I just finished breaking in my LS15 after the infinicap upgrade and new tubes and dampers. I'm extremely pleased in every way, ARC was a pleasure to deal with, and it was only gone 10 days.
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.
