Description Of Issue
I am considering getting Roon but have been advised my NAS is not of a high enough spec to support Roon to get best results. I accept this but would still like to trial Roon to see whether to upgrade, or buy the necessary new hardware, to enable it to work properly.

My question is if I trial it on my existing equipment will it work well enough, or at all, for me to make the decision on whether to go for the full Roon.
