Most of these posts are re-hashed. Do a search on Fi Primer or SRPP and you will see they have been well researched and thoroughly discussed. I have two SRPP SETs and my next one is not a SRPP set up. And as you mentioned, knowing what you like and isolating those variables is important. Also, I can't say without certainty that the tube choice of a 6SN7 for the SRPP may not be ideal. There are lots and lots of other tubes besides a 6SN7 that may sound better under that circuit. Same could be true of the other circuit. Your reasoning may make some sense if you can isolate all sets of variables and then conclude that using a 6sn7 under the "fi" versus the "srpp", that the Fi is preferable. It would be hard to conclude that in all forms a SRPP circuit does not sound as good as your Primer circuit., given the lack of study of a wide variety of tubes along with a wide variety of choices and engineer makes while building each circuit.
