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

@ 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.

If it’s SIRIUSXM or AMAZON MUSIC, ( I use TIDAL which has a hi-Rez option as well as “ standard” compressed MP3 ...I’m not a S or A subscriber ...) they appesr to be the latter ultra compressed MP3 level formats

if if so then a hi-Rez upgrade in hardware or software is a noble thought but a playback upgrade waste if you are only dealing with a low-level compressed streaming digital format steaming over the air .
In direct non-hi-Rez (320kps) mode digital file playback directly to the car input , the 3.5mm mini-RCA cable upgrade from a “standard” link suffers also a similar fate.

HOWEVER, IF HAVE A LEGITIMATE HIGH RESOLUTION SOURCE FROM STREAMING OR DIGITAL FILE DIRECT PLAYBACK

I have a top WIREWORLD 3.5 mini to mini RCA cable in my hi-Rez playback. It’s a big step up from cheap throw- in phone accessory IFF with the AQ Dragonfly / Onkyo Hi-Rez app ensemble, AND (emphasis added) HI-REZ format input.  The audio playback performance improvement on a hi-Rez source file (TIDAL for streaming, or resident on my iPhone) is not subtle.

my take

Unless you choose to eventually upgrade and adopt a different full high-resolution digital streaming source (a la TIDAL) or a direct hi-Rez recorded digital file sourced and resident on your phone , then stick with the basic cheap setup and accessories.

I also concur with streaming a high resolution signal.
I can hear the difference between XM- Spotify-Tidal, easily.( The latter being the best).

So, today I received the Golden Gate mini-to-mini interconnect cable.  Immediately upon connecting them, they don't sound any better than the el cheapo Griffin cable I've been using.  Actually, it may sound worse at this point, seemingly making vocals sound more "edgy". 

I don't know how much I subscribe to the notion that cables "break in" over time, but I will keep playing them for a while and see if anything changes.  I have until March 29 to return them.  Unless the AQ cables start sounding noticeably better than the el cheapo cables, I'll return them.
