Uber quiet tubes for C2300 pre

Actually, I found that putting Walker SST or SST Extreme carefully on tube pins (for me it is a C2200 pre), whether the stock tubes or replacement totally eliminates any tube noise. The Walker SST is pricey, and even though the little jar doesn't contain much it is more than enough to treat 10-15 complete audio systems.
Try this first before replacing your tubes, although I highly recommend replacing the stock tubes; doing so will transform to an entirely new, and higher, level of performance.

Try some NOS Telefunken ECC83(smooth plates), 50's or 60's Siemens or Telefunken ECC803S(expensive) in the phono section,for the ultimate in accuracy and low noise. The ECC803S was manufactured specifically with those attributes in mind. Amperex and Mullard ECC83's, of course, will add warmth, if you are looking for that. Be certain they are tested and guaranteed, Low Noise. I do endorse SST or Xtream AV Quicksilver(applied VERY carefully), but neither will help quiet a noisy/microphonic tube.

Jgiacalo...I will look in to the Walker SST as I am really trying to lower the noise floor on the MC phono section.

Rodman...where are you getting the tested and guaranteed Telefunkens from? I don't necessarily need added warmth--a more detailed/precise tube is preferred. I mostly want dead quiet! What benefits do you hear from using the SST or Xtream?

BTW--I am using VPI Aries 3 with Lyra Argo i cartridge and XLO Reference3 phono cable--if that helps any.
