"Gold Band" is merely the common name for the species, not a variety name. Regarding that link, I suppose it's just my opinion, but anyone who calls a species lily (like Lilium auratum) a hybrid is suspect from the start. By definition, species are not and cannot be hybrids. I take exception to several of the author's recommendations.
5.5-6.5 soil pH is fine. The closer to 5.5 the better, because it will reduce the number of potential problems you may encounter. The simplest (and in my opinion the most advantageous) thing you can do is keep the bulb out of excess moisture with roots in reach of constant moisture. It's not the easiest thing to accomplish in most gardens. I've grown L. auratum for ten years. I have clay based soils, and plants bloom nicely but come and go in moister soils; my oldest ones grow in a quite dry regime, but only bloom one to four flowers annually.
