I had a significant improvement in my Antelope DAC when I installed Synergistic Research fuses x 2 for the stock fuses. I am sure you will hear a nice improvement with the Aurender.
I also own N10, aftermarket power cords would be one way to go before you try any other tweaks. I have mine plugged with Audience Au24 SE MP power cord with great results.
I have been thinking about Stein Music Super Naturals. IMO, solid wood tends to attenuate a lot of the high-frequencies and provides a warmer, richer natural sound.
I have been using Hi-Fi tuning fuses in my pre-amp and amp with favorable results.
