We are very, very proud of the new AXIOM II after more than 15 years of producing the amazing Axiom I.

There are too many positive changes to mention regarding the Axiom II. The opportunity to both make the unit a million times more attractive as well as give ourselves enough real estate (room!) to utilize it with many options for both single chassis XLR versions as well as multi-input versions was the most obvious choice. The aesthetics and increased flexibility have improved 400%+! 

Please check out our latest review with here....  Also, the major Positive Feedback review from 2012! &  Latest review right here....

 This unit is made in America! 90% of most "new" passives are from China/Taiwan, etc. The Luminous Audio axiom is a major twist on the "standard" passive preamp. 95% of all commercially available passive preamps "allow" your precious audio signal to flow through its volume control. This is the most difficult area for your signal to pass w/o distortion and loss of clarity, etc. Our circuit employs one very high-quality 1% metal film fixed resistor in series with your power amp. The volume is adjusted by shunting your amp’s input to ground via our volume control to ground and allowing the signal to flow into the amp by a "valve like" circuit. The clarity and detail offered by this type of circuit truly blows away all other passive solutions next to a 100% 1% resistor-based control (see our Walker-mod version). The new ALPS pots used in the new version have continuous smooth rotation in lieu of the steps on the older one. This provides considerably more control over the original Axiom. Part of what makes our passive so good is the lack of inputs. PLEASE NOTE......The standard Axiom unit has one pair of inputs and one pair of outputs. This is a very important part of why the Axiom destroys most any other preamp on the market. Most critical listening is done with cd’s anyway, so why not shoot for the ultimate in clarity. The AXIOM is shipped with a Holco resistor unless buyer is willing to upgrade to the caddocks for $25 more. The CADDOCK TF020 resistors are the best in this circuit. I promise this preamp will outperform anything under $3,000 or your $ back!!!! I will email the buyer with a brief questionnaire about his/her system so we can make sure the gain is calibrated for him/her. The unit uses high-quality custom gold RCA inputs,Luminous 4/9’s pure silver wire and a smooth Alps precision pot. We are now also now providing a much more substantial and beautiful chassis than we have in the past 13 years. The most exciting thing about the new chassis (apart from its now gorgeous looks) is the fact that we have designed it with enough real estate to have many options never before available in one chassis with the original axiom. Gone is the need for two chassis’ if you wanted an XLR version or a multi-in unit. Now both are available with a single chassis Axiom II as well as Dual outputs for vertical bi-amping, sub woofers, etc. It is important to note that the only difference in the Axiom and the Axiom II is the new and improved chassis. It does offer greater shielding capability so perhaps in areas of hi RF/EMF the new version would be desirable above the original. See for examples of our cables in addition to more info on the Axiom II. You can read a ton of reviews on audio asylum, etc. and again, our website has just been updated with MANY testimonials for the AXIOM. Just released! The multi-input version and the XLR version is $375 as a single chassis unit now.

New news! NOW OFFERING PRE BURNED-IN AXIOMS for a $35 fee!!!! Have your AXIOM sound smooth and perfect right out of the box for a 3 day wait and $35. Bill has developed a means of quickly "cooking" your Axiom in a 3 day period to allow better sonics upon arrival. Just mention it to us when you get back upon the winning bid. Please take a moment and see all of the killer testimonials recently added to our website at

See for examples of our cables in addition to more info on the Axiom. You can read a ton of reviews on audio asylum and again, our website has just been updated with MANY testimonials for the AXIOM. Just released! ***Please note*** The response to the axiom has become overwhelming lately. I really need to rely on e-mail for communication as much as possible. May I humbly request calling us ONLY if you do not have access to e-mail. I promise I can answer all questions via e-mail and more efficiently as I can do so late in the evenings, etc. I have become very difficult to reach during the day and I apologize. Have more than just a cd player....well, after years of customer’s recommendations/requests, we have decided to offer a solution for those with multiple inputs. For those who are used to the awesome “switch less” version we are still incorporating a direct input on the new units. Two inputs are offered as well as the direct input. However, the new Axiom with multiple inputs may or may not offer three inputs in all systems. Dependent upon the output impedance of your direct source when turned off or on, you may be forced to unplug the direct device when not in use. i.e., the output impedance of your CD player will be in parallel with the other source you have chosen. If the CD player is turned off, it may go to infinity (or still a very high/desirable value) or it may literally short the outputs therefore not allowing any sound on any input. Worse case scenario the customer will still have at least two inputs from which to choose and the “mechanically switchable” direct input. This will require testing via ohmmeter or just simple experimentation. If the direct source is making an effect, it will be very noticeable. Again, this listing is for the standard single input Axiom w/ RCA’s but additional options are available. The most typical upgrade is the Signature (caddock resistor) version for the additional $25. Dual outs, XLR version, Multi-inputs, etc. available upon request. See pictures below! A SAMPLING OF OUR INCREDIBLE TESTIMONIALS (Many more can be found on; Hi Tim, The Axiom sounds just as I had expected, which is to say, amazing! Music unveiled like never before, with very tight bass, transparent mids, and highs without limit. String bass and cymbals have far more detail and variety than I had ever realized. Overall, the sound is what I would call "modern", clean and accurate. When I think about these big 25 pound boxes (including my Accuphase) that we use to "preamplify" the signal, it seems rather overkill, especially if you only have one or two sources. Your Axiom is a true wonder. Thanks again, and be well, Robert Got it today! I am slackjawed... amazed! Opened up the soundstage and defines the individual instruments... SUPERB PRODUCT! Thanks!!! Tim, Axiom arrived today. Plugged it into $6000 worth of Naim NAP 135 monoblocks ( Naim, incidentally advise against using any form of passive preamp ) And it is really stunning. Quiet quiesant background ( no hum or hiss of any form ) Detailed and as far as I can hear ... excellent. I am impressed, well done. cheers dave Hello Tim, I received the preamp in good condition on Friday and hooked it up that evening. Wow !! What a sound, it was marvelous to hear I could further increase everything one notch !! Definition, space, information, soundstage, transients, zero noise and especially more precision everywhere... How can you beat my "brand X" ??? I am VERY happy ! It seems that the Axiom lets more energy of medium to high frequencies go through. Very well done ! Thanks again for the unexpected satisfaction ;-)) Olivier Tim, The Axiom is AMAZING!!!...Thanks! Bob Tim, I received the unit yesterday and just hooked it up. It is a tremendous value! (but I guess that is no news to you!) It sounds even better since my preamp has been out for repairs for 6 weeks. Thanks Ron Hi Tim, ...The product is fabulous and I will be leaving positive feedback on Audioreview if your product is listed there. I will definitely be spreading the word around here. Congratulations on a simple but great design. The Axiom is truly transparent and I have never heard my system sound so natural. You can quote me on this! I will never go back to active preamps. best regards Steve Hi Tim, I received the Axiom Passive Preamp today in perfect condition. The Axiom sounds better than I expected. The bass is tight, mids are transparent and highs are clear without becoming abrasive. I guess the word I would use to define the sound using the Axiom would be “PURE”. Best audio purchase I’ve made in a long while. Thanks again, Tom
