If you’re looking for high performance preamp we don’t believe you’ll find many preamps that sound better than the LDR3000T. Don’t take our word for it. Go ahead, buy one, and  you’ll have 30 days to try it at home in your own system. If you’re not happy with the LDR3000T you can return it within 30 days for a 100% refund less your cost for return shipping.

The dual USB port is ideal for building a DIY balanced preamp with a pair of Tortuga Audio’s V25 Preamp Controller. The dual USB port uses a single XLR-A panel cutout to provide separate USB connections to each of the V25 boards for firmware updates. Connection between the dual USB port and each V25 board is via a 12-inch 5-pin cable. Two (2) such cables are included with the port module.

Note: This preamp model is no longer available and has been replaced by the LDR3000P.V25 High Performance Passive Preamp

The LDRxB.V25 is a high performance balanced passive preamp that combines Tortuga Audio’s advanced LDR (light dependent resistor) attenuation technology with elegant contemporary styling designed to satisfy the most demanding audio enthusiast. The LDRxB accommodates up to 3 balanced XLR inputs and a single unbalanced RCA input. Dual (parallel) balanced XLR outputs are provided along with  a single RCA output.

The LDRxB.V25 delivers clear, articulate and honest sound with a dead quiet background together with satisfying dynamics and surprisingly powerful bass.

The solid state LDR300.V25 has been discontinued as part of our renewed strategic focus on our passive preamps and related tube based buffers. 

The LDR300.V25 Buffered Preamp is a remote controlled, singled-ended, solid state active preamplifier that combines Tortuga Audio’s popular LDR (photoresistor) attenuation technology together with a robust JFET current amplifier (output buffer) to deliver high performance audio that will appeal to the discriminating audio enthusiast.

The LDR300 is a unity gain preamp without the gain stage (amplification) that typically colors, clouds and adds noise to the signal path of most active preamps. The LDR300 embodies the “less is more” design philosophy.

Enthusiasts who value a dead quiet preamp with a deep dark background between the notes, exceptional transparency, and pleasing dynamics, will find the LDR300 to be a very satisfying preamp rivaling many high end peamps at a fraction of the cost. And it comes with a simple remote control and graphic display feedback so you can relax and enjoy your music in comfort from your favorite listening spot.

Comes equipped with a remote, external power supply,  3 inputs and 2 (parallel) outputs using high quality silver/rhodium plating over solid brass Cardas jacks.
