Never heard the Weiss. I did move from a Wadia 830 with factory upgrade second power supply to the RWA DAC built into their preamp. I did extensive listening of the Wadia (via IC) and internal DAC (so they both used the same RWA preamp).
What you describe in terms of sound is what RWA offered. Hearing off-the-grid audio is an ear-opening experience. Sold my Wadia and never looked back.
If in doubt, order both and try them in your own system (assuming Weiss has satisfaction guarantee). When I was looking to upgrade my Ayre amplifier that's what I did. Ordered a RWA amp and a First Watt. In my case I paid a 10% restocking fee to return the First Watt, but it was worth it to know what worked for my system and listening tastes.
Good luck with your decision. Kent
