Well, I received one of the Iso medical grade Transformers yesterday.
I have it installed before my Synergistic Powercell into a dedicated 20 Amp circuit. All of my equipment (video and Audio) is plugged into the SR Powercell except the Amps.
Now, this is a brand new unit straight out of the box. The other 3 units will arrive next week and they are used units.
First impression, the sounds does sound quite a bit cleaner, deeper and clearer. But, there is a sharp hardness to the sound. I believe this is because its brand new, consisting of new power cord, new outlets, new transformer, new electronics and etc. It will take time to settle in. But even at this point, I believe its a keeper.
On my LCD TV the picture is quite a bit sharper, the colors don't seem as vibrant but the image is very defined. For example, on the Fox program "The Five" I could see just how much caked on makeup Kimberly Guidfold uses.
So, I'm going to let it break in a while, and then soon I will have the other used units for isolation of my Digital, Analog and Home theater equipment and see how all this develops.
Thank you Sabai for starting this thread.
