Further information:

 

This Modulus 3A was fully reconditioned by the manufacturer in 2011. Comes with comprehensive manuals, schematics and original AI box. Current upgraded tubes Russian NOS 6N23P-EB made in Reflektor factory are in very good condition, but I will supply five sonically superior spare tubes - Russian NOS 6N23P made in Voskhod factory. Expected tubes delivery on 2 December.

 

Modulus is well-known for natural sound and outstanding 3D soundstage. Audible Illusions is widely regarded as a reference tube pre-amplifier.  Tape output buffer designed by famous John Curl. 120V – requires step-down  transformer. I am selling on Stereonet Airlink (made in the UK) balanced power supply/transformer (2 in 1) 230V to 120V. Balanced power supply makes noticeable sonic difference - more detailed and vibrant sound.  Audible Illusions designed and crafted in the USA and sold directly by the manufacturer. Current model Modulus 3B cost $5495 USD, plus add some 30% for so called “global” shipping to Australia, insurance, import fees, tax and customs fees (all fees apply to used electronics as well) – total $7143 USD which equals to $9940 AUD.

 

In the Audio Review, there are over 40 users reviews with a average rating of 4.7/ 5 – exceptional.

 

Dick Olsher, The Absolute Sound (2016): “The L3A line preamp [cheaper version without phono section] 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.”

 

The audiophile guru Arthur Salvatore noted in his list of reference components: "[Modulus] 3 may still be the finest preamplifier with phono available today for the money".

 

Georgehifi, Australian designer of renown “Lightspeed Attenuator”, noted: “The AI 3A is one of the best pre’s I’ve heard”.

I definitely have seen reference to John Curl MC in Modulus 3A somewhere.  Maybe Modulus 3A has different versions of MCs?  Or different location on the board? What is location of MC board in the photo? All I know that this model has outstanding and highly appraised everywhere phono stage with two dedicated tubes. Anyway, thank you for your very valuable input - I removed the reference to John Curl MC.

Yes as the poster stated this Unit does not have the  Curl Gold LOMC Boards-at the time a $5/600 USD Extra. However you are correct

in noting Johns involvement elsewhere --namely the Tape output buffer is his work.

      Item Condition: Used Shipping Options: Pickup available but audition is not available. Suburb or Town: Hills District State: NSW Payment Method: Bank Transfer or Paypal (add 4%) Reason for selling: Not in use
      Condition: 5/10. Need some TLC.

      These had suffered the infamous sweating mid range driver syndrome which i've since replaced. The tweeters are ok. The bass drivers i assume are also ok. I can't remove the grill so can't check unfortunately. The sweaty drivers had corroded one of the spades at the end of the internal wiring for the one of the towers. I didn't bother cleaning the corrosion properly back then and unfortunately it has corroded the replacement driver's t-pin for the spade to connect to. The other driver is fine corrosion wise. However both speakers need new internal wiring as both are showing corrosion. I've also snapped the plastic bits holding the other t-pins connecting the spades on the other mid range driver when i opened it up, doh. Both speakers had been working before i opened them up. It seems there is no longer a connection for the tower with the corroded spade after i had disconnected it from the mid range driver and as a result it's no longer working, another doh. You don't need new drivers to bring these babies back to top working condition. Just some new spades, wires and some macgyver handiness should do the trick.

      Crossover looks ok. I only opened up the tower with the corroded spade. Since the corrosion is not as severe on the other tower, i assume the crossover on that side is ok as well.

      There are some chips on the exterior as shown in the photos. There are hairline scratches as well but hard to see being it in Ash Black finish. Overall the grills are in good shape. There's little fraying on the top left corner on the left tower.

      No audition, pickup only and will be no contact. I'll have them in front of my door for you to collect at a suitable time. For more trading feedback, my ebay is https://www.ebay.com.au/usr/swoo-c

      I've uploaded a test video for you guys to hear. The right one is the one with the corroded spade and t-pin. Any other questions or request, let me know :).

       Suffice to say:
      - it sounds like a powerful SET amplifier
      - lots of 2nd order harmonics
      - very smooth and lots of resolution - good power
      - heavy and well built
      - Jeff Day loves it!
       
      A Japanese legend worked on this design.  I bought some mica caps off him as well.  This is a well known mod (again, Google will help).  It radically improved sound as I recall.  These will come with the amplifier.
       
       
       
      i did then also buy Mica caps which were $320 AUD.
       
      i have original box and manual etc.  there is no remote control.  
       
      i can send via pack n send or even deliver it if you are anywhere close.  
       
       There is a slight dent on righthand side.  I can't say i ever much notice it but have pointed it out to be clear. it is right hand side front.  it is not significant hence it being hard to see in photos.
