Is there any Sonic/Sound difference between RCA cable or 3.5mm or 6.3mm cables ??

As per topic, I am wonder if using RCA plugs is "better" than using 3.5mm plugs.
Since the RCA cables is dual mono, is it said to be "cleaner" than 3.5mm cables, which is single stereo ?? Since it seperates the channel cleanly... ?

Another question would be.
In the past, I always had this mindset that 6.3mm plugs are for headphone with high impedance, is it wrong to say that ?
And, other than the size, does using 3.5mm plug or 6.3mm plugs differs in terms of sonic performance ??

Thanks for opinion and answers, greatly apperciate for those who helped out

These few questions are always on my mind, and I am going to graduate from making IC/lod and start making headphone cables and docking stations with caps and rca out, so I am wonder if they make a difference.

Just sharing, my docking station would be having dock input, 3.5mm input, 3.5mm output, rca output, mini usb input/output. So I am also wondering if I just have both rca and 3.5mm input. My newest amp, the Audio track imAmp has rca and 3.5mm input, but I don't have the cables to try out the difference for now.

the 3.5mm will bound to have crosstalk.
so will the 6.3mm.

the 3 path are so close together on the jack/plug that it cannot be avoided.

RCA will be better of course

Lol, hi reaper.

So between the choice of 3.5mm and 6.3mm, which will you choose for recabling job ?
Or it doesn't matter, and you will just use 3.5mm for iem/earbud, and 6.3mm for headphone ?

Oh.. so the best Interconnect would be rca to rca right ?
Thanks

The only answer is simply depending on your need. There's no point in recabling your headphones in 6.3mm when you only have 3.5mm jack on your gears. The same with the interconnects.

agree with lil' knight, you use which ever is most suitable for your recabling job.

and i don't think there is any significant difference between the 3.5 and 6.3mm in sonic difference.

Haha, I thought of these few on my own.
1) 6.3mm - preferable for headphone, as the drivers are bigger, hence more power is needed to drive it, hence would need thicker wires, and for it to be able to be put into the plugs, the hole of the plug got to be big, and 6.3mm's plug is usually bigger than the 3.5mm plugs. Moreover, it is more sturdy and higher build quality theorically since there is more space for their construction.
2) 3.5mm - preferable for portable as it is small, to fit into portable amps.

Anyway, the amp that I am using is the Audiotrack imAmp, which has 3.5mm jack AND 6.3mm jack, so it doesn't matter haha.
but I guess I will stick to the theory I made above

Thanks guys

First time I heard this 'theory'.
