Greetings. My name is Nicolas BOYER and I'm the founder of Lebel Audio, 2013, located in south of France, near Toulouse.
www.lebel-audio.comFor now, I built products used mainly on movies production sound in Europe. The PWL is an analog preamps and mic powering specialized for location sound.
I focus on weight, size, consumption and noise. I have always been fascinated on old tech, transformers are heavy and tubes are big, fragiles, power hungry and noisy compared to opamps.
For 5V & 1mA, some opamps cand do better than 5nV/sqr(Hz) noise and many designs never use inductors.
I came to Audio Circle mainly because of tubes, this forum is a good source of inspiration.
Thanks to all.
Nicolas
