Has anyone considered replacing the factory power cords on the Beolab 50's with an aftermarket cord?
If so, which ones did you use and did it improve the sound?

How would replacing the last couple of meters of a dozen or hundred miles long power string improve the sound of anything?Let alone a digitally controlled amplifier?Let me tell you - it doesn't.
Seriously, this is nothing but nonsense and "audiophoolery".Sticking a photo of Einstein to the bottom of your speakers would be much better in my opinion.

No, it's not nonsens.
Did you give it a try?
Just make sure that the phase wire is right hand twisted and the negative left hand twisted, this will help with channel separation
Collecting Vintage B&O is not a hobby, its a lifestyle.
koning:No, it's not nonsens.
It absolutely is nonsense, anyone who would claim otherwise is either -
a) not of a technical background and is taken in by charlatans, or
b) a charlatan!
Ban boring signatures!
Or
c) they are just trolling
Yes it's absolutely nonsense.

I'm afraid I'm recovering from the BeoVirus.
Have you tried it?
koning:Have you tried it?
With better cables the tone is warmer, the soundstage is more crisp yet soft, and a hint of cinnamon lingers in the air. Same as for vinyl but without the snap, crackle, and pop, and light aroma of kirsch. Trust me, I have electricity in all my homes.
koning: Have you tried it?
What type of mains lead did you install in your walls and did you also fit an upgraded fuse and wall outlet?What type of lead did the electric company roll in to your home and how far from the power station do you live?Are you running on wind power, gas or coal?And you keep all mains leads perfectly straight, right?Curls or sharp turns could potentially brake the electrons speed as I'm sure you can imagine and I'm curious how you you managed to do that.
And did you try my suggestion? I will be happy to point you to one or two photos I find to give the best results.
If you can do this then you are a rich man my friend!
Contact any Hifi magazine, or indeed any mains cable manufacturer, and tell them you that can reliably and consistently detect audible differences (in any hifi product of your own choice) caused solely by different Mains power cords under scientifically organised and controlled test conditions.
The cable manufacturer will be so pleased to find someone who can uphold their outrageous claims that you will be able to name your price.
Of course, you may ask yourself, why hasn't anyone else proved they possess such an ability beyond scientific rigour before now, considering the riches on offer!

You should be a reviewer for either Stereophile or Wine Spectator.
This all reminds me of a story I read long ago about a guy who believed AC power was anathema to good sound, any AC in any circuit ever was bad. He'd built an entire setup around car amps and batteries, totally unpolluted by alternating current. Apparently when asked how he charged the batteries he got this crestfallen look and refused to talk about it.
This also goes to the whole thing about people will tend to rate as different two identical stimuli/audio experiences. The human mind lives to find differences whether they're there or not.
Much like homeopathy, this all happens in your head.
The standard powercord cable, should be seen as an antenna. all rfi and emi radiates on it
the same issue with bad quality coax cables.
It is no snake oil.

Sorry mate but that's nonsense - if the 2 metres of mains cord is subject to rfi and emi then so is the 100 or so metres of household wiring it is connected to and then the many miles of cable that connect your house to the generator!
By EU law your appliance needs to meet strict emi susceptibility (and emission) standards.
Finally B&O are, whatever their other faults, not mugs - there is no way on earth they would sell 27K speakers that were compromised by a £2 cable!
An antenna?
Err.. No.This antenna will be shorted by a very low impedance at the speaker end and an EXTREMELY low impedance (microohms at 50Hz) at the power plant end.
Besides, how would this "noise" ever get anywhere inside the speaker?If you choose to see the power cord as a balanced transmission system, the two leads inside the power cord are closely following the same path, they run through the same environment and they will pick up the same "noise".All will be equalled out at both the power plant end and the business end - if anything was ever picked up.
The power supply primary is galvanically separated from anything on the low voltage secondary side - regardless of it having a conventional 50Hz transformer, which practically can't transformer a lot outside the 50Hz range, let alone anything at RF)or a switch-mode power supply, where all incoming voltage is rectified, chopped at a high frequency and then transformed to a lower voltage, rectified again and finally filtered.How on earth should anything - let along a signal as tiny as anything picked up by a 2m lead at microohms impedance - ever get anywhere?How come one type of power cord should be able to pick up this "noise" and another type of cord shouldn't?And why doesn't the rest of the "power cord" (read, the length running to the power plant) pick anything up that should be "corrected"?
Coax cables is a completely different matter. Impedances are a million times greater. Comparing noise picked up by a coax cable to noise picked upby power cords is signal transmission and electronics misunderstood.
Sorry to say this, but it's all an attempt to take peoples money.If you don't like to call it snake oil, let's call it babble, gibberish or gobbledygook.
Keep your money. Stay sane.

Brilliant, Peter.Not that I would ever expect otherwise from you.- Just brilliant!

I made this test on my micro wave oven, even my wife could tell the difference
I've personally found that power cords from Lirpa Labs are by far the best.
