for this particular speaker with the possible exception of the amp. I am waiting on the builder to get back to me on some questions. I know it is a zero feedback design, however I am not 100% sure about the damping and output impedance specs.

As far as Srajan’s review, I must say I find his reviews hard to read and confess I did not read it closely. His style just grates at my patience and mind. Not my favorite reviewer, but understand how others, like yourself, enjoy him.

I look forward to hearing the Mini Basis model at Axpona. I have visited with Jon at Refined Audio and he shared the ideal amplifier specs for the speaker.
Bill, good I was able to help to a degree. I hear you on Srajan's style...most lean the way of your assessment.

Owning a product he has reviewed, at least for me, has lent itself to much better and higher understanding of his work. 

Minor correction from the earlier post. Page 6 and Page 7 are relevant! Please know I don't want to torture you with a 6moons reading assignment. : )

Page 7 of Srajan Ebaen’s review of the Nenuphar Mini Basis addresses your question head on. (Link a few posts prior)

The cubes are a breakthrough in our modern speaker tech.  Absolutely world-class at affordable pricing.

@grannyring   Are you comfortable sharing? Thanks.
The Bakoon 13R sounds even better when used with the SATRI Link via BNC from the Bakoon DAC, imo. I don’t think Srajan has tried that yet? Other makes of dac can be connected through RCA of course. I’ve been told that the Denafrips Terminator works well with the Bakoon 13R but not tried myself.

Speaker seismic isolation is important as Sven Boenicke and Max Townshend and others, have discovered.
