m = milli = 10^-3, u = µ = micro = 10^-6.
No confusion there.
The confusion is, I believe, in the use of capacitance per rail, per channel.
I got the impression one was stating <=50mF/rail/ch, whereas you were stating

That's a rare one 🙂
I have never personally seen inductors inside an A/B production amplifer before, advantages ...?
PS: Looks like a good tweeter amp .... 🙂

The L in a an rCLC PSU reduces mains interference feeding into the amplifier.
It also reduces the rectifier noise trying to feed in with the interference.

More exotic choke power supply examples, which may sound less rare to you ;
- Cello, e.g. Performance, Encore.
- Viola, Bravo model.
- From fellow forum member Mr Gerhard, bass amp for the Cerubin loudspeaker.
Example of a current production power amp with regulated output stage rails (capacitance multiplier), Orpheus Privilege.
(I was informed recently that the Sanken regulated amp got booted to obsolete stage. As the Omega man is retiring in a couple of years also, all good things come to another end)
How is the value determined ...?
Interesting , so why not more common place Dutchie ...?
Yes, you can of course quote it in terms of ripple voltage for a given load. LTspice very useful for this kind of analysis.
Like all of these things, there is no right way or wrong way up to a certain point. If you are designing an amp, you get to decide the parameters.
"I guess you discount new switchmode for audio technology then? I recommend you watch this space, some of these things are starting to do extremely well. I just bought my first pair to try and it took some convincing let me tell you. fully regulated 500W using what is basically a. . . "
I think they can me quite good if you use the right topology.

During development of my earlier power amp, I tried it on 6800uF per rail. Going to 34000uF per rail seems to improve the subjective sound. I did not repeat his experiment on the latest amp since I tested the amp with the final PSU.

Cost, market, designer's philosophy.
Same cash pays for a higher output amp.
More efficient, designer happy.
More power, customer happy.
More efficient and more power, higher sales, company happy.
Ahhh, Love the way Huber packages it 🙂 I guess i would do mine like that ....................
I have a pair of Crown D-75's that I have modified. I think they are pretty good quality. The transformers buzz, but that's apparently not unusual for pro gear. My dbx crossover buzzes also, and it's brand new.
That doesn't appear logical. If there's enough to fill up the can in the vertical position, then mounting it horizontally cannot make any difference. If you fill up a glass with water, seal the top, and then place it horizontally, the water will not "migrate" to the bottom side of the glass.
I see a huge number of potential problems with this amplifier, from the use of Fastons for signal wires, to screw terminals for power leads, to various other quick disconnect fittings on the circuit boards. All of these kinds of connectors can cause a relatively high resistance, or in the case of the screws, work loose. Heat cycling for example can make screws come loose. Any connection that's important to me gets soldered.
