Audioquest Golden Gate or Big Sur mini-to-mini cable for my car use?

I'm currently using a cable that might be considered the cheapest option -- a Griffin 1 meter cable.  It doesn't sound bad, but you never know if a higher quality cable will make a difference until you try it.  So, I was going to try one of the AQ cables.

I concur with Nutella, when you count road/engine noise, I doubt you will notice much difference unless you have really sensitive hearing.
Also, consider that all your cables and equipment will be subjected to heat and cold, which will also affect performance.

Thanks, I went with the cheaper Golden Gate, and I had an Amazon gift card my kids had given me, so it didn't cost me much.

Good call

the mini RCA to mini RCa cable link is not the Raod to OZ most  important link for headphone or car audio.  Instead, an investment in a quality build mini- DAC/headphone amp, an APPLE  camera lightning to USB converter (if required) , AND a high-resolution player app to go along with a mini-RCA cable is a better upgrade path. The AQ mini-RCA cable performance difference between your models in a direct bake-off is negligibleto nil.

why?

(1) the “standard” internal phone DAC is a cheap comparative  low level part and low-level audio performer available to be bypassed with an external mini- mini-DAC/headphone amp capable of hi-Rez digital file playback

(2) the “standard” internal phone player app is likewise a low level minimal quality and comparatively poor performer lacking hi-Rez output, that can be supported,anted with a new player app capable of hi-Rez playback.

- The external USB MINI- DAC (and Apple camera Lightening to USB converter if required for IOS)

(b) TEAC HR AUDIO PLAYER ...ibid...

@ akg_ca
Thanks, very interesting.  So, in addition to the analog signal that comes out of my Galaxy S8 cell phone, is there also a digital signal?  BTW, the content that I'm playing on my phone is SiriusXM and Amazon Music.
