Your thoughts on best audiophile speakers in $10,000 neighborhood?
burtlake +1. I too had a great experience with Audio Dimensions and Harry. I had a SP-06B and had it for at least 15 years. Way ahead of its time in sound quality. It sold so fast it was surprising. I enjoy my SF Olympica Nova 3s and for no larger... 
Connection options from Node to Denafrips Iris to Pontus
The U1 I have was considerably improved with the Sbooster power supply. The Node worked well with a USB out into the Iris and then out into the Pontus via I2S. The sound was exceptional. However, once you have the Iris, it ONLY has a USB input.

Costliest Brainfart
I would say think of these unfortunate mishaps as educational. Education always comes at a cost.
