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,

I heard the ICs go out and are not replaceable then the preamp is done. I heard allot of those are now failing, as they are nearing the end of their usefull life. I have a SF preamp and it had a nasty habit of going to full volume in one channel- exciting, but not for me.
