I need a minimum of 4A for the GRAID drives.

But Steve,
You can always use an isolation transformer (proper one). ;-)
I wonder what brand and model would constitute a "proper one" for YOUR APPLICATION. It's easy to be vague.
A superregulator powered by an ultra isolation transformer will have much better bandwidth and isolation.
But it won't power your disk drives because the designs I've seen won't supply the necessary current. Besides, these 'superregulators' are designed for audio circuits, not for supplying the current demands of HDD motors.
Your HDPlex power supply is very well suited for YOUR APPLICATION, which some folks here can't seem to grasp.
Abe,
Fred's design puts out 2A. I need 4A. You obviously know what you are talking about.
Which specific 'superregulator' design (by whom) and what version is Fred suggesting? There are several out there that claim to be 'superregulators'.
Is there an online schematic of the specific design he is talking about?
not a problem, just uprate the power transistor.
But this was not my point. My point was that the LT 108x based PSs are at best slow and mediocre, with limited bandwidth, and that 2nd hand opinion needs to be processed and not just repeated in a discussion of any value.
I am sure that you must be aware of much better PSs if you visit Computeraudiophile.com
I have no doubt I could purchase far more expensive power supplies. Would there be beneficial sonic results? I really don't know. But I do have something coming that might shed some light on this.I do know that the HDPlex sounds better than the SMPS. But then again Fred, I NEVER stated that this was a state-of-the art solution.

you have just said was what I set out to say. Really there was no need for this prolonged and defensive exchange.
