Thinking of modding my 834p, or should I move on?

I have an 834p deluxe and it needs a small repair. The cost of the repair isn't that much off of having some additional modifications performed, and once the board is desoldered, I was thinking...I may as well go whole hog! However, I am wondering if investing nearly 1k in modifications is really cost effective. I use a Koetsu Black and am thinking of moving up the Koetsu line and/or buying a Grado Statement Statement. I've read quite a few times that the 834p transformers are not that great. The Deluxe sells for around 900-1000 used, so for 2k I could perhaps buy the EAR 324 used or look at something else, unless at even 2k, the moddified 834p would be a solid investment. I like the sound, but I admit I don't have much experience with phono stages at all, and this is the only tubed one I have experience with.

Any input would be welcomed.
