@david_ten Thank you David for the warm welcome!

It is a pleasure to join the company of like-minded audiophiles. A little background on me: I have experimented with Voigt pipes in various forms and interpretations, drivers, rooms, and how they fare with associated electronics for over 20 years. I had the pleasure to spend my audio journey with like-minded friends, in a very strong local DIY community, and an amazing mentor (Stu Ono) who was regarded as a fountain of knowledge by a good number of the US leaders of high end audio industry.

I can say the Cube Audio has truly raised the bar! I have the version 2 of the Fc8, and currently breaking them in my Voigt pipe cabinet (which has been my most successful Voigt pipe). 

Cheers, Janos
