My work is cheap, fast, good. Pick any two.
My vote would be for: cheap + good. And I would say just build a quality VU meter, don’t worry about switching. My 2 cents.

Spot on. Making an instrument that measures meaningful parameters is a challenge. You want it cheap and good? It won't be fast then. I'm thinking delivery in about 100 years from now. I'll procrastinate until 99.9 years from now...The problem with meters on outputs of amps is that they can only measure the output voltage.
When they must say something about the power (and have a scale stating power) one would also have to measure current without resorting to a low resistance in series so a current probe.
With both current and voltage one can create a 'power' scale independent of the speaker impedance.
Creating a meter that really says something thus isn't as easy as a meter jumping up and down and really saying nothing. The latter is what most want... bling.
For that... just buy this Douk thing and connect the meter in parallel to the speakers and be done with it.
The problem with this is the pipeline latency from player to the output of the system/DAC. There is enough delay that I find that annoying relative to music beats. Then again these VU meters are not very fast so maybe it is workable. I love my RME DAC visualizations since they have such a low latency. This becomes even more important with respect to spectrum analyzer where to identify where some frequency comes in.If all you want is bling, why not just turn on the visualizations in your media player?
If only there was someone who could find out ...How noisy was that equalizer though? The few I played with years ago had significant noise.
I can do the testing but not the buying.If only there was someone who could find out ...
Some of those oldies add a little hiss to the output. I don't remember this one being horribly bad or noticeable. As a plus it has pink noise and should have a microphone too.How noisy was that equalizer though? The few I played with years ago had significant noise.
I can tomorrow, just don’t want to lead you away from testing important things.I can do the testing but not the buying.
Vu or LED power meters- I like to know how fast I'm driving my amp- like the reviews.....Many of us want VU meters without having to pay through the nose.
I'd be on board with this.

How about displaying the average and peak voltage on some 7-segment LED displays? Could even be in amber yellow, Amir's favourite colour. Maybe have it update twice a second or something.

GarooowlZZzzzz . Luxman M-03... I don't suppose you have a C-03 too?My Luxman M-03
Is the display even readable with zero hold time?Switchable nominal 4, 6 or 8 R with peak hold times of zero, 1 and 3 seconds. Range switch to make the most of the display.
Why not use a current transformer like your little project for I sensing?
Me thinketh you've been partaking in the medicinal herbs. Not that there's anything wrong with that...Dual scales c/w RMS Watts and Volts peak individually selectable for each meter.

A current transformer did occur to me. That may be an option. The transformer bandwidth seems to be dependant on the sensed current, which is probably not ideal.
