KD, Are you running the SLP98p into the CAD211fe?
Can't speak to those tubestore sets, but I went with Psvane Tii 845 to replace Shuguang 845. Huge upgrade, all around. Then went with Psvane Tii 6ca7 to replace EHX. Mild improvement. Then went with Shuguang Nature 6sl7-t. I think (hope) those are still burning in. Pretty sure I prefer RCA 5691. I haven't touched the GL 300b, but am interested in opinions.
In the slp98p, I haven't yet messed with the phono other than to drop in Psvane 12ax7-t in place of new production tung sol. Interested in opinions on 12au7.
Although I haven't tried every combination, here are my favorites in the slp98:
Sylvania Jan chs 6sn7w black base into RCA greyglass vt-231 or into Ken-rad black glass vt-231. This is as close to magic as I've heard.
Budget combo--GE 6sn7gtb grey plate side getter silver label into Sylvania 6sn7gta chrome tops.
For new production 6sn7, only tried EHX and Tung Sol, and, well, working on acquiring a lifetime supply of NOS/vintage.
