As George2 states,the best way to know for sure is with experimentation.As he states,they both offer return policies.PS Audio,Equitech and BPT all offer balanced power.
This in itself is a very effective technology.The differences are this.The BPT products offer a no bells and whistle approach.Still a very good product and cheaper than the Equitech, just much simpler.The Equitech products offer a transformer that they call a "Q" version that is supposed to be better for a/v products.Nicer chassis,on/off switch,etc.,that raises the price.Once again,another great product.Last but not least,by any means,there is PS Audio.
PS Audio offers balanced power out,but also have complete ac regeneration,to completely clean the line.The only drawback to this is that they are only about 50-60% efficient.They also offer a Multiwave option that allows you to change the frequency and waveform that your equipment sees.They also have voltage stabilization,that the others do not.These products have received rave reviews from a lot of people.The only problem being the bang for the buck.These are by far the most expensive,but they also offer a lot more,and as they say...."you get what you pay for"!
