Its said alot that using soft recovery diodes in the low current rectification is much better than using a generic rectifier diodes.
Im thinking of using one above for my preamp any suggestions?

My DAC is using some NTE571, which are Phillips parts, can't recall which P/N though.
They are sold as soft recovery, 1000V, 3A, and have made a nice difference.
Am also using a CRC snubber as well.
Well worth the minimal funds spent!

I didn't swap standard diodes out in that instance, built a new design straight up with schottkys.
I see no need for fast rectifiers in 50-60 Hz apps. most in audio mistakenly use them because the word 'fast' makes them somehow better. I reckon this practice came the chip amp gurus and now we are here. BTW Those fast power diodes were developed for SMPS tech and then they came out with controlled recovery for the solutions to the EMI problems. what's the problem with using these http://www.mouser.com/ProductDetail...=sGAEpiMZZMvplms98TlKY6I1zmttAFjhvFcnfwhTKR0=

Any Diode of rated current voltage and current will do. Sound difference originate between the ears of the listener😉
The significance of reverse recovery effect is more of a concern when the diode current pulse peak level, and load current level becomes substantial.
The only valve circuits that generate current levels even vaguely comparable to smps circuits would likely be a HV doubler with large filter capacitance and low effective supply impedance, or a high current heater supply being rectified for DC, or just simply any power supply with exorbitant levels of capacitive filtering (ie. in the one-eyed pursuit of more hi in hi-fi).
There are lots of hidden benefits in purposefully aiming to reduce diode current peak levels - for starters, valve diodes are excellent, and similarly adding extra supply resistance, and reducing first filter capacitance.
That said, I happily bought a batch of UF4007 for restorations and just use them (2 in series for most B+ secondaries, and parallelled diodes for more stressful supplies).
