michaelwjones Posted August 25, 2021 Share Posted August 25, 2021 The closet cleaning continues... This pre is dead silent and adds, to my ears, no coloration whatsoever. That can be good or bad depending on your ears & system. Its perfect for Klipsch speakers as there is seldom an issue with the output voltage from our front ends to drive speakers without the need of additional gain. I never found a DAC or CD that could not drive my amps. The Tortuga LDRx is an audiophile grade passive preamp which comes standard with Cardas GRFA-L RCA jacks: 3 inputs and dual (parallel) outputs. Internal wiring is high quality Milspec teflon coated 26AWG silver coated copper wire. Simple 7-button Apple Remote provides remote control, along with a rotary encoder with integral push-button located on the front panel. Volume level and status information are provided via a pair of digital displays that are invisible when the unit is off. Specifications Preamplifier Type: Passive unity gain without buffer | attenuation via light dependent resistors (LDRs) in an LPad configuration Attenuation Range: –60 dB to 0 dB in a 70 step attenuation schedule Nominal Input Impedance: 20k ohms Control System: Software based (updateable) 8 bit digital microcontroller driving 12 bit digital-to-analog volume control Software : Updateable via download from website and upload via USB cable from PC Auto Calibration: User enabled/disabled self-contained auto calibration of LDRs to correct for drift/aging Display: Dual numerical displays (blue) providing volume and status information https://tortugaaudio.com/products/archive/ldrx-passive-preamp/ $700 plus insurance and shipping to you. The unit has no issues either cosmetically or sonically. Includes factory packing, power cable, Apple remote & photocopy of operating instructions. 1 Quote Link to comment Share on other sites More sharing options...
Shakeydeal Posted August 25, 2021 Share Posted August 25, 2021 This is indeed a very good preamp. I have had two different ones in the past. GLWS Shakey 1 Quote Link to comment Share on other sites More sharing options...
