Pedja buffer question... again and again

[Dxvideo]

Hi all,

As somebodies will remember, I have finished my last ultimate gainclone based on Pedja Rogics JFET buffered LM3875 design.. It sounds really good, the listening tests are still in progress.
But I think there will be no need to change something as my poor ear experiences.
Anyway,
Last night while I was in toilet I thought that its a good idea to put that Pedja's buffer before a PGA2310 (or 11) preamp!
Why?
- If PGA needs a buffer before himself
- and if we need an expensive opamp like OPA627 (20$ each and at least two needed = 40$) for best sonic result
- and Pedja buffer is the most optimum buffer because it costs nearly nothing, has no feedback, works in class A and I really like it..
So, do you think its a good idea? Will I face any problem like impedance unsuitability or something else?

PS: in Turkish we have a word that; "Shiny ideas come when only youre escaping or shi tting" (for Turks only)
