Obbligato's were so nice in my 45 amp I had to put them in my ARC LS-1:
Replaced the .47uF couplers with the copper case and 5uF outputs (removing DOUBLE by-passes) with the big oilers. All that real estate ARC provides; had to be done.
Just a few hours on now but there is a noticeable improvement in soudstage depth which was fairly 2 dimensional with the old caps. Also a slightly "sweeter" tone than with the old Rel and Wonder caps.
If you have the room I can't recommend these oil caps highly enough. I cut off the leads leaving just enough to make a loop and then run 24ga. silver wire to the board. It makes a difference.
