I would definitely give the SiC diodes a try. The impact of any differences
in noise will depend on the circuit and application.
I was only familiar with the low voltage drop (0.2V) Si Schottky diodes.
I'd like to work out a few nice low impedance ( < < 10 ohms) devices myself.
For something like a 5842 or 6C45Pi output stage even 10 ohms in the cathode
adds a lot to the effective plate resistance.

Here's something to try if you want about 2.5 volts - a small MOSFET, like this 2N7000, with gate connected to drain. Dynamic resistance is around 10 ohms (similar to an LED)and voltage drop is Vth.

You may use tube diodes. After you finish with SS marvels, try some old tubes :)
That sequence brought me great joy :)
Happy Ears!
