Audio Research LS-15 Infincaps

I own ARC LS-15 pre-amp. Mine has REL caps. Later in production they equipped their LS-15 pre-amps with infinicaps. Has anyone compare the LS-15 with REL caps to the one with Infinicaps? If so, what are the advantages in sound of this pre-amp with infincaps vs the REL caps. I am thinking of sending my pre-amp to ARC for upgrade to infincaps. The price ARC charges is not a killer, but it's still few hundred bucks. Is it really worth it? Thanks in advance.

I had the LS15 with Infinicaps for several years and loved it. But with the right tubes it really took the unit to a whole different level. If you havent rolled some tubes I would add that to your list. Some of my favorite tubes were the Amprex BB, Amprex A frame, and if I had it now I would try the Ei 6dj8.
