In playing with the Alexandrite. I am building a flashing LED circuit.
Very simple: resistor inline with the LED and then hooked up to a battery (I am awaiting some AC power supplies).
The curious thing I once I turn the circuit on even without any crystals nearby I hear an improvement in my system. Background becomes quieter and more fine detail becomes evident. Dynamics improve and sound from top through bottom becomes "tighter" for lack of a better word.
The sonic change is not staggering, but noticeable. I am actively pursuing the alexandrite front which provides, at least my system, greater sonic improvement, but I thought I'd mention this for others to possibly pursue
You can pick up Flashing LED very cheaply on Ebay. I use ultra bright 2Hz models white light.
For naysayers, and you know who you are, please don't bother. but I find it is an interesting effect.
As I previously mentioned it may be the basis for the Stein Harmonizers, but a hell of a lot cheaper, so far.
Follow Ups:
Inside or outside the component?
If outside what is the proximity?
Is a single pair of diodes sufficient for one or several components?
I am using both the battery ground and charcoal to great effect :)
Thanks,

I use the diodes in pairs. Anywhere in tbe listening room makes a difference. but i like to place them close to indicator LEDs in components. You can often solder them in parallel to existing LEDs. If your component has a low voltage PS ,you can piggy back tbe flashing u.units off of it. On mYDAC it increases bass and actually lowers the noise floor.
Thanks a lot.
Will report as soon as I get the white ones.
Please start a new thread or contact me directly
thanks

How many volts battery?
How many ohms resistor?
Are you seeing the strobing of the LED, or is it hidden from view?
Have you tried a non-flashing LED for comparison?
I bought my flashing LEDS from lighthouse LEDS on Ebay they have a very convenient chart for resistors to limit current at different voltages. For 9 volt battery about 300 ohms for 12 volt (AC power supply) about 470 ohms.
I place the flashing LED in a wooden box ( my plastic ABS project boxes sound horrible). I find the flashing a bit annoying.
For alexandrite, the non flashing LEDS are not quite as effective
YMMV and FWIW
Can you elaborate on what the purpose of the crystal is for and what the flashing LED is for?
Cheers
Anthony
