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 with their mechanical interface points, alter the audio signal in ways that are not […]

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 control means throttling back the voltage level of the audio signal prior to reaching

LDR Volume Control  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 fourth generation LDR technology which is included in all of our current passive preamp

Saying Yes To Light Dependent Resistors

Why Light Dependent Resistors? Why did we design our Passive Preamps with light dependent resistors (LDRs)? Because they sound better than all other options. Better than any potentiometer (“pot”), better than any stepped attenuator, and better even than transformer based volume controls. LDRs have excellent sonic quality and make it possible to have no mechanical components (relays, switches, potentiometers) in the signal path.  They are the ultimate transparent volume
