Indeed, this will cause minimal current limiting in a conditioner. The flip side is that one can't produce more than 6db/octave (first order) noise attenuation, starting that filtration far up into the noise spectrum and is incapable of providing any material noise isolation between outlets.I was wondering how you could claim isolated circuits in your Busss, but now I see how multiple RFI cores could provide measurable isolation, albeit over a narrow portion of the noise spectrum.There are vendors who feel a material amount of series inductance (what you're call current limiting ) is a good thing, like Audience, Running Springs,mysef and others, and their customers use them quite happily on many different power amplifiers, nor do they complain of limited dynamics. The series inductance/shunt capacitance filter allows stronger filtering (>=12db/oct), starting significantly lower in the noise spectrum. No doubt, there are some amplifiers that work better with capacitive, parallel filters, or none at all. I've yet to hear any mains powered switching amp that was listenable without a series inductance/shunt capacitance (or balanced) power conditioner feeding it.FWIW,Paul
jtwrace, dBe, Occam and everyone else interested in power filters (not surge suppressors)... The best way to do power filtering is this: For low level audio components such as CD players, DACs, preamplifiers, phono preamplifiers, anything video/digital, etc. the best method is to use an isolation transformer per outlet (per component) followed by a parallel capacitive AC line filter (after the isolation transformer).For power amplifiers, DO NOT USE isolation transformers (unless you want to slow down the slew rate transient response of your amplifier). Just use a parallel capacitive filter (not series inductor - unless you want to slow down the slew rate transient response of your amplifier). That's it! Simple as that! This is the proper way of doing power filtering for audio and this is the BEST way. Period. I just took the myth out of power filtering for all of you. And this is simple enough for anyone to construct themselves. No need to wonder about any magical PI Audio, PS Audio, Transparent, MIT, etc.For surge suppressors you have only 2 options: MOV based (everything else), or Series Mode (I.E. Zero Surge, Brickwall, SurgeX, Torus). Both have their weaknesses and both have their strengths. NEITHER is better than the other. BOTH have negative effects on power amplifiers. BOTH are current limiting. Thread closed.
jtwrace - Who in their right mind would embark on this nonsensical time consuming project? It's OBVIOUS that those circuits are current limiting, OBVIOUS. To actually test the Zero Surge unit and publish the data in a fashion that YOU would understand is an involving, tedious, time consuming project. However, I will do it for you! I even have a Zero Surge unit myself, so no need for you to send it to me. I will however need to charge you for my time, $90 per hour for however long it takes to complete the project. If you're seriously interested, I can give you a better estimate in how long something like this would take. I will need a 100% up front payment before I even touch anything.
This thread has two strikes FYI
Paul and Dave,When you discuss the use of conditioners on switching amps, are you refering to those that use switching power supplies or are the linear power supply Class D amps in the same camp too?Thanks-Mike
jtwrace,Wouldn't a cheap clamp style amp meter be enough here? I assume you don't need to test the limits of the components but more or less if the current is limited when plugged into the PLC vs the wall.
Sorry for the OT. Mike asked and I answered. My bad. Divergence as a way of life, I reckon. Dave
You had nothing to do with it. I got no beef with off topic stuff in a thread like this.
I thought the same thing but according to this thread, no.
jtwrace - Connect the amp directly to the wall, connect the oscilloscope to the output of the amp. See how it responds with square wave, extremely short impulse signals, very high frequency signals, etc.Now connect the amp to the Zero Surge unit and repeat the above. Compare the results.
