Ssssh, is your tube preamp really that quiet?

I've owned many very quiet tube preamps. Are you hearing tube noise with the volume knob set at regular listening levels in between CDs/LPs? Or are you turning the volume all the way up with no music playing to see if you can hear any noise? I find that on a lot of tube preamps, if I turn the volume all the way up and do not play music I can hear some noise....but I really do not see the point in doing this. With the volume knob set at regular listening levels my tube preamps have been mostly quiet.

If you are having this problem at normal listening levels, have you tried changing out some of the tubes?

I'm actually talking about when the volume is turned up and no music is playing. IOW putting one's ear to the speakers without the CD or LP playing and at a typical volume level. The noise is then evident, which I would believe would lead to some impurity slipping into the playback once music is playing. Even though this would seem on the face of it to be inaudible with music, is it really?
Complete silence at all volume levels isn't something that I have heard any tube preamp accomplish, ss OTOH I have. Therefore, my question IF anyone has heard or knows of a tube preamp that can accomplish this.

With 106db single driver speakers and 10 watt set amps at normal listening levels with no music playing, I hear not the slightest peep with my ear one inch away.
Preamp is Doshi Alaap.
I imagine tube choice may be a slight factor.

Not the slightest sound with ear at the tweeters and rather loud volume setting with my DeHavilland Ultraverve & fairly efficient Tidal Piano Ceras.

101 db Zu Definition 4 with an Art Audio dm VPS tube pre amp and Art Audio Carissa 16 watt SET tube amp- not a hint of noise at full volume, ear at tweeter, with no music playing.
I suspect tubes? As mentioned above, try rolling your pre amps tubes. I have had noise in the past but corrected this by simply removing a noisy tube.
