Audible Illusions Modulus 3A noise

I have owned 3 AI tube preamps since 1994.   I had the original Modulus 3, the 3A, and the 3B. None of them gave me tube noise or hiss.  The key is to get your tubes directly from AI,  or find matched sets of 6H23NEB tubes for the preamp, they are very rugged and quiet   You may find them at the Tube Store or from Upscale   Your noise will disappear like magic, poof  

@carlsbad2 , the preamps are not mass produced as the company is extremely small.  The wait time is usually 6 months or more.  I believe Art Ferris is either retired or semi retired.
