Dave, I've used both the Precision A and ICON ic's and both are fantastic performers at the price. The ICON's are definitely worth the difference in price, but the Precision A is really close. I don't want to sound too much like a commercial, but I just can't help it! I've been jumping up & down about PNF ever since I first tried them because they literally trounced everything else I've tried (including my own stuff; and keep in mind that I have a technical background and have even built some designs that are very much like the Anti-Cable ic's...). I have zero affiliation with the company, although I've gotten to know Steve Jain there a bit just through conversation about his product. All I can say is, give 'em a try!
Apologies for taking this thread away from the original questions about the Anti-Cables....
