Curly maple is a standard veneer, and Jim doesn't charge for dyes. Maple also does reasonably well with the simpler one-stage finish that saves $300 and speeds up the build time. However, "burst" is a problem. All Phil 3 cabinets now come with beveled front edges, whether on the "old" style cabinets (perfectly vertical) or the "new" style (slightly canted back front and rear). That allows the front baffle to be veneered with separate pieces for the flat front and smaller pieces for the bevel. It wouldn't make any sense to do a burst on that cabinet because the whole reason for the burst is to allow veneer on the flat portion fading to a burst on edges that are rounded over. Jim's veneer press can't handle curves, and the burst will cover what would otherwise be raw mdf on the rounded over portion. I think a burst would look weird on a bevel, and it's totally unnecessary. Jim goes to considerable pains to source the finest quality veneer possible, and it's always seemed a waste to me to cover up that beautiful grain with a burst unless there is no alternative other than a satin black baffle. Maybe you have to be a guitar player to appreciate burst.
