upgrade from Sonic Frontiers Line 1 to 3 SE+ ?


I have a SF line 1 with all the Amperex PQ 7038 tubes and have been quite satisfied with it.
May I know if there's obvious improvement if I replace it with a line 3 SE+ ?

Thanks,

Thanks for everyone's helpful suggestion.
Can I say upgrading from line 3 to SE+ also
has obvious sonic improvement?
Thanks for everyone's sharing of experience and suggestions.
I think I will move to line 3 SE then.
