If anyone lives in the Bay Area, I would love to compare my Elyse DAC to your Big 7 or Golden Gate. Not to see which is "better", but how they sound and integrate in different systems. My hats off to both the digital and analog designers of each company. But I have to add, I will never buy a component that has to be serviced outside the USA. If something needs to be serviced on my Concert Fidelity pre, I have to send back to Japan. When I had a Chapter Audio amp form England, it was a pain in the arse to send it back. And even for repair, US customs tried to tax me.
I'd bring by my big 7 to listen for a few hours some day. I'm here in SF
