Power supply to Amplifier

Rlwainwright, you're right - it won't do a thing when lightning hit is direct (1 foot wide plasma) but it will help when it hits transformer, street light, ground near your home etc. The best is always to unplug and I do it during thunderstorms or when leaving for few days. For everyday use my amp is ON all the time protected by Furman. My DVR and TV are also plugged-in since it is recording shows during day.

Also, Al has very good point. It doesn't have to be lightning. I experienced few times light bulbs going slightly brighter for a second or so and in one case Furman's circuit breaker switched off. Voltage reached dangerous level without any thunderstorm in whole area. Such things like inductive kickbacks, that Al mentioned, would not be noticeable but could easily damage electronics. My Furman filters them out and suppresses them without even engaging circuit breaker.

To connect the Amps direct to the wall socket is the way to go for High current draw SS amps esp monoblocks. But i did the following when I upgraded my power supply.
a. 30 amp feeder direct to board
b. 20 amp feeder direct to board
Connect in a Shunyata Hydra 4 to one of the Oyaide R1 duplex outlets for the 30amp feeder. Plug in my Preamp and Phono to Hydra 4 direct. Plug in my Acoustic Revive RTP-2 ultimate in 1st Shunyata outlet driving the two mono AN300B SETs. I use the 1st outlet on the Hydra 4 closest to the magnetic breaker. So I had 5 outlets if you know what I mean but I have now 1 spare outlet.
The other R1 goes to a 6 outlet BPT 1200 Power Condtioner (balanced) powering my Mcintosh CD player and the PWD DAC II, Subwoofer amps.
The 20amp circuit drives my router, NAS , also, Media server, and T/T motor unit. etc

I tried to plug the Acoustic revive with the 2 monoblocs AN300B's direct into 2nd Oyaide R1- Ground differential Hum even though it was the same 30 amp circuit. After it is routed through the Hydra 4 - no more problem. Lucky I did that cos' shortly after that I hit a earth fault as I was messing around with some wiring in another circuit, and trip the entire main board breaker. Could have blown my amps or something.

SQ analysis. RTP-2 Ultimate is really great in a subtle manner. Seem to tame the Shunyata darkness if you guys know what I mean; More alive the music!
So SQ goes up, protection is still there; Not ideal and purist but I feel safe! Not to mention thunderstorms and lightning strikes?

Heheh...a little input on surge protection for the non-believers, of course I pulled this off the internet. I doubt my wording would surpass it.

The primary function of surge protectors is to protect sensitive electronics and appliances from dangerous spikes in electricity. Spikes can be caused be lightning, turning on and off high-power devices, and rapid changes in electrical current flow. Surge protectors absorb the sudden burst of electrical current so that the connected devices do not.

Some surge protectors can only handle one big surge before becoming ineffective. Surge protectors with higher joules ratings can handle larger surges and may be better at handling multiple smaller surges.

Dang shame leat expensive ones do not come with fault lights, huh? :)

Hi Everyone,
Somehow this thread got diverted on power supply line in general (dedicated line highly recommended ) and Surge protection used by most. Also many or most prefer to lug the Amp directly to wall outlet. But not too much is shared or said as to if Regenerated power is good or bad. Is there a technical problem to use Regenerated power ? Elizabeth surly says not to use Regenerated supply. Some say it will compromise Dynamics ! Al says he does not see how , and I tend to agree with him .
At the End I like to continue with direct wall supply with my MIT ZII cord to my Amp. And yes , I do have a dedicated power line , total isolation from my home supply , and a Brickwall Surge Protection unit on my dedicated line, a servo controlled voltage stabilizer to to take care of variations .

Hi Radni,

Note that what I said was:

With a class A amplifier, which draws essentially constant current all of the time, I don't see why a regenerator would compromise dynamics. On the other hand, it does perhaps seem understandable if the amplifier is class AB or class D, where the current draw fluctuates widely with the dynamics of the music.

In the case of a class AB or class D amplifier, I can't precisely explain why there might sometimes be a perception of reduced dynamics when a regenerator is used, but intuitively I would not rule it out as being a possibility.
