Power Help - What Conditioner - WHERE?


I have a large HT/Audio system and have accumulated a good number of power devices, but want to use them for maximum effect and ask for your thoughts.  Here is a list of my Conditioners:

1) Emotiva CMX-2 (Thought I had DC issues a few years ago, only has to outputs)

2) Sound Application XE-12 (not used currently, but many outlets labeled analog & digital)

3) BPT BP-2 (I have one of the originals with 8 total outlets (1500va I think)

4) BPT BP-3.5ish (Chris Hoff built this as one of his final builds using a 3000 or 3500 va transformer)

5) Various Power Strip for connection of wall warts etc.

I need to connect the following (long list). I have a dedicated 15a and 20a circuit to my rack.

a. Emotiva XMC-2 Processor/Preamp

b. Oppo BDP-203 MultiDisc Player

c. Rega P8 Turntable (Wall Wart)

d. Musical Surroundings Nova III Pre w/Linar Power Supply (Wall Wart)

e. Apple Mac Mini (Std 2-prong power cord)

f. Western Digital (2) USB HD to the Mini (Wall Warts)

g. Drobo Raid HD (2) to the Mini (Wall Warts)

h. Eversolo DMP-6 Streamer (IEC)

i. XBOX (Std 2-prong power cord)

j. CableBox (Wall Wart)

k. Adcom 7300 5-Channel Amplifier (Powers Rear 4-Speakers) - IEC 

l. EAD PowerMaster 1000 50Channel Amplifier (Powers Center Only) - IEC

m. Parasound 2125 v2 Stereo Amplifier (Bottom bi-amp of Main) - IEC

n. Custom 60w Tube Amp (Top bi-amp of Main) - IEC

o. Router/AP for Basement - Wall Wart

p. 8-port Network Switch - Wall Wart

q. DIRAC Network - Processor box (Wall Wart)

r. NHT SA-3 Subwoofer Amplifier (IEC)

If you are here - THANK YOU for reading. How would you suggest I connect everything? Should I only connect via the 20A circuit, or use the misc (Network etc) connections to the 15a service/circuit. What would you connect to each other. Redoing my rack is a HUGE task, and I would like to get power - RIGHT. Thanks for your help.

That’s a lot of stuff. The best would be to connect the minimum for a 2 channel stereo in one location and to a direct line. A power conditioned for the streamer through turntable through preamp… and amp in the other socket. I’m trying to be realistic… most of your equipment is modest.. so you don’t want to get carried away.

 

Then move the rest of the stuff as far away as possible, different room.
 

If you have no choice but combined HT and audio… not a great choice… same deal.

 

let the power conditioner (s) be priced appropriately… like on the order of cost of a good component in your system. Look to Shunyata, or IsoTech. 
 

The best systems have the fewest high quality single function components in one location. An ideal system today is a high quality stand alone streamer, DAC, Preamp and amp with a power conditioner for everything except amp. 

Furman P-2400 - 20A with built in voltage regulation, series mode protection and linear filtering.  

The one caveat is that for any power conditioner you run into the issue of attaching dirty power supplies to the clean side and re-polluting it, even with multiple filter banks. 

If you run a lot of wall wart appliances like switches, Roku, etc. you may want to add a separate PST-8 just for them or use iFi power supplies. 

And for sure, keep your PC/laptop supplies out of your clean power side. 

Furman power conditioners don't improve sound

 

we would recomend  using two conditioners one for your amplifiers

 

and one for other devices

 

our very large reference theater uses two conditioners

the we use an isotek sigmas for the rest of the system

Thanks for the input guys. I am trying to use the equipment I have already acquired. I have the XE-12, but it is not in use. Lots of outlets. Full 20a connection. I also have the two BPT units. The Balance Power BP-2 is 15a and the BP-3.5 is 20a. I am pretty sure if I connected all of this equipment via the 20A circuit, we would have enough current/amps, but I am open to discussion of using one of the BPTs to be dedicated to my wall wart stuff. Challenge is much of it ends up back in my Pre/Pro, and if I understand my reading/research, I am better off putting all devices off that single circuit?  If yes, what order? XE-12 to power the BPT units, and then connect all my Pre/Pro - Source equipment to the smaller BP2, and the Amplifiers to the BP-3.5?  With all these wall warts, I will need to use a power strip that better handles their configuration.

 

Your Sound Application XE-12 is a wonderful unit. I'd be trying to hookup as many pieces to this unit as possible keeping the digital plugged into the appropriate outlets. Keep in mind to use a very good ac cord from wall to the Sound Application unit. Yes it uses a 20amp inlet but you can buy an adapter for using a standard ac cord. Good luck.

Are you saying not to use any power conditioning equpment for 2-Channel? I am a full believer in the BPT, as it has really dropped my noise floor, but looking for ideas for the entire rack. My Pre/Pro is the master of all of this, so I think it needs to be on a BPT. Appreciate your thoughts.

The amp is the only thing you want plugged into the wall without power conditioning. The rest of the equipment should be on power conditioning. 

@ghdprentice spot on

If you don't have separate lines, then plug audio gear into your best conditioning device and everything else into a separate one, such as a surge protector etc.  Preferably they would be on separate lines but otherwise another outlet is preferable. 

If you have any nearby plugs that run on a different circuit, consider running a line or surge protector on that line with all your AV.  If this isn't an option, just do what @ghdprentice said.  I would also try unplugging your digital from your main power conditioner and see if that makes a difference sonically. 

I am not familiar with the devices you listed for power conditioning etc but ultimately the main thing is separating your audio components from the noise of the rest of your AV system.  I have this same issue in my living room.  I have a fairly high end shunyata power conditioner though and I plug my noisiest stuff into the digital side(TV, other digital devices) and my amplifiers (active subs, main amplifier) into the analog side.  This is what Shunyata instructed I was happy with the results.

If you can afford an older Shunyata unit at some point (MPC-12, older Denali units, Hydra units) I highly recommend it, although I have never used the stuff you've listed.  After using one in my studio I finally found a super good deal on an MPC-12 and pulled the trigger for my AV system and it made a world of difference.  At the end of the day, if you just follow these instructions, that's probably the best you can do.  Also last note - separate cables as much as you can.  I know it's a rat's nest but separating power from speakers/interconnects/other power cables as best as you can is important.

Here is a bit more inffo.  I have two circuits sitting right at the back of my AV Rack. One is 20a and the other is 15a. They are dedicated and wired straight to the box.

Do I take "Noisy" equipment (PC, Drobo/USB HD, Network Switch) and connect them to the 15a circuit, even though the PC connects via HDMI to my Pre/Pro for playback of Movies and Music? I would run this through a BPT BP-2.

Amplifiers, I was planning on using the BPT BP-3.5 for all my amps, and then connecting the BPT to the XE-12 which would be the only device connected to the 20a circuit. Is that a good idea?

Again, remember I already have all this equipment. The XE-12 does remediate/filter DC power out of the line, so no need for my Emotiva CMX-2.

Basic set-up 101:

- Plug the digital components into the BPT 3.5 balanced power conditioner.   Plug this conditioner into the 15amp circuit. The digital components don’t draw much load. 

- Plug the analog components into the XE-12.  Plug it into the 20amp circuit. 

- The XE-12 does not appear to be current limiting.  It should easily be able to handle the amp.  Listen with the amp plugged into the XE-12 and then listen directly into the wall.  Be sure to wait at least an hour before critical listening.  A quick A/B comparison means nothing.

- If possible, put the cable box/modem/router/switch on a completely different line and/or room. Plug these into the BP-2 power conditioner.   Or - temporarily run a heavy-duty extension cord from a 3rd circuit in a different room for these digital units.   This experiment will give you an idea if it’s improving the SQ.  Make sure that the 3rd circuit is actually independent - and not shared by the same leg on a common wall.

- - -

After everything settles in for a few days, unplug only the HT gear completely.   Critically listen to the 2 channel audio only for a few hours.  Then start plugging in the HT components one by one - and turn each on.  You’ll hear how the SQ changes.

- - -

Isolating analog from digital is very important.    And isolating digital from digital is also important.   Digital components regurgitate noise back into the system circuitry which affects the other components - both analog & digital.  It’s a cumulative effect.
