    MY TAKE: Possibly more than any other preamplifier, the Audible Illusions Modulus 3A established itself as a classic in it's own time. The new Modulus 3B elevates that level of performance to a whole new realm. - Galen Carol
     

    Since the product first entered production in 1983, more than 19,000 Modulus preamplifiers have been sold worldwide! Quite an accomplishment, and certainly worthy of the popularity, the M3A stands on its own as a superb audiophile component of the highest caliber. The M3B continues that tradition, building upon the strengths of the legendary M3A.


    The Modulus M3B adds a host of features and performance enhancements over its predecessor, the M3A.
     

    • Relay Switching – signal does not pass through switches resulting in better clarity and definition.
    • Upgraded inter-stage coupling capacitors - All capacitors in the signal path are film and foil or Teflon for better resolution and lower noise.
    • Larger power transformer for the inboard power supply results in improved performance in all areas.
    • Cleaner, more direct signal path results in greater clarity, lower noise and improved resolution.
    • New audio taper on attenuators for more precise matching with a broader range of components.
    • User adjustable gain settings


    The Modulus M3B is a deceptively simple design, employing a single gain stage, class A triode circuit utilizing no cathode followers or buffers to degrade the sound. It is a basic design concept that has remained a focus of the Modulus circuit topology since its inception and is one of the reasons for the sparkling sonic clarity and resolution.


    Inside you'll find a host of superb parts and pieces, along with excellent quality workmanship and great attention to detail. The list of parts includes: Teflon solder mask, OFC circuit board traces, custom film capacitors and custom stepped attenuators using high quality metal film resistors.


    What is it that makes the Modulus M3B such a standout? I'd have to say it is a balance of strengths with few, very few, weaknesses. A strong suit has always been the soundstage, and the M3B competes with most any preamp (almost regardless of price) in this area. It develops an absolutely holographic panorama, that is truly a delight to experience.


    In sum, it is difficult to fault the Modulus 3B on any count. Look for yourself, but I doubt you'll find a preamp with this level of performance, build-quality and reliability at anywhere near the price.


    The MM phono input will accept any cartridge with 1mV of output, or greater. For those using low output moving coil cartridges, optional Gold Phono Boards are available for increased gain. Designed by the legendary John Curl, the ultra-quiet pre-preamp boards give the M3B the ability to handle even very low output MC cartridges with low noise and superb fidelity.


    CUSTOMER COMMENTS:
     

    "I have a Modulus 3A with Gold phono board. The gold phono board is all fet designed by John Curl and is very similar to the sound of the Vendetta phono preamp. The Gold phono board adds about 20db of gain to the signal, then it passes through the M3B tube phono preamp. I use it with a ZU/Denon DL103. The sound is to die for. I also have a Modulus 3B in my main system and the sound of the 3B is light years ahead of the 3A. It is much quieter, has greater bandwidth and the sound is much more relaxed and analog sounding. I am using a Dynavector 20xl low output mc cartridge on this preamp with a Denon AU320 step up transformer. I must say that the gold phono board on my Modulus3A sounds better than using the Denon SUT. The tube phono preamp on both units are very satisfactory. Both phono preamps are very quiet using the Ultra low noise 6h23neb tubes from Audible Illusions. I have to put the preamp volume 3/4 of the way up before I hear even the slightest amount of hiss with my 89db efficient speakers. The L3 is just the line portion of the M3B preamp, it only uses 2 tubes instead of 4. Everything else is the same. If you do not have a turntable, get the L3 instead." - Stereo5, AG Member

    Audible Illusions Trade-In Program

    Did you know you can trade-in your vintage Audible Illusions preamp toward the latest version? You can, and your old preamp is worth a lot more than you might think (and possibly more than you paid for it!).

    If you have an M3A preamp vintage 2000 or later, trade it for a brand new M3B for a difference of just $1995! The M3B retails at $3995, so you’re getting a whopping $2000 for your M3A – that’s a bargain!

    The fine print: Your preamp must be in excellent cosmetic condition and in good working order.
