Some time ago it was asked on our Yahoo group about some sample music files
where we tested the transmitted signal from a LCD unit to a high
performance Pioneer F-99X stereo tuner. Unfortunately thay don't make
tuners that good anymore. The tuner's circuitry was calibrated in our
Engineering lab for optimal performance.
The files are again obtainable from our site: (each file 5MB)

This provides samples for various types of music
In each case there are 2 samples of the same music (one direct
recorded from the CD with the highs cut to be equal to the 15kHz
limit of the transmitter). The other sample was recorded directly
from the Pioneer tuner receiver's line out. This was transmitted over
a distance of about 50'
This should give a good idea of the sound performance with a top
grade tuner.
Each file was chopped/saved to be the exact size to make it
impossible to see any difference by file size.

"If the real LCD sounds this good, it is God's gift. All the ipod FM
transmitters found in stores are garbage, no compare at all. How could
they claim to have 35dB stereo separation?! Or the actual separation
of LCD is much higher than 35dB?"

"This thing is amazing. I have been listening to it ever since I got it
and love it every minute. Deeply disappointed with all the iPod
transmitters.
I spent quite some time studying on LCD before I pulled the trig,
because it uses the same BH1414K chip that's used in all the garbage
iPod transmitter. It was hard for me to believe how could the same
chip sound like night and day. For $200, I could not buy one from a
local store to try and return. Not only have all my doubts gone now (I
still have no idea how EDM did it), it is also far better than I could
ever expect.
It is lucky to still have someone to work on such master art pieces.
Life cannot be any better, thank you, EDM. Long live FM!"
