It seems to me you have enough tubes in your system to experiment with some solid state options within your price range and quite possibly find a great all around over balance along the quiet attribute your looking for. I have tried Peter's Liberty b2b-1 phono stage and loved it especially the stereo separation it provided. And it was very quiet. At the time I had a solid state amp so it was a presentation that for me was needing some tubes at the time.
I was looking at your system, and it's very nice, I was looking to see what you had a couple things plugged into and I could not quite make it out but It looks like just a basic sorta small multi outlet deal. If so that might be a weak spot source for some noise issues in a system.
