how many folks have +10kVA trannys before the rig?

Jeffcott, if by "downstream iso", I assume you are referring to the small 125va iso on the CD dedicated line. That iso, while next to the subpanel and large iso, is only 15 ft. from the CD player. Note that I mounted it at right angles to the main iso to minimize any cross coupling. I have tried the small iso in the room on the CD, and tried it as presently mounted, and could not perceive any difference. Note also that the class D amps in each speaker are on dedicated lines but not through the main iso.

Zargon:
Yes, that is what I was trying to communicate. I hope that you understand that I meant absolutely no disrespect by quoting what the documentation says. I can think of a thousand reasons why an ISO might very well not be the most desirable component in a living environment. Like I tried to say, NICE install.

Jeffcott,

No disrespect taken. My comments were mearly directed at trying to pass what I learned when experimenting with the small iso location.

WRT to the desirability of having an iso in the living environment, while the small iso is virtually inaudible and only slightly warm to the touch, the large iso can easily be heard from several feet away, and is quite warm to the touch. Hence, I decided to locate both isos on the block wall just outside the audio room.

I have been using balanced ISOs in my living environment for the past 5 years; currently 1 x 2kVA Equi=Tech Q type and 2 x 250VA in a single chassis. I recently completed a rebuild in a taller chassis, to add the second 250VA transformer. The large iso has an oversized core, is very immune to saturation from DC on the power line, and as a result, runs quietly. I've tried other isos that were very noisy.

It must cost you guys $50.00 plus a month just to turn these transformers on. I tryed a tranny from GE, just to power up the coils it pulled 5 amp for a 5KVA 208vac to 110vac stepdown center tap balanced transformer. I was told by GE that the amp draw is normal, too much cost for me. I even tryed to use a starter for on off cotrol but the breaker tripped on inrush at times.
I picked up a line reactor that I am going to try soon to clean up my power. They work on VFD's to stop dirty power for getting to it or from it.

I prefer real woman myself anyway. LOL.
