If you’re not getting any dropouts, there’s no need to buy anything.
As long as the DAC is getting the data intact (whether wired or wireless), there’s no improvement to be made. This is the beauty of digital data.
What can I do between the wall and my streamer/DAC?
I have AT&T fiberoptic internet and the AT&T supplied router. I then have generic ethernet cable to the music room in the basement to the back of my Lumin T2. Is the anything I can do to make this a better sounding situation? I feel it sound very good as is, just wondering if I am leaving some goodness on the table with this set-up, Thanks, Allen.
