Ifi ZEN Streamer

Hi Tiki, first of all congratulations on your excellent work.
I recently acquired an Ifi ZEN Streamer and the configuration I have is the following: First the Nas where I have the music stored, all in DSD 128, from there it goes to an Intel NUC fanless where I have the Tunebrowser, I have it as UPnP and enable renderer, from there it goes to the Ifi ZEN streamer then it goes to the DAC and from the DAC to the amplifier. The manipulation is by an Ipad mini and Kazoode Linn.
My question is if this is the best configuration that can be done or if you have to adjust and change some parameters in tunebrowser or positions of the equipment.
The sound is fantastic, but everything can be improved… or not.
I’ll send you a photo
Thank you for your kindness and dedication
