Up for sale is a MINT condition gently used Audible Illusions Modulus L3A Preamplifier which is in the original double box. This unit was manufactured and shipped to me mid February 2017 and has a current retail price of $4695, so this is a great deal! This L3A has a black faceplate and black chassis with GOLD lettering and hardware and of course being an L3A, it has a REMOTE CONTROL! The knobs are back lit with beautiful blue lighting to enhance the ease of use in dark environments, as well as for a true touch of class. I used this preamp in my personal system and it sounded terrific but I decided to purchase a new Audible Illusions M3B with John Curl gold board moving coil phono stage to replace it as I wanted to get back into LP listening. This unit has approximately 80 hours on it and therefore is barely broken in and like new with remote, umbilical cord attached power supply with detachable power cord, original double box, Allen wrenches and extra bolt, warranty card, owner’s manual and other paperwork which comprise all original factory accessories included with the unit.
I much prefer local cash sale so purchaser can inspect and witness full function of the unit for themselves in person after they pay for it as I do not accept returns. For out of area buyers: USPS Money Order payment is required in advance of any shipping. In addition, positively no paypal, checks, wires or other means of payment accepted, so please do not ask.
If interested, please send me your full name, TELEPHONE NUMBER (no replies without it!), location and E-mail address and I will reply to you promptly. You WILL NOT receive a reply without this requested information supplied to me due to spammers and scammers. I will remove this listing as soon as it is sold, therefore messages/questions like "do you still have it" will be ignored and deleted. Thank you for your understanding and interest in advance!
You can find many positive reviews on the internet for this unit. It is truly one of the best preamps available at any price! One reviewer’s example is listed here from Dick Olsher of The Absolute Sound for your convenience:
“The L3A line preamp distills the best attributes of modern tube sound: swift transients, a detailed presentation, and natural yet non-euphonic textures. It is its insistence on the sonic truth that defines it as a true reference line preamp. The L3A’s ability to retrieve the music’s rhythmic drive and drama make it one of the most sonically persuasive line preamps on the market and one of the best I’ve auditioned over the years at any price. If your goal is to conjure up audible illusions on a grand scale, this is your preamp!”
Please see the following details from Audible Illusions website to illustrate further information:
“Many audiophiles remember how the introduction of the original Modulus preamplifier excited the audio industry. For the first time a full-function, reliable vacuum tube preamp with true high-end sound was available at an affordable price. It’s rare for a company to capture ones imagination and loyalty even once in such a manner. With the debut of the new L3A Line Stage the Legend Continues.
As many audiophiles migrated to CD and digital media for their main source we began producing our Modulus line stage series. These preamps were specifically designed to optimize digital playback and other line-level equipment. While the L3A retains the physical characteristics of its predecessors, it‘s not a rehashing of old ideas. The preamp is on the leading edge of audio technology. The L3A makes elegant use of engineering approaches to circuit board design that improves signal flow and reduce interference and vibration. A Class A, zero feedback, single-ended design built on the proven tube design philosophy that “simpler is better”. Additional improvements include dedicated relay signal switching and Teflon coupling capacitors which result in outstanding resolution. The L3A also features a dedicated external power supply which isolates AC fields from the main chassis and prohibits common-mode noise from interfering with the musical waveform.
In terms of features the L3A is an audio control center second to none. It has inputs and switching designed for CD, DVD, Tuner, External Phono Stage, Video, Aux and Tape. Volume and Muting functions are operated from the front panel or with Remote Control. The L-R Balance Controls are Precision Stepped Attenuators.
For Home Theater use the L3A includes complete input and output switching facilities for Surround Sound Processors. Another feature incorporates special active buffer circuitry for optimum matching of components which prevents signal degradation and impedance mismatches.
As with the previous Modulus preamplifiers, the L3A is next step in the evolution of our famous single-ended designs. The Heart of Fine Audio and Video Systems for Years to Come.
Control Functions: Master Stereo Volume, L&R Stepped Attenuator Balance Controls, Source-Tape, External S/S Processor, Mute and Power. Remote selects Stereo Volume Up-Down, Muting.Output Selection:Main (2) Tape, External S/S Processor.
L3A TECHNICAL FEATURES
• Circuit Design is Pure Class-A, Single-Ended Triode, Zero Feedback, Dual-Mono.
• Audio Circuit has no Cathode Followers or Buffers.
• To prevent unwanted AC-induced distortions, the L3 features an External Power Supply housing three separate supplies and a large-shielded, custom-wound transformer.
• In the main chassis, four-separate, fully-regulated FET power supplies drive the audio circuitry in addition to separate filament supplies.
• Automatic-timed muting with Tri-Color LED indicator.
• Low-light Illumination for Selector Switch and Master Volume Control Knobs.
