retubing and would like to hear input from others

Hi all,
I recently switched from ss to valve gear and am starting to retube, getting rid of some sovtek and cheap chinese tubes. I picked up a cherry counterpoint sa-500 and a set of coincident mp300b monos. My first quandry is with the rectification and power regulation sections of both the pre and power amps. When choosing tubes for rectification and regulation(5ar4 for rectification on mp300b, 6ca4 for sa-5000 rectification, 12ax7 and 6dj8 for regulation). With these tube sections, is a low noise tube required/beneficial? I would also greatly appreciate some input on other peoples impressions of different 6dj8/6922 used as phono and linestage drivers.

Thanks
maplin

Try a website called Joe's Tube Lore on Audio Asylum . He has done exactly what you are asking for with the different input tubes . Now he did not do the shootout using your equipment , he used a Thor preamp . So take that into consideration .
