To Power Condition or not?


I have 6 monblock amps (balanced bidging of Belles stereo amps).
4 are OCM 200s (100 amps of current / 400 watts balanced)
2 are the new 350A (>30 amps current / 800 watts balanced)
2 Velodyne Subs.

All front end components are through a Bybee Pro Conditioner (no amps connected)

I have been using a TICE Power block - Titan for the power amps and have run out of receptacles since I added 3 new amps. (only supports 6 power cords).

Questions:
Should I add another Tice Powerblock to expand the connections?
Should I use any power conditioning on the amps?
Should I run X+ new 20 amp circuits from the main electric supply panel and direct connect the amps & subs?
How do I eliminate the 100 Hz hum (other than lifting the grounds which seems to reduce it significantly)?

I can't believe that a Tice Power Block / Titan combo could feed all of those amps under load and NOT cause some type of voltage drop / signal decay. My suggestion is to get a couple of dedicated lines just for the amps and have the Titan converted over to a full fledged Power Block. This is not that hard to do. You could then split the current draw between the two Power Block's, which were in turn being fed off of their own dedicated lines.

Quite honestly, you really do need several more Power Blocks to do things right. With that kind of set-up, i would consider 4 Power Blocks a minimum and 6 as being "good".

The other alternative to this is to use one phenomenally huge Isolation transformer i.e. something like a 10 - 12 KVA model. You can find these surplus and it would probably cost you less than one Power Block at MSRP. It just wouldn't have the "audiophile approved" name on it. Sean

You should look at balanced power from equitech or someone else. I don't like the idea of power conditioners on amps at all. I think it limits the range of the amps. I have no problem with these conditioners on digital units such as dvd,cd and video. Widescreen review has done a thorough analysis of balanced power and its use in combo with Richard Gray equipment. Their website provides the articles
describing the use of this equipment. The balanced power mfgrs. do not particular care for anything between their units and your equip. I agree that outlets make a difference and I am sure that the PS Audio is good, but it is not the last word. I have FEMs and am very happy with them. I intend to cryo them because from what I have heard from hearing cryod outlets their is a benefit at a decent cost. I would suggest doing an outlet search here where you will find a wealth of opinions on outlets.
The older Tice Power Blocks / Titan's are NOT "normal" power line conditioners. Each unit houses a single 43 pound 1875 watt isolation transformer. For best results though, one should not be pulling more than about 1000 - 1200 watts out of each transformer, as this pretty much guarantees adequate headroom and minimizes the potential for transformer saturation. Running a Power Block with a Titan minimizes the potential for transformer saturation, but still limits you to one 15 amp circuit at best. As such, re-configuring the Titan to act as a Power Block would allow you to use it as a separate ( rather than "reserve" ) isolation transformer, allowing you the use of another 15 amps of current delivery from another circuit. So long as you keep the current draw down to about 10 amps or so out of each transformer under load, this would provide superior results than running them in the "stacked" or "piggy-back" mode that Tice suggests.

The only benefit to running the Power Block / Titan as they come from the factory is if you are limited to one circuit for the entire system. Otherwise, you've increased capacitive coupling i.e. reduced isolation by running them in parallel on the same circuit. This is due to stray capacitance. Running them off of and as separate circuits would actually increase available power to the amps and increase isolation. Sean

Thanks everyone.
I am going for dedicated circuits as recommended.

Great input and appreciate the advice.
