Given the stated reason for the no return policy:
"GR Research is a small, direct-to-customer manufacturer. Each speaker is built and packed individually, and because of the size and shipping costs involved, we are not able to offer a no-questions-asked home trial like large online retailers."
It would seem logical to allow returns if the buyer paid for shipping. Shipping to my location would be $240. So, if I returned them, it would have cost me $480 for the trial. That's not trivial and would prevent most, if not all, non-serious buyers. I know I would only take that risk if I was as sure as I could be that I intended to keep them. After 55 years in this hobby, I have learned that there is no possibility of assessing the fit for any product without in home trial with differences in room, equipment, and subjective preferences. I have had my share of purchasing something with unqualified rave reviews only to find that it wasn't going to work out for me.
I hope GR-Research will consider this.
