When Ron Brenay of NewRecordDay.com visited our room at RMAF14 he discovered he really didn’t want to leave. Why? Because he was having such a good time listening to music on our system. He was sufficiently impressed that he asked if I’d do a video interview and although I’m camera shy to a fault I…

What Is This Notice About? Since initial release of the ldr3x.V2 board we’ve been actively evaluating how auto-calibration is set up on the V2 board with the help of feedback from our V2 customers and even input from prospective customers. As a result of this work, we are making some changes to auto-calibration. Also, we…
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…
All newly built Tortuga Audio LDRx preamps that ship on or after March 1, 2014 will incorporate an upgraded internal power supply design resulting in improved audio quality. The improved sound quality manifests as a darker, quieter background between notes and a corresponding increased expression of detail. Since the LDRx sound is clear and detailed…

Better LDR Passive Preamp Sound Tortuga Audio has developed an improved software based LDR control algorithm that greatly improves on our already highly regarded LDRx Passive Preamps. Key aspects of this new “HiZ” (high impedance) control algorithm include: Substantially increased input impedance with a nominal 10k ohm impedance floor Improved sound including better dynamics, musicality…
As a follow-up to our original post below, we wanted to share some unsolicited feedback from a recent LDR3x customer. Note that the LDR3x board is our second generation LDR preamp board design that builds on the success of the original LDR1/LDR6 passive preamps. A pair of LDR3x boards will be the twin beating hearts…
I’m pleased to announce that 6moons.com has published a very favorable review of our LDR6 passive preamp. It’s quite an extensive review including background on its development and an in depth description on what goes into the building of each of our LDR preamps. My favorite statement by the reviewer: The Tortuga Audio preamp equaled…
The best part of being in the high value audio design and manufacturing business is working with customers who have more interesting ideas than you do. A recent example is when a full professor at Harvard University contacted us and asked if we could provide a pair of mono passive preamplifiers for his home audio…
As we work to expand our line of next generation preamp products built around light dependent resistors (LDRs), we also plan to soon introduce an LDR based preamp controller board, and related products, for the Do It Yourself (DIY) audio community. As we’ve previously announced, Tortuga Audio is actively developing a balanced version of its…
The debate over passive vs. active preamps mushes on within the audio community with the prevailing wisdom being that an active preamp is better than any/all passive preamps. Is this really true? As with so many things in life the answer is….it depends.

Our First Customer Reivew One of our recent customers shared his initial impressions of our LDR1 Passive Preamplifier. Here’s an unedited reprint of that review. I’ve had my LDR1 for a week so it’s time to write my initial impressions. Let me state up front that the LDR1 is the most pure, neutral, transparent, noise-free…
Without new blood and reinvention, the audiophile industry will die out in the next 5-10 years. And most existing industry players either don’t get this or are dancing the night away on the Titanic waiting for the inevitable iceberg. That’s the overarching theme of Jerry Del Colliano’s provocative article in hometheaterreview.com in the wake of the…
The Perfect Preamplifier If you read enough articles on high-end audio you eventually encounter the definition of a perfect preamp: no preamp at all. Just a short wire between the line source and the amplifier. Purity of audio signal maintained unsullied by intervening gear. All fine and good provided you live alone, have few neighbors…
