Coaxial vs RCA in audio

[Chris Anderson]

Toss a coin.

Yea good answer from people who
declare that they know about hi fi and have professional knowledge

Luvinthehd gave you the best answer given the circumstances.....You are the one with the cd player and amp (models whom you still refuse to give) not any of us....we can't hear what you are hearing.

You are the one who hears the difference between Coax and RCA, stating that the RCA sounded better. This means you like your cd players DAC better, and that's fine.
Then you want to start a theoretical discussion...what if the amp had the same DAC? What connection would be better ? Well, TOSS A COIN.
They both will sound the same.
Instead of having a revelation based on the facts presented to you, here come the insults. Same crap you pulled on that XLR discussion.

Your style of trolling is very odd.

Cd player and amp refused to give???? I expect answer yes or no left or right you know or you don't I don't have time for stupid reply like toss the king and what the hell is that mean you don't want to help then poop up if you are able to help me out then say so etching useful simple fucking rule
I see this that way
I got my answer from a different forum thanks a lot ,, professionals,,

You seem to be a particular type of belligerent twot.

This is simple.'

An analog RCA cable is designed to have an optimal impedance of 50 ohms. This is NOT resistance. It is not for transferring data, but an analog signal.

Ab RCA digital cable is optimally designed to have an impedance of 75 ohms. Again this is not resistance. It has a maximal data transfer rate of 9.2 Mbps. Having said that within limits and in practice the cables usually appear to work interchangeably.

The next and last point is that if a CD player has digital and analog outputs, if you use the analog right and left RCA outs, then you are getting an analog representation sent down the cable. The DAC in the player does the conversion. If the player is connected to a digital device such as a receiver, then the signal can often be converted back to digital and then back to analog. This creates a double conversion situation..

If on the other hand you connect the digital output from a CD player to a device, you are transferring data in bits. This is data. The receiving device does the conversion and there is only one conversion.

This is all you need to know about this and it is end of story. If you can't understand what I just wrote there is no help for you, and further belligerence will only trash your reputation further.

Ok now is more clear thanks but what about
signal data throughput which cable will carry more information I know already the coax can deliver max 24 bits up to 192khz but what about RCA ???is a analog cable with different singal he can deliver high resolution like that?

Using an 'analog' cable doesn't matter. It might over a longer distance, but those cables aren't limited to the audible frequency range.

of course I understand and thank you very much, as the saying goes, hit the table and the scissors will respond, it paid off to be a two-year-old thanks again

Can someone explain to me which of the cables will reproduce a better quality audio sound QUED PERFORMANCE COAXIAL VS QED Performance Audio 40i RCA or standard coaxial vs RCA I did some listening tests on the CD player and in my opinion RCA sounds better has a more detailed sound texture where coaxial is flatter these are small differences but however audible BUT is RCA really a better or worse cable for listening to audio what is your specialist opinion???? length of both cables 1 meter I would like to hear from someone about some measurements
maximum bandwidth kHz, etc

also here is a suggestion ridingpick.com

The choice between cables for better audio quality, such as QUED Performance Coaxial vs. QED Performance Audio 40i RCA or standard coaxial vs. RCA, can be subjective. Some people may perceive a difference in sound texture, but there is no definitive evidence or consensus. Objective measurements can provide insights, but the impact of cables on sound quality is often subtle. Ultimately, personal preference and listening tests should guide your decision.

 

[BMXTRIX]

....let's say both have exactly the same DAC

Use digital on either Toslink or Coaxial cable. They will carry the exact same sound between devices. But, by avoiding using analog cables, you won't have any chance really to pick up interference which can occur over analog cabling. Fiber being slightly more capable, but kind of like HDMI vs. RGB, you always go with a digital solution over a analog one for best results for less money.

optical fiber is the worst cable for audio because its maximum performance is 96Khz where coaxial mange 192 kHz or more XLR or RCA or COAXIAL is the best for the audio quality COAXIAL will be good if DAC in cd player and in amp will be the same but if DAC is much better in cd player then XLR or RCA will show best performance

That is false as TOSLINK SPDIF can carry 24 bits/192 kHz stereo and that is same as COAXIAL SPDIF. As this is digital out on your CD player a 24 bits/96 kHz limit means nothing as the source is 16 bits/44.1 kHz sample rate.

In some cases TOSLINK can help solve ground loop issues.

 

[Trebdp83]

Toslink(Optical) limits of 24/96 are imposed by some hardware, not by the cable itself.

It's true
source is 16 bits/44.1 kHz sample rate BUT cd with 24bits 192Khs DAC will upscale the source right?

There are no CDs at 24/192 and any upsampling will not bring any audible improvements.

A real audible improvement is to leave stereo and go multichannel instead.

Chip DAC in cd is 24 bit 192 kHz and if cd player is optional with SACD then his DAC is 32 bit 192 kHz or more the same is with pictures resolution 1080 p picture will look better and a bit sharper on 4K TV instead full hd TV with the same resolution

If I am wrong then bring some knowledge proof explain me meaby my thinking and understanding is wrong but logic send any cd disc is recorded in 16 bit 44,1 kHz so why cd player manufacturer will put chip dac with max resolution 24 bit 192 kHz for example standart normal cd player
Yamaha CD - S700

Normal discontinued cd player? I'd imagine that feature is for the usb port rather than for cds in any case.

@lovinthehd @highfigh
I just read this thread for the first time from start to finish. Its a fairly straightforward inquiry to begin with and the facts were laid out pretty well by the AH brethren. What I perceive here is the OP in this situation isn't interested in learning something but posts here merely to argue and to postulate and hear himself speak. (can you hear yourself speak in forum posts? somebody should write a post on that).

Kudos to the AH brethren for keeping things civil even when the OP resorts to namecalling and gradeschool insults. I don't enjoy that point of view and I'm glad the forum folks here just "stuck to the facts" for the most part.

The Yamaha is NOT an SACD player.....all output from the cd player part will be 16/44.1.
Where did you get the notion that output would be "upscaled" to the full capabilities of the chip?
Yamaha just used the same 8 dollar chip in various players.
Even if output was "upscaled", that would accomplish absolutely nothing...you can't add what isn't there.

You have an extremely overpriced, badly reviewed standard cd player...that's it. Game Over.
No magic cable, RCA-COAX-OPTICAL is going to make the player any more than it is.
