“I’ve yet to find a dealers/salesperson who doesn’t let their biases get in the way of getting great advice”

I know it’s a rarity but they do exists. I have been very fortunate to work with few dealers that are audio enthusiast at heart. They are driven by their passion to help others in putting together great sounding systems.
Back to your query, Is AES better than USB? The answer lies within the implementation of these protocols between the two components, your DAC and streamer. IME, N20 implementation on all of its available outputs is simply stellar and uncompromising. And I expect the same from your Gryphon DAC. What you end up preferring is squarely depends on the quality of USB or AES cables. YES, the cable between the two components is going to matter a lot. I have extensively compared the USB & AES between my components and they both sounded stellar with N20 as a source.
My advice to you, don’t buy a component that limits your options. Why spend top dollars and limit yourself to AES and 24bit/192kHz file resolution (MU1) or K50, that may sound better with AES but not USB. At the end of the day, listen and access what’s sounds best in your system.
As far cabling goes, sky is the limit. Shunyata, Harmonix, Acrolink and Sablon gets my vote for AES. For USB, Network Acoustics USB III, TCHERNOV, Kimber Hybrid are the among best I’ve heard.
Here is another important consideration that doesn’t get mentioned here. Aurender is been at their game longer than anyone else. They offer seamless integration (via Conductor app) with some of the top DAC’s. This integration includes Master Clock sync and advanced Network like RAVENNA. Also eliminates the need for AES, SPDIF or USB cabling. MSB and Merging are two I know of, I am sure there are more.
