Power Conditioners Through Power Regulator

Svart covered it pretty well, Monsters entire Power Conditioning good rep was built on some lower priced products long ago discontinued designed by Richard Marsh.
Chris you need to make your fortune building a rackmount power strip with an LED that trips when you blow the MOV and has an easy replaceable MOV!
For the most part unless you have know issues, spending big money on power products is only good for your gear pimps wallet!

If your service is that old, you should bring it up to date. Getting your place's electrical capacity and grounding solid will do more to improve EVERY aspect of your systems performance than a 1000 *cough* power "conditioners" ever will.

Fair enough. But readers here should not expect any power conditioner to address an electrical service which cannot deliver adequate power to the load. A vintage circuit might only provide 40 amps. A modern service needs 100 to 200 amps. Power conditioners will not alleviate power starvation.

Thanks for the advice guys. I had a bit of electrical hum that did indeed disappear when I got the Furman conditioners, and my electricity here is not absolutely horrible, it's just not super up to date / studio purposed. Besides the hum that immediately went away when filtered, I've had no significant powers with that. I am indeed renting right now.

Let me rephrase, as I probably made things more complicated than I had to. My main concern is that I'm just about out of outlet space, and a power regulator seemed like the only safe way to have 4 separate power conditioners plug in to a single outlet (running through the power regulator, which I would have hooked up to the outlet). The regulation itself would be a bonus, or so I thought. I've had no issues with my power since the conditioners, but my Sweetwater Engineer played into the whole "this will not only let you have all your power conditioners hooked up to a single outlet, but it is much better for your gear, and hey, it might even sound marginally better". Again, he is recommending a unit which has +-5V regulation, which seemed illogical to me as my power averages between 118-122, with a bad day once in a blue moon maybe going an extra volt or so up or down. He still insists it will keep it closer to a constant, "perfect", 120V. It's my understanding it is unsafe to plug multiple conditioners into a power strip, or daisy chain power conditioners, which is the main reason the regulator got brought up. If there is a simpler solution I'm all for it. 

I've been meaning to get an UPS anyways, so that seems like a solid option. Do you recommend any models? Also, it's not necessarily tripping the circuit I'm worried about, since I have a start up sequence in place, it's more fires and things of that nature. A voltage regulator was the first (and until now, the only) safe way suggested to plug everything into a single outlet. I see that a lot of these UPSs have conditioning in addition to regulation. Is it in anyway bad to run a power conditioner (filter) through another power conditioner? Even if said "master conditioner" is also a UPS and regulator? Does it also being a regulator and UPS eliminate the reasons it is not recommended to daisy chain power conditioners into each other? I've never looked into the science behind this, I've just been told conditioner -> conditioner = bad / dangerous. I assume it should be fine since it's got to be accounted for that a lot of people with UPSs have enough gear that power conditioners are going to come into play, and be plugged into it. 

Looking at the Furman F1000 and F1500 now, and reading up about them a bit. 

I don't know where all the "conditioner into a conditioner" stuff comes from so I can't speak to that and I also don't know about claims of some UPS's providing conditioning or whatever else. That all sounds like marketing type stuff to me.

Also, amps are amps. Your electrical circuit either can or can't provide the necessary amps to power the needs of your equipment. The startup sequence is irrelevant. Fires shouldn't be a concern if the wiring and circuit breakers in your place are in order and NO amount of power conditioners will magically improve that. If the wiring at your place can't provide the amps to power all of your equipment then none of this other stuff matters. Your breaker(s), assuming everything is up to snuff, will trip if you overload them. Also, voltage regulation is about providing a relatively tight voltage supply to your equipment which is good for the equipment but has nothing to do with the total amount of amps you are drawing and is the bigger concern as it pertains to overload or potential fires.

All that being said, and in the context of online UPS's, don't think of them as some sort of regulator or conditioner because that implies some sort of circuitry designed to correct or control the voltage that comes out of them. The nice thing about online UPS's is that you are basically running everything through a battery, so no regulation or conditioning is required past that point. The circuit in an online UPS is such that you get pure sine wave power free of noise and exactly at the intended voltage as a product of the ac to dc to ac to conversion process. It just naturally comes out of the battery (and subsequent circuitry) that way. Think of an online UPS as your own little miniature power station, if that helps. No further "correction" necessary.

Cheaper UPS's which aren't of the online variety may claim to provide some sort of conditioning or regulation but those aren't the type I'm talking about. Search for double conversion online UPS's. That's the kind I'm talking about. Look at www.upsforless.com to find some good deals on refurbished UPS's. APC are good as well as Leibert and others.

Thank you! Ok that's cool, I like the idea of essentially having my own pure sine wave mini power station. I'm new to DIY audio, and therefore, a rookie at electrical / electronics related issues and shop talk. Since I don't have any problem tripping circuits as is, sounds like I should be fine hooking everything into one outlet, which I'm probably going to spring for a APC or something of that nature. You seem to get a whole lot more for a whole lot less than say, a Furman, because they aren't pushing it as studio purposed though it does the exact same shit. Not sure where I got the conditioner to conditioner warning, but it seems to be bullshit after talking to you guys. The slight improved safety of my gear and studio alone seems well worth the price of admission for an UPS, so I'll start doing some research. 

For four racks of gear (LA2A, a bunch of preamps..mainly transformer balanced, a Tube Tech LCA 2A, 2 tube eqs, a 10 unit 500 series chassis, FET compressors, Mac Pro, 2 sets of active monitors, converters, etc etc), is there a ballpark of the VA I should be looking for if I were to ever have to have to use the battery back up? 1500, 2000, 2500? I hope to never have to use this feature but just in case. Also, I need to do more research but I see a lot of the Furmans are only rated at 12A. Would I still be getting the full current of my outlet / mains (20a), with the battery back up being what is only rated at 12A? Have yet to check what models such as the APCs are rated at. Just curious of what this spec means. 

Generally, filters within power conditioners have little ability to remove 60hz hum. If a hum totally disappeared it would more likely be due to the breaking of a ground loop. Just rearranging your power cord connections can disrupt the mechanism for invasive AC ground currents (the thing that causes hum). A simple power strip may have been just as effective.

I will add that "pure voltage sine wAve" power thingies are basically a red herring
What is important for audio performance is instantaneous POWER delivery. Right thinking is "enough Watts in time", not shapely Volts. UPS's, even beefy ones, have poor power transient response. Under a real load the "pure sine" will get mangled & deformed. UPS's are cool for preventing a 'puter from crashing / dubious for audio signal gear performance/ death-by-strangulation for power amps.

They are current limiting devices so if you instantly need a very quick burst of current , it's just not able to do it and audio transients suffer!
This can be a very big deal with big old traditional Power Amps!

Your breaker still lets quick transients through .
