Power Conditioning / Surge Protection

I am looking for some advice on power conditioning and surge protection.  I have a dedicated circuit for my two channel system with eight outlets. Years ago I was talked into buying a couple of Richard Gray Power Stations which I still have in the system. Because of the logistics of my system they have served as additional outlets when power cords weren’t long enough but honestly I don’t know a damn thing about power conditioning or surge protection and whether I’m doing harm or good to my system.  I have a turntable, phono stage, music server, streamer, CD player, integrated amp and dual powered subs so I have a lot of need for power. I’m interested in protecting my equipment but I don’t want to muddy things up either. I’m willing to scrap the Richard Grays and either replace them with something else if there are better options.

I would greatly appreciate any advice from those who know about these things. I’m very happy with my equipment but feel the power issue is lacking or, at best, not well thought out.

Sorry but your example is too simplistic to be realistic. That 10V drop assumes the capacitors never charge. They do of course.


As well if there was 1 ohm resistance the spikes would not longer be 10A since current would be limited by voltage drop across the resistor (see charged capacitors above).

How would this potential loss be audible in a "poorly regulated" amplifier?  That would require you justifying that there would be more noise with higher resistance. You have not done that yet.

Capacitors charge in narrow current spikes, but they cannot charge to the same full voltage when there is voltage drop on impedance in series.

Perhaps spikes would be 1/12 less since we drop 10V of 120V.   It doesn't change anything.

I did not say more noise.  I believe that amplifier with less regulation will be less linear with changing power supply voltage.  Less linear = more distortions (like loss of dynamics).

Jeeeez    I tried Richard Gray and they were awful in my system.

So you think large spikes every 120th or 100th of second causing large voltage spikes with high harmonic content is going to create less noise and distortion than a slowly changing voltage at the same frequency? What is the music peak is at 180 Hz or above?
