Tube recommendations

Hi all
The phono stage within my pre currently uses these 3 stock tubes - Sovtek ECC83, Electro Harmonix ECC81 & ECC88 (I think it's Tung Sol).
As I'm new to tubes which tubes would you recommend to be a significant  upgrade?

Thanks 
Rich

InfectionThe ECC83 tube is the same as 12ax7 tube. I recommrnd telefunken 12ax7's if you can find them . Huge upgrade over sto ck sovi et ecc83's which came with my phono stage.Are you sure the third tube is Ecc88 or is it E88cc?the ECC88 is a 6922 tube type. Same here i recommend tekefunken or my favorite,  Siemens.

I believe shadorne may have the tube substitute number for the 6H23 incorrect. I believe the correct tube is 6922. Another good source is Upscale Audio.com. they also have good user reviews on tubes and good selection. 
I have never had problem with any tubes bought from them.With regards to Telefunken tubes vs Gold Lions. I have used both companies 12ax7 tubes in my phono stage. The Gold Li on tube is best value for money but they are not as good as the Telefunkens.
