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)?

The metal braiding in the Belden 83802 is unwove and used as a ground or you can add an additional ground wire gently wrapped every 3” on the outside of the Belden. See: http://www.venhaus1.com/diymains.html
Harley: You have enough transformer in the Tice to run ONE good sized stereo amp and that is all. You might be able to get away with two amps if you listen at rather moderate volumes or have high efficiency speakers. Ideally, you wouldn't have anything capable of pulling more than about 1000 - 1200 watts hooked up to the Tice. I have NO doubt that this is causing some of your problems. The Tice might be capable of supplying the quantity of 1800 watts of power but that doesn't mean that all 1800 watts would be of the same quality.

Try plugging the amps directly into the wall and see what you get. While the sound will change due to the noise floor increasing, you should be able to hear a drastic increase of dynamics under load. Even plugged into the wall directly, you are probably going to run into current starvation if you really stood on the throttle. I have amps that can pull 20+ amps individually when really cranking things up on low impedance, low sensitivity speakers.

Just because you have six outlets on the Tice does not mean that you can hook amps up to all of them. Doing so would be like assuming that you have money in the bank simply because you still have checks in your checkbook. It just isn't so.

With what you are trying to run, you really need a dedicated 100 amp breaker box and the associated dedicated wiring / outlets just for your system. Sean

Thanks Sean

Subaruguru has been really helpful and has echoed the same meassage .... go dedicated & use belden 83802 power cables.

I am in the process of disconnecting the amps and running only one until I have a remote sub panel installed (6-8 AWG) and then run Belden 83802 to new dedicated solid metal boxes with 20A hospital grade Hubbles (cryo maybe).

Since I am going to build a dedicated room in the next year, I will float these boxes and re-locate them to the new room.
Since they will be floated in the attic, I can take them with me if I move ...

2 20A circuits for 4 OCMs
1 20A circuit for the 350As
1 20A circuit for the Subs
1 20A for the front-end / Bybee Pro.

The existing 15A will be used with the Tice for the TV and other basic components.

Appreciate all the input from everyone.
It has been quite helpful and appreciated.
New power.
125 amp (4 AWG) isolated ground panel
5 dedicated 20 amp circuits (10 AWG romex)
1 single 20 amp circuit Beldon 83802 (didn't have 500 feet of 83802 or another $1000 at this time) ...
All IECs are now Beldon 83802 / hospital grade / lifted grounds.

The only noise is from the recently upgraded Anthem AVM 20.
There are no satelite / cable TV connections / not on top of any electronics .. just a CD player.

The floor is so silent that the transformer noise from the AVM 20 can be heard across the room ... what a pain.
I just contacted Sonic Frontiers to ask why ... will update with their response.

Other than the AVM 20 the improvement (and peace of mind) is dramatic ... even the new AVM 20 software is awesome ... but that noise!!!!
Glad to hear that things are pulling together for you. Sounds like you had the electrician busy for a while. It's not unusual to think that you are done only to find yourself with yet another project that came about as a result of the other "upgrades" you just performed. I think that we can all relate to that part of the equation : ) Sean
