How Many Audiophiles Does It Take to Change a Lightbulb?

Only one.

But ten to discuss whether you need a 60W or a 100W bulb.

Ten more to discuss the relative merits of screw-in vs. bayonet fixture.

Ten more to discuss the relative merits of LED and halogen.

None! Then they can sit in the dark and conclude their blind tests are valid...

I could get into blind testing light bulbs....it has a sort of Irish logic to it.

I'm not paying £££s for something I can DIY.  So first I sourced Russian made lamp bases.    Then after extensive research, I developed my own braided filaments using .9999999 copper and tungsten and a material I prefer not to disclose (I'm filing for a patent) in what I call a Hyper Light Braid.  The braid creates an optimal distribution of photons across the visible spectrum--though as an older male I do have some upper-frequency roll off and don't see deep purple as well as young folks.  My wife and kids can though.  Colour temperature is controlled by the ratio of copper to tungsten to my material X.  

Next is the critical issue of bulb type.  While the conventional white frosted bulbs are more pleasing they obviously both filter and distort the source.  So clear bulbs.  But not glass.  Currently, I'm using crystal specifically Waterford globes. Swarovski is for rich poseurs.   I use argon to fill the globe at 2 atmospheres.  I use a regulated linear power supply, of course, rewired with Cardas wire and Wattgate plugs.  

The resulting light stage is very broad and deep.  I can see the precise location of every component in my big hifi.  Shadows are very carefully cast with little excess penumbra due to the single point source nature that the braid creates.  The light is very revealing of surface imperfections in the panel faces as well as dust on the turntable plinth.  But the truth is more important than beauty.

I don't replace mine. That way I don't have to look at the aesthetic nightmare that my setup is at the moment.

And 30 million when somebody points out the applicable EU regulations and a Brexit discussion argument fight breaks out.

Q: How many subjectivists does it take to change a lightbulb?

A: It's never been accurately measured.

I just replaced two bulbs that weren't working before. It's like a veil has been lifted and even my wife could tell the difference. The inky blacks have definitely been changed.

A: It doesn't matter how many of us it takes to change a lightbulb - and if we say it has been changed, you'll just have to take our word for it, otherwise we'll throw our toys out of the pram and accuse you of bullying and using long technical words like "light" and "bulb". OK...? 

 

Fixt... :whistle:

That’s just a filament of your imagination.

I've been undertaking blind cable tests on my light bulbs, I'm still not sure if multicore is better than single core and I'm trying some silver core next for the ultimate in white/ black contrast
