Tube Question - Significance of Tube Noise at Listening Position

Hello all.  I need some advice on tubes.  I use a BHK preamp that has a tube input stage (12AU7).  I recently replaced the PSvane tubes that came with it with some GoldLion gold pins.  The sound is much better, more holographic, warmer.  However, after 6 months, I started to get tube noise with my ear near the speaker.  I put back in the PSvane tubes and the noise was reduced in half so it is the tubes, but with the old tubes, the sound quality of course dropped. 

I am thinking about buying some new tubes, either Ray Select tubes, which are considered to be very low noise, or NOS Brimars. 

My question is: does the tube noise matter at the listening position if it can't be heard where I sit?  Although I don't think I can hear the noise at my listening position, I am still bothered by it because, well, its there.  We work so hard to get black backgrounds and I would never use a cable, power cord, streamer or conditioner, that adds hiss.  We would never accept that, so even if I don't hear it at the listening position, I just feel like it must have some detrimental effect and why should we accept that from a tube if I won't accept it from any other component?  

I am looking for advice on this topic and if I should get the Ray Select tubes to hopefully remove the noise, or go with the good sounding GoldLions even though I know they are adding noise/hiss/garbage to the sound near the speaker. 

Finally, anyone have any comments on the Ray Select 12AU7.  I don't want bright or hard, and the competition is the GoldLion gold pins. 

Thanks everyone.
