Recent Customer Quote

“Your newsletter prompted me to say a big belated “thank you” for making the very best preamp I have ever used. From tube to solid state, vintage Western Electric and Marantz to modern Cello and Krell, nothing comes close. My downsized system is unbelievably dynamic yet completely natural and without any hint of strain, harmonically accurate and rich especially with “challenging” brass and woodwind instruments, always happy to play back what it receives. My system has NEVER felt (and sounded) this good.” – Tortuga Audio customer

LDR3x.V2.1 Passive Preamp Controller

The V2.1 is an updated version of  our popular V2 model and as such is less about new features and more about refining the hardware design resulting in a more robust controller with the potential for improved performance. We were able to make these changes without raising the price ensuring that the LDR3x remains one of the best DIY values in a audiophile grade attenuator available today!

New aspects of the V2.1 that differ from the V2 include:

  • No piggyback auto-calibration board
  • 6 layer PCB board
  • Separate digital & analog power
  • Multiple linear regulators 
  • Bipolar voltage
  • Socketed Op Amps
  • No relays in audio signal path
  • All on board power fully regulated
  • Accepts broader range of  supply voltage
  • Slightly longer board but same mounting hole dimensions

Pre-order Pricing Special: The LDR3x.V2.1 is available for pre-order for $199 between now and Jan 5th, 2015 at which time it will be released and pricing will revert to the regular $259. More info on the LDR3x.V2.1 can be found here.
