Default PassLabs power filtering???

I just noticed that (to me) it seems like the passlabs power amps are sporting a "RC" filter, why have such been chosen over a CLC filter??

My guess would be cost, but this is only a guess and I do not know for sure.

Cost and space saving, my guess.

An inductor with enough inductance to smooth 120 hz and carry 10A DC continuous without smoking or saturating is not a small, pretty, or cheap thing. A few volts lost in a resistor is a much cheaper (and more compact) solution.

It's kind of six-of-one-half-/-half-dozen-of-another. CLC
gets the nod when you are trying to be efficient. CRC is
an interesting alternative when you can burn the watts.

We do both, and we make up our mind for each product,
based on all the considerations you can imagine.

I have a 1mH, 20 A inductor from a Trygon power supply -- could be used as small boat anchor (weighs 6kg). Anyone interested ?

The problem is you need 4 for a set of monoblocks

Let not your heart be troubled. I think there was a typo in Mr. Pass's answer. "6 of one-half" would be equivalent to 3, after all.

("6 of one or a half-dozen of the other") is what I'm assuming he was getting at.
