Impedance Mismatch: A.I. M3A, Krell KSA100
Nolanh, AI Recommends, when the M3a is connected to an amplifier with a low input impedance, keeping the interconnect cable shorter than 10 feet. Typically, the M3a has 5uf coupling caps so you should encounter no problem. Regards, AI Technical 
Impedance Mismatch: A.I. M3A, Krell KSA100
Should be no problem providing you don't run very long, high capacitance interconnect cables. We know of many Krell owners who also own an M3A with excellent results. Regards, AI Technical 
Audible illusions Modulus 3A or Klyne 6L
Yes I've read your 10 posts and from the 1st, in which you make the statement that "unfortunately the AI is known to be a tube eater". It's my belief that you are attempting to convince readers that there is a technical problem with our design. I ... 
Audible illusions Modulus 3A or Klyne 6L
It's unfortunate you continue to imply there's is a design flaw in our circuit design by reguritating old comments that our preamps are "hard on tubes". Considering the thousands of preamps we have produced over the past 25 years I'm aware of the ... 
Audible illusions Modulus 3A or Klyne 6L
AI Modulus Preamps Are Not Hard On Tubes... To date we have mfg.many thousands of these units and, to the best of our knowledge, premature tube failure has not been a problem. The problem is some "tube rollers" continue to substitute old-style 6DJ... 
Audible Illusions Modulus 3 and Rogue M-120 Okay?
Morgandogge, AI preamps have reputation for being very quite. Suggest you tell the owner to buy a good set of tubes.

Audible illusion L1 potentiometer upgrades
For the mono pots the L1 uses 2-50k-conductive plastic audio taper, custom mfg. for us by Bourns. The stereo pot is a Bourns 20k conductive plastic. If you bypass the mono pots a TKD 50k stepped attenuator would improve performance. Regards, Jerry...

New Quicksilver New Audible Illusions Preamps
Yes, Audible Illusions has upgraded the M3A to the 3B. It's the first major revision to the design in almost 10 years. However there won't be a formal announcement until we have completed the initial production run. Sonically the difference betwee... 
Audible illusion L1
Pepericoz, We mfg.the L1 from 1994-2003 and made no updates to the design during this period. However, the 5mF/300v polypropelyne caps could be updated to newer versions. Also, replace two of the four HVB+ 100mf/400v, radial-lead,Panasonic electro... 
Audible illusion L1
The 4 dip switches modify sonics of the preamplifier's line stage. Once the preamp has been broken in we recommend that they be switched to the OFF position. Regards, Jerry/AI 
Excessive "hiss noise" from Audible Illusions 3A
Arni, I doubt the 230-120v converter is causing your hiss problem. Most likely your audio systems sensitivity is suspect and the preamp needs a new set of low-noise tubes. Be advised the phono signal is routed through the preamps line stage and I ...

Tubes for Audible Illusions Modulus 3A?
Docknow, Judging from your message, I see nothing wrong with disconnecting AC from your M3a/audio system during long periods. I highly reccommend this practice during lightning storms. Your M3a uses apx 45 volts which won't make much of a dent in ...
