My answers by topic:
1- I've been listening and improving my system for a considerably long time and when I refer to "better" sound, I don't mean coloured, but more accurate. By that I mean issues that I believe cannot be coloured or "invented" by any part of the system, they dont exist from the beginning, the source.
Let me explain better. As my system got better in accuracy (it is PRETTY revealing today), it evolved in aspects I'm sure cannot be done colouring or masking the sound, only improving the information the system is amplifing:
- Better tone: more real and analog sound, less edgy, LESS SIBILANCE. You know what I mean: LESS DIGITAL SOUND.
For instance: in the song "Still falling for you” from Ellie Goulding from Bridget Jones’s baby Soundtrack, wich is at the end of the movie and its NOT an audiophile song, in the chorus "on Tidal" you can EASILY detect sibilance on the F and S letter of the words Ellie sings and, on Netflix, the sibilance is almost totally gone. Its so obvious, that I guess you dont need trained ears or a hi end system to hear it.
Well, that sibilance makes the system sound "digital", affecting the tone and worsening the realism of the instruments and voices. That issue CANNOT be coloured, it is just poor quality digital processing.
- Less ground noise, cleaner soundstage, better separation and layering.
- Deeper and wider soundstage.
With the same song, and others, on some Netflix movies, my speakers TRULY disappear. I mean, the image with Tidal and the other sources is GREAT, but on Netflix its like Im inside de stage, its incredible.
I've been listening to my system for a long time and I've got used to how it images the sound, even with the best recordings on Tidal. For me, not even those recordings image as well as most songs on Netflix. I still cannot believe it!! The sound on Netflix has an easiness and flows beautifully. Another issue that I believe cannot be done "colouring" or with an EQ.
- Dinamics and bass impact. I dont mean only stronger bass, but deeper, profund bass, with out changing anything else on the system.
2- I stream Netflix with my Tv is a 65" LG 4k and it's connected to Internet with the same WiFi Router as my Notebook (wich streams Tidal), BUT the computer is connected to the Router via a Gigabit Cisco Switch and a couple of CAT9 Ethernet cables, NOT WiFi.
If I stream Tidal with the computer via WiFi the sound is worse than Ethernet with the Switch. It is easily detectable and AGAIN, its NOT something you can mask with EQ or colouring the sound. The computer (at least mine) works better with Ethernet, it sounds better. Not a huge change, but noticeable.
So the Tv, using a worse digital signal than the Computer, sounds better.
Just to mention, I've used some time Dirac Room Correction. I liked it first and it makes a BIG difference in sound, but then I found the sound with Dirac flat, lean and boring, so I stopped using it. The test I've made were WITH OUT Dirac.
3- The TV is connected to my DAC with a cheap 3m Toslink (optical) cable and my system (for movies and music) is stereo, not multichannel as my main goal is music.
@ elliottbnewcombjr Thank you for the advice. I will try it, but I dont know if the browser app on the Tv will be able to stream Tidal. We'll see.
@ classdstreamer The Jitterbug helped a LITTLE bit, maybe eliminating some harshness on the sound, but its so little that Im not 100% sure.
On the other hand, the W4S USB Reclocker (RUR) does indeed improved the sound. Its NOT a big change, but noticeable, mostly on dynamics, tone and realism of the music. I guess another USB conditioners must produce similar results, but for me even the whole USB chain (RUR + LPS + Gustard U16) is not enough to reach the sound quality I hear from Netflix.
By the way, the quality sound is MUCH worse if I connect the computer directly to the USB input of the DAC, avoiding the RUR + LPS + Gustard U16 chain.
The only answer for me is that the computer is providing a truly awful USB signal that cannot, or is too difficult, to correct.
PS: for the guys that BITS ARE BITS, I can asure you that its not that simple. Time domain is critical in audio and if a piece of gear on the chain introduces jitter, noise, whatever, it will affect the sound BIG time.
Just to mention: I also like photography and I've had great pieces of gear, mostly expensive lenses, but I sold them all and kept only what I need. What I mean is that I don't buy or keep pieces of gear only for aesthetics reasons. I've had also tube gear (300B and EL34 integrateds), wich really looked BEATIFUL, but I sold them because they didnt sound as good what I have now.
