Transformers .. Is It Just Me?

I have 2 line conditioners in my system in series -- the SR PowerCell 10SE Mark II (according to Ted_d's information, thanks) plugged into a Bybee Stealth. Frankly, with my recent experience with an isolation transformer, if I had to do it all over again I would have made different choices. I think I could have had a lot more bang for my buck. Let's just say that the Bybee Stealth made it worthwhile.

After experimenting with a lot of Bybee products I have come to the conclusion that it is hard to do too much AC cleaning. Lately, I have been doing research into balanced conditioners, isolation transformers and power regenerators. Since I live overseas it would cost an arm and a leg to have one of those mammoth balanced transformers shipped over -- not to mention the cost of the item. This is beyond my budget. So I have been looking at relatively inexpensive "alternatives". I cannot afford a balanced conditioner or balanced isolation transformer at the moment so I decided to gamble on a relatively inexpensive medical grade isolation transformer.

I found what I thought might be a good choice on Ebay. (I also found an inexpensive power regenerator. That's a story that will have to wait for another thread.) I just put this isolation transformer into my system and have been doing some A/B-ing. I have read where non-balanced transformers will have minimal effect -- but I did read (I lost the thread) where one Audiogon poster was not convinced of this. My initial experience -- is it just me? This is amazing. The holographic effect with this unit in my system is astonishing. This is unmistakable. When I unplug the unit the air around instruments and vocalists is gone. The sound is still holographic but it is not the same at all.

OK, the unit has a hum due to the internal fan. But with all but very low volume I cannot detect it. I'll have to work on damping the hum. Has anyone else had a positive experience with a medical grade isolation transformer? My unit was made in Germany by Block, by a top maker of transformers. It weighs about 40 lbs. and the toroidal is encased in resin. Do different medical transformers give different results?

Ozzy,
I have my transformer first, then my PowerCell. I have read 2 threads where others have tried daisy-chaining like were are doing. They both got the best results from putting the transformer first -- before the conditioner. I followed their lead and it does indeed give the best results in my system.

Pehaps mine just needs more time to break in. When I get the used units, one of them will be put before the Synergistic powercell.

Ozzy,
Mine needed no breaking in. Please report back when you have all 4 in your system.

Well I just received my other 3 Isolation transformers.
I now have a total of 4 of them.
One is before my Synergistic Powercell and the other 3 are plugged into the Powercell. One is used for digital, one is for analog, and the other one is for my Home theater equipment.
My Pass Labs Amps are still plugged directly into another dedicated circuit.
Yesterday for the first time, I got to try them all together.

First, the Video, what excellent picture quality, I am seeing better colors like a little more greens and yellows. Picture looks pretty sharp and natural.

On my Audio, everything sounds so clean, it sounds as though the soundstage moved forward a bit.
To my surprise with this now sharper sound, I can now hear more warts in the recorded sound.
An example of this is on the SACD "Wish you were" song by Pink Floyd. The main guitars in the middle of that song now sound distorted, but, then I realized it was supposed to sound like that! I noticed it right away it is now very clear.
I'll still be playing around with different placements of the Iso Transformers and perhaps try it on my Pass Power Amp sometime.

The only drawback right now is the slight transformer hum I hear on the Iso unit that is connected to the dedicated line that feeds the Synergistic Powercell. It must be because it has the most current draw.

Ozzy,
I'm glad to hear you are getting such good results with your transformers. I also have a hum on my isolation transformer plugged into the wall but it's no problem since the music drowns it out.
