Music First Audio Passive Magnetic Preamplifiers?

The Lighter Note is a circuit parts only kit, you still have do all the chassis, rca and ancillaries etc yourself. Uriah did ask me if he could sell matched "pairs" of ldr's on DIYAudio for members and I said yes to that, I do go one further and do matched "quads sets" in the production Lightspeed Attenuator, it gives a better logarithmic feel to the volume control but is exponentially harder and costlier to match up. As for the powersupply it makes no difference, as a battery, as you know is the best form of dc power one can do for the led's and it is no better that the double regulated power supply I give the production Lightspeed Attenuator.

Yes the "Myth" this is a blatant rip-off of my Lightspeed Attenuator design, how can one charge $1700 + $300 shipping for just a bit more glitz and a remote is beyond me. I have been asked many times to do a remote model and I figured it to still be under $1K, some people reel back at my $450 shipped price tag, so it will probably never eventuate.

Also if you PM me your email address I'll send you a PDF broucher.

Hi Paul, your Lightspeed Attenuator chassis is fully shielded alloy, it gets it's RF sink earth via the interconnects. Vibration doesn't come into it as there is nothing to get vibrated as it's passive, even the active led's are immune as they are gas element, no filaments. The feet I attach are soft silicon/sorbethane compound anyway just in case. Glad to see you love as much as others do. It would also be unsuccessful to be transplanted within pre's or poweramp environments as the temperature is too erratic within these chassis for the Lightspeed components to behave stably, I even physically couple all the ldr's together after precise matching and then pot them in hard wax to keep everything stable in the your production one.

I first did the Lightspeed Attenuator back in 1975 but the LDR's were horrendous to keep calibrated I thought about patenting it but with zero reliability what was the use, it still sounded to everyone as the most transparent/dynamic pre they ever heard. I shelved the idea till I hoped LDR's became more reliable.
Melos then tried it in the 90's their kilo's $$$buck SHA-Gold reference all these failed also probably what sent them broke. Also Haffler had a stab at it around the same time. And now Dartzeel don't get me started on that one.
It wasn't till the early 2000's that I finally found reliable LDR's that would stay matched. This is the story why now I cannot patent the idea I should have done it back in 1975. But I can stop others from trying to patent it for them selves.
As for making it sound better, simply, no, what I make is a good as it gets, extra inputs sound worse because of the switching contacts, remotes do nothing for the sound, my philosophy with it is KISS and keep it affordable.I have even run it off pure battery power, we say there is a very slight difference but no one can tell what the difference is, even golden ears Sam Tellig
