@wheezer1 Fully agree. I've tried several others through the years which only lasted a short period. Only the Russian ones last a long time. Keep in mind that the originals, as matched pairs are becoming more difficult to get. There is a lot of fake offered.
Audible Illusions Modulus 3A noise
I purchased the AI M3A, love the sound, do not like the high noise floor - much more noise on one side now after only 10 hours or so of use. Reading through forums I suspect the electro-harmonics tube. Is a louder than normal static noise coming through speakers normally a tube issue?
Thanks for your help!
