Up for sale is my beautiful sounding AUM Acoustics LDR based Passive Hybrid Preamplifier that I purchased from Richard earlier this year. One of just four units like it that he painstakingly built, with the best internal wiring, solder and input jacks on the market. The most refined LDR on the market by far, offering detail, tone and purity like nothing else out there.
- Includes 2A 12VDC external power supply and DC cable/jack
- Remote Volume, Balance and LED brightness controlled with Apple Remote (Included)
- LED Front Panel Display
- Silver/Gold/Platinum HookupWire - As Exotic as it Gets
- Furutech FP-901 RCA Chassis Jacks - the Absolute Best, single pair of inputs and two pairs of outputs. - USB input for software downloads from Tortuga Audio ( standard on all the latest V.2 Tortuga versions)
-LDR Based (using Tortuga Audio pcb’s)
- This unit has been updated with the very latest V.2 board and software from Morten at Tortuga Audio, which has the new autobias circuit for the LDR modules, and has been optimized for use with amps such as my JOB 225 by Goldmund....an amazing match with high-gain amps such as this! It uses the same circuit as Richards newest version, but in the smaller chassis he built, using an external power supply. The following is a description from AUM:
AUM ACOUSTICS VOLUME CONTROL DESCRIPTION I’m selling a hybrid passive preamplifier that takes a major step forward toward achieving the highest level of detail possible while generating a tonality that comes as close to live music as will ever be achieved through recorded music playing through an audio system. Until the introduction of the Aum Acoustics Volume Control, the lack of a statement quality transparent volume control has been the biggest stumbling block and missing item in high-end audio reproduction.
There is absolutely no money to be made building these units. That was never my objective. Rather, I finally achieved a goal I set for myself about a decade ago to design and build the best volume control available anywhere. No more will be built! I simply can’t afford it.
Uses silver/gold/platinum wiring and Furutech FP-901 chassis jacks. This is the absolute best possible LDR based, custom, preamplifier/volume control available today. There is nothing that has been left out and layout, design, and build quality is impecable. These units are both visually and sonically beautiful! They are also built like a tank.
THE LACK OF A STELLAR VOLUME CONTROL IS THE BIGGEST LIMITATION IN HIGH-END AUDIO
No matter how good a power amplifier circuit, it’s biggest limitation is and always has been the restriction imposed by a carbon pot, a stepped attenuator, a digital volume control, or most any other method of adjusting volume. Those standard devices actually harm the audio signal a considerable amount and never allow it to provide the detail and transparency that we all would like to have within our systems.
THE SOLUTION
With the introduction of the Aum Acoustics Version Volume Control unit, this stumbling block has been eliminated and a unique high quality volume control now exists to take any system beyond the limitations of its volume control. You will not find a cleaner, more transparent, more musical, and more detail exposing volume control anywhere (active or passive). Unless there is a substantial impedance mismatch between this volume control and your power amp, you will not find a better volume control solution. Even one of the most difficult to control power amplifiers, the Goldmund JOB225, is perfectly matched when combining it with an Aum Acoustics Volume Control unit. The key to the incredibly superb sound of this unit is a combination of three pairs of Furutech FP-901 RCA chassis jacks (One input and two pairs of outputs), providing an increase in quality over typical rhodium or gold plated cheap brass jacks, and a unique combination of three exotic metal wire types used for connecting all internal components in this unit. Through the inclusion of gold, silver, and platinum wire, a sonic presentation is made available that is unique to the Aum Acoustics volume control unit. Nothing comes close to the positive sound quality presentation of the combination of exotic metals that I use. Nothing! (End Description) . Read more on these units at the AUM website.
