noise generator diode is very low so we need at least 45dB of amplification, however 65dB is better. The real diffi-culty is to obtain a reasonable flat ampli-fier response. For this purpose I made an amplifier using INA03184 and INA10386 MMICs, the result is shown in Fig 7 and the total response is given by the noise source diode combined with the

What will be missing is the electronic “signature” caused by standard rectifier diodes. The sound will be easier to listen to and less fatiguing. Diodes that have faster switching with reduced switching noise will be less “visible” in an audio circuit. Indeed some of these diodes are known as “stealth” diodes.
Excess noise in high-current diamond diodes: Applied ...
https://aip.scitation.org/doi/10.1063/5.0083383
1 day ago · We report the results of an investigation of low-frequency excess noise in high-current diamond diodes. It was found that the electronic excess noise of the diamond diodes is dominated by the 1/f and generation-recombination noise, which reveals itself as Lorentzian spectral features (f is the frequency). The generation-recombination bulges are characteristic …

Taking a look at the low-noise benefits of an LPS, you’ll expect to get better sound from an LPS. This doesn’t mean you can’t get great performance from an SMPS. In fact, some manufacturers have found an LPS to be noisier than SMPS. I also reviewed the SOtM sPS-500 (a highly filtered SMPS) which faired very well against the UpTone Audio ...
