Ethernet connection for best sound quality

toro3    I  have an OPPO UDP-205. Let me start from the beginning,,,,

2018 bought the 205 streamed through desktop (fans and all.)  Tidal I believe it was called premium at that time Via Cardas clear network cat 7 cable. from wall to computer then from computer soundcard Soundblaster X-fi Xtreme to 205 via Cardas Parsec coax Great selection of tracks from my favorite bands that weren't available from lp's cd's youtube. live selections so forth. I thought it sounded fine, I still do. But if I can get a higher quality sound I'll go for it.,I was just hoping for a direct connection from modem to the 205.via Ethernet cable. I plan on using a 1TB SSD via Cardas clear high speed internet usb cable once I have a collection.

Thanx for ALL the input.

Since the last time I used Tidal it was 2018. I’ve since moved. The only DSL line is in the living room so I’ll have to connect a 25ft. cat 6 ethernet cable from the tv router to a second router Asus RT-AC3100 in my listening room.

Then a dedicated ethernet connections to the desktop computer and another to the Oppo-205.

Now I’ve just listened to the cd’s I burned back then.

DSL to desktop computer to

Oppo to

Tascam cd-rw900mkII cd burner.

As far as SQ is concerned from the Cd’s the only complaint I have are the dynamics.

The music I download now is from youtube stored on a SSD lacks clarity.

So until I save up for a streamer, This will have to do in the meantime.

I would like to use a coaxial cable between the streamer and the Oppo.

In My minds eye I’m hoping for both an improvement of clarity and dynamics.Akin to a phono amp which amps the volume a bit more than without, especially with a MC cartridge. The streamer will be the phono amp. The Oppo is capable of wide dynamics.which will be the pre amp.

The streamer will be dedicated to my hifi only. Strictly for music.in one room not for the whole house.

Thanx for the info.

If USB has a better SQ then I will.

Concerning the ifi LAN silencer.

The Chain; DSL- to modem- to router- to streamer- to DAC.

In the chain it should be placed? I figure befroe the streamer, I cannot see any sense in cleaning the bits that arrive to my computer.

Working backwards,

before the streamer?

before the router?

before the modem?
