These are not merely an IC with more conductor material, but two discrete ICs conjoined complete with their independent grounds.
I invite you to see my seminal article at Dagogo.com "Audio Blast: The Schroeder Method of Interconnect Placement, and the thread on the cable forum bearing my name. You will see that it is meeting with growing approval and praise from users. There have been some caveats brought up regarding gear that might not be suitable, including NOS DACs that send the signal from the chip, and it is unknown largely how Class D amps would react, but caution has been advised that some may have oscillations as a result. However, TEO Audio has successfully used the Red Dragon S500 with Schroeder Method.
If you have concerns speak to your equipment manufacturer about it.
Personally, I will not use a single IC again for my own systems, as it is paltry in comparison.
