Top 5 Reasons To Choose LDR Passive Preamps

1 – Better Conductor of Music Preamps are, first and foremost, devices for controlling volume. 99%+ of all preamps do this by throttling the audio signal through some type of mechanical device made with resistive materials. Devices like a potentiometer (worst) or stepped attenuator (better). The unfortunate reality is the materials in these devices, together…

What’s Wrong With Audio Volume Control?

What Is Volume Control? Whether you own $10k+ of high end gear or a humble $200 receiver from Best Buy, chances are about 100% that every note of recorded music played through your system is funneled through a volume control device (a.k.a. an attenuator) before it reaches your ears. In the analog signal world volume…

The Evolution of LDR Volume Control

LDR Volume ControlĀ  There’s growing recognition within the community of audio enthusiasts (a.k.a. audiophiles) that LDRs (light dependent resistors) deliver the best sounding volume control technology available today. Over the past 5 years, Tortuga Audio has been leading the charge to evolve and perfect LDR based volume control. In Q2 2017 Tortuga Audio released its…
