We (i.e. Bottlehead) use the HLMP-6000 which is "standard red," i.e. one of the earliest chemical formulations. It has an unusually low ESR, and at one time was known to be quieter than most others. Runs about 1.55v drop per diode. I suspect that the inefficient formulation produces less ESR, but I have not yet learned enough to defend that notion.
Some people use Schottky diodes, but they will have a very low voltage drop per diode, unless you get the high voltage silicon carbide diodes.
Don't use Zeners - they are much noisier because they operate in reverse-breakdown mode. To reduce that you need a huge bypass cap, in which case one might as well use a resistor and get the DC feedback stabilization.
