Best Power Supply for Pass Labs Aleph (X)Ono

[dtm1962]

I have noticed three types of power supplies for this fine series of phono preamps:
1) Mosfet Output/Lower PS Cap. (8000uF) & as standard for the Aleph Ono
2) LM317/337 Regulator based with higher PS Cap. (>40000uF) for the (X)ONO Clone
3) Possiblly dual 7815 & 7915 configured to create +/-30V Reg ($ >120000uF) for XONO

In your opinion (ignoring the benefits of a dedicated power supply for ech channel as used in the XONO & (X)ONO clone) which configuration is considered the superior regulated power supply?

What the benefits and disadvantages of each configuration in regards to sound quality benefits?

Any input/experience would be appreciated.

Thanks in advance....

I'd like to hear what people think on this subject as well. To add another to the mix, what about a Salas shunt reg?

The Ono is not particularly sensitive to the power supply as the MC head amp already has a capacitance multiplier. If you really want to improve things, replace the cap multiplier with maybe one of these opamp shunt regs. But then you would need to do your own pcb-artwork...

Have fun, Hannes

PS: remember to place the regulators always close to the load - a regulated psu in an external enclosure is only a sign that no regulated PSU is needed

Where do you buy this Shunty Regulator board/ stuffed or without components?

Is there a commercially available Shunty Regulator PCB board available for the ONO?
