Niagara 1200 and subwoofers

Hello, I've got my eye on the 1200 but need two of them. I have 12 pieces to plug in. I'm not worried about stuff like Bluesound node 2, Fios box,, dvd player rarely used... other than my Anthem AV receiver,  Anthem str amp, Parasound 220 x 5 amp, plus two Rythmik subs. It seems I need 5 of the high current outlets when there are only 4 total. My plan is to use a splitter to plug in the subs. Will that work? 

Also, I'm thinking of the Niagara 5000 as an upgrade because it's obviously better and has the 4 high current outlets and 12 total, and in the used market it's not too much of a jump in price for me. It actually offers less outlets than I need but I'm sure it could work,, but the size of it is the #1 negative for me.. my plan is to hide it behind my stack. A bit difficult compared to two separate 1200's. Leaning towards the 1200 especially if i can get a multi discount somewhere or used...  I have a dedicated 20 amp line but it's to more than one receptacle behind my AV equipment. I can run a 10g new line as my panel is 10 ft from my system, but not eager to move my whole 'never want to touch' stack. 

So can I use a 2 to 1 for the 2 subs? Any other ideas?

Thanks

The Niagra can only do so much.
When it comes to buzz and hum, there are a number of things that can cause it- and much of it comes down to the design of the amps and their interaction with preamps.
I know, as I had a horrible buzz when I tried to use my tube preamp with solid state. It seems the Circlotron circuit has a predilection to make noise with SS sometimes-At least that is what my dealer says.
Anyhow, when it comes to hum/buzz, try some cheater plugs (non grounded plugs) and see if it resolves the problem. If so, then I can PM you someone on Agon who can help you stablize the system properly.

Thanks Bob.
I asked AQ about the 2 units and they said to omit the AV Receiver because I'm using it like a preamp. Then I'll have enough to connect everything. 

I don't get the hum all the time. When it does come, it is every 30 seconds for a length of 3-5 seconds. 

I was eager to try that separate circuit but it didn't change. I need more troubleshooting at this point.

Thanks again.

@OP,
That bit of info makes me think there is something on or near your power line. 
Think - A Dimmer, refrigerator or is there a neon sign nearby?
Search the Audiogon library. I recall that there was another member that had a similar situation. In his/her case, there was a neon sign, if I recall correctly.

I just searched and read the thread you mentioned. The guy had a noise every 8 minutes and it was his security system. 

I do have a wireless camera nearby and a wifi router nearby. I'll have to check them at some point. It won't be easy, so I'll leave it for now.

The subwoofer is part of my HT system and I hear it when the AV receiver is OFF and only the TV is on. The sub is not on at all when this noise happens.

Anyway, no big deal. Thank you. If I ever find the solution, I'll post back here for anyone who may be interested.

Just wanted to post an update. I did run a new 10-2 dedicated circuit and plugged in the subwoofer directly to it. I still get the hum every 30 seconds or so. Sometimes 60 seconds. 

The Niagara 1200 is coming today, so I'll see what happens with the system as a whole plugged into it. I'm sure it will be a step up from the power strip i currently have.
