We’ve taken a different path to making a better sounding preamp
Our preamps don’t use conventional volume control technology.
No potentiometers (“pots”)
No stepped attenuators (switched resistors)
Why not? Because they don’t deliver the best audio performance.
Our preamps use “light dependent (photo)resistors” or LDRs. Photoresistors are not new technology but they pose unique and difficult challenges to audio engineers. That is why preamps typically use conventional volume control hardware. We took on those challenges and solved them. Why? Because we wanted to design a better sounding preamp. So we did.
Your search for the perfect preamp for your system could be over
A Tortuga Audio preamp owners sent us these unsolicited comments….
“What an experience! Truly the best sound I’ve ever heard in my system. A layer of “mush” has disappeared…. More details and less harshness, especially in mid-upper-high range… It is absolutely marvellous at low levels….it’s all in perfect balance from 1 through 99 with a beautiful room experience, width and depth in the music.”
“I am a classical musician, aged 68. In the audio hobby maybe around 30 years. Have heard no end of preamps and passives. Certainly 100s, maybe more. Yours is the best sounding – the closest to the sound of music.”
