Custom Bridge Rectifier on a preamp power supply

I need an advise from any memebers with experiences in custom bridge rectifier. I am thinking about building my own bridge rectifier. Can i mix two different diode ( 1 pair of Fred and 1 pair of Schottky)?? From my expereinces A Fred diode gives me more of a relax sounding( laid back, imaging are much laid back) and a Schottky diode ( dynamic, was more of in your face sounding) too much of forward sounding. To compomise, is it possible mixing two pair of diode together? Any advise are much appreciated!

^^ I was trying to keep my response simple!

I saw a really simple solution that involved the use of a tube rectifier, which due to its linearity does not induce swept inductance issues. It was bypassed with a set of ordinary diodes. So when the diodes cut off, the tube rectifier took up the very brief load, preventing the resonance from getting started... only works if you have the winding for the filament though... and the room :)

Basically i can not mix diode. I am having problems with the schottky diodes, they seems to be in your face ( too forward). Is there a reason for this? Is there a way i can fix this, or it's just the character of Schottky. Please advise??

Actually I mentioned why that is in my first post on this thread.

There are various types of Schottky(as well as FRED) diodes. ie: Just within those Schottky diodes manufactured with Silicon(as a semiconductor); a variety of barrier heights are available, that result in differing Current to Forward Voltage curves. Some(like ZBD Schottky diodes) are manufactured with Gallium Arsenide. Like the various capacitor and resistor types; each may result in a different presentation, depending on the rest of the circuit. How many different Schottky designs have you tried?
