Hi,
This topic has been discussed here before.
Anyway I would like to post it again.
I run my (revisited) Zen with about 30000uF
capacitance in each channel.
Recently I replaced some of the caps with
a (semi)regulated power supply from
the Power Follower99 by A.Ciuffoli
http://www.geocities.com/ResearchTriangle/8231
(with 10000uF in front of the circuit)
I should note that with the caps there is some hum
(audible at about 20-25cm (maybe 30) from the speakers).
With the virtual battery (the name comes from A.C.
page) there is no hum whatsoever.
The sound is pleasant, but misses body and air; there is less bass as well. I don't understand this.
As Zens draw constant current for the PSU, it shouldn't
matter how fast the PSU is. Maybe the (semi)regulation circuit reduces the current (substantially).
Can anybody write a few words?
Greg
