Constant noisy tubes maybe go solid state?

I have had tube phono preamps, main preamps and main amps for about 3 years totaling 9 models.  I progressively have had a quieter system with simply faint white noise audible from the speakers in the earlier models.  As I have reached my current higher end models, the noise is gone.  This was one of the benefits mentioned for my ARC gear both from individuals and official reviews.  

When I had some output tubes going out I also had a little of this similar noise increasing.  It was a bit inconsistent during this event where I would hear a faint whoosh sound.

It sounds like an odd run of bad luck you have had and makes me wonder if there is an issue with your gear.  Have you ever considered having the tubes tested?  I live in Memphis and The Tube Depot normally tests preamp tubes for $2 each.  I actually talked to them yesterday and their tester can even estimate remaining life.  They have stopped receiving tubes due to the damn virus, but hope to resume soon.  Whether them or any of the other companies out there...it would be good info to have.

Tube sound is glorious....don't give up!!

Does a faint white noise degrade the sound somehow particularly if its barely audible without putting your ear to the driver? 

+1 for Vintage Tube Services !!!

May not be just the tubes that are noisy.  I have had some noisy pre amps (Schiit, Decware) and changing tubes makes a difference but could never get a black background until I changed to Allnic.  Allnic doesn't have any sense of tube bloom, it is very detailed and quiet like solid state but has a sweet almost holographic presentation and a very strong accurate low end.  I can turn the volume almost all the way before I hear noise in my speakers.  I would never listen at that level.  I also found using single ended RCA IC's added to the noise.

Don't go solid state, the quicksilver preamps are great and amazing value. I have both versions (remote, non remote), super quiet with any tube (maybe I am lucky with the tubes). I now am using NOS RCA's. QS stock tubes are pretty decent. Mike is a great engineer, he knows what he does.
