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.

Synergistic Research PowerCell is outstanding.  You can shop for a PowerCell 10 FET/UEF, or the better PowerCell UEF SE.   An older version for less cash is the Tesla PowerCell 10se MKIII.   A newer one and better than the others is the PowerCell SX.   The power cable connection is a Neutrik bayontte PowerCon, so it is a special termination on the PowerCells.  Scott Walker Audio or usaudiomart are excellent places for good prices too.   good luck.   

@drdetroit if you have not already done so, pay attention to your grounding strategy in order to determine the effect of your power conditioning. Puritan for example make the 156 power conditioner that can also be easily grounded using their City Master plug in device. Not horribly expensive. Hope this helps. 

What are your goals? Nothing you will do here will affect how any of these perform. And power conditioners really do nothing but potentially reduce output or add noise to the chain. Just go get any decent large power strip.

Trying to help, or internet banter? I hope the former. Nothing I do here will affect how any devices perform? I disagree, otherwise, I would not have this equipment and be trying to optimize. I have many decent power strips, but find the Balanced Power Technology products do lower my noise floor.  As I prepare to reconfigure my rack, I was seeking the opinion of other Audio folks. You have chimed in, and I will properly consider your input.

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. 

I don’t know if that’s a good idea. Feeding AC power from the BPT 3.5 to feed some equipment and feeding other equipment from the AC mains wall outlet. That is, where the equipment will be connected together with wire interconnects.

You will be mixing two ac power systems with different types of grounding, bonding the neutral to ground. They are actually connected together at the main electrical service panel.

Best practices, when using separate branch circuits to feed audio equipment, when wire interconnects are used to connect the signal from one to another, the Hot conductors of the branch circuits should be fed from the same Leg, Line, in the electrical panel.

Here are the results from a bench test I did recently. I wired a 2KVA isolation power transformer, primary 120V, secondary  60V 0V 60V. Center point of the two 60V windings (the not used neutral conductor) bonded to the case of the transformer and connected to the equipment grounding conductor in the power cord that plugs into the 120V mains wall outlet.

Measurements

Output of BPT.  From the receptacle identified Hot contact to the Hot of the wall outlet I measured 60V nominal.

Output of BPT. From the receptacle identified neutral contact to the Hot of the wall outlet I measured 180V. (If you draw the circuit/windings on a piece of paper a 60V winding is added to the utility power company 120V winding used to feed the wall outlet. 120V + 60V = 180V.

Even if the two BPTs are used to feed all the audio equipment, they should be checked to verify the two outputs of the transformers are in phase with one another.
