Where should I go from here with my digital front end?

Thank you all for your input. So the rest of my system compromises of: Audio Mirror Tubadour 3, Belles Aria Signature Integrated, Audio Physic Tempo Plus. All power cables by Triode Wire labs. Digital and IC are Wywires Platinum. Silversmith Audio Fidelium speak cables. Puritan 156 power conditioner. Going fiber? Relatively Inexpensive and with Amazon's easy return policy no reason not to try. Just so I understand, I still use my Supra Cat cable to connect from my eero mesh into to 10Gtek converter. From there I connect the optical cable to another 10gtek converter and finally another Cat Cable to my Lumin streamer?

Thanks everyone for responding.

I've decided to try the fiber converter route with power supply from Amazon totaling  $163 all in. No brainer in not giving it a shot especially with amazon's easy return policy.

Should have it by Wednesday. I'll report back

So Wednesday my Amazon delivery arrived. I unpacked the two FMCs, fiber cable, LPS with its two extension cords. Connections were made easily except that the extension cords that amazon bundles with the LPS did not fit the input jacks in the FMC. Bummer. Luckily, the LPS provides one and I happen to have a spare.

I powered up the system and and queued up my list a test songs that I'm very familiar with but due to the amount of times I played them no longer enjoy. I checked my DAC and its white LED  light is lit indicating it is receiving signal from the Lumin. Stting up the fiber was a success. Very easy to do BTW.

Before i pressed play, I did notice an eerie feeling as if something was not right. It was a silence that i could "feel" if that makes any sense.

Anyway, I pressed play on the Stone's " Cant you hear me knocking" and that guitar rift blasts out of my right speaker. Audio Physic speakers have a reputation of " disappearing" but this was different.

This was special . I listen thru the whole song, Enjoying it as if I was hearing it for the 1st time. In a way that was true. Hate to use this cliche but I was hearing deeper into the mix. Hearing things I've never noticed before. Loving it. Track after track of songs that I enjoyed at one time but now were reborn.

I Did not experience any glare or glassy sound that Paulie Walnuts experienced :^)The bass did thin out a bit but in a good way for me.   

If you enjoy detail, look into fiber. I can understand some may find it thin sounding.

No bloom or warmth here.

Honeymoon period? Maybe. I have until January 31st to return
