You don't say what the brand or model integrated and preamps you have had problems with. I am curious. I have noticed that some people do seem to have endless problems with tubes while others seem to have very few. I am not sure why that is.
I have had tube equipment for decades without much trouble. Ever since I heard my first tube amp. I have no hum or tube noise even with my phono preamp. I do use balanced cables which great cuts down on any possible hum. And I buy high quality tubes from a very reputable tube seller. He screens tubes for noise and microphonics. This is very important especially with phono preamps. I also stay away from inexpensive tube gear that uses cheap transformers.
