Lol No, I'm not in sales, and I could care less if you won't be as enthusiastic as I am with the Sablon cable since I listen to hours of music daily and I am relishing on the improvements I'm hearing. I haven't really heard any negatives from it compared to my previous USB cables (Audioquest Cinnamon, Kimber USB-AG), and there's no way I'm going back to those other cables, not when I'm hearing such sonic bliss.
And no, it's not just digital signal, if you've read about digital time domain and cable geometry and how they affect USB transport. Unlike sending data to a hard drive where there is error correction (the destination can detect in data packet and error and request the source for correction) that doesn't happen with USB audio. Go read up on what Gordon Rankin, the guy who introduced asynchronous USB transfer to the audio world, says about how USB is not just digital signals. He has listened to thousands of USB cables, he knows the difference:

And yes, my friend and I did pure blind tests on 6 USB cables at The SourceAV from a DAP to an Innuos Phoenix USB Reclocker (which we also take out of the chain during the test) to a Chord DAVE to an Audeze LCD-4z, and we can definitely hear the different sonic signatures between each cables. All 3 of us can, and only two cables we'd get mixed up as being too close to each other.
As for anyone coming over, I have had a few people over, but only once they've shown they've taken the test recently, wear mask the entire time, and keep social distance even in the room. I'm tested twice a week on my job, so I'm very aware of having a strict COVID protocol. But you're right, it's still wishful thinking right now. Oh well, a lot more listening enjoyment for myself, lol.
