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?

Vey interesting. Can you tell us where you bought it, and the price? I did a brief search, and saw Tripplite models of various prices. How do you know what to buy?
Roxy54,
I bought it on Ebay for $350. I know this is a lot higher than some other brands offered on Ebay but this model enables me to convert the voltage externally to 230 volts and I was also impressed by the high quality of this made-in-Germany unit. In any case, it was definitely a gamble because I have absolutely no experience with these units (medical grade) or with balanced transformers.

The common wisdom is that you need to go balanced to get sonic improvements. The fact is that I am left stunned by this unit. I have been listening all day with amazement at what it does in terms of realism and "being there". Uncanny. These are some of the best $350 (+ shipping) audio dollars I have ever spent. But I must caution -- YMMV. I have never seen another unit of its kind advertised anywhere. I have no idea if other medical grade transformers will perform the same wonders.
Here is an article I found that might be helpful
