Hey Guys! Been lurking around on this forum for a few weeks and decided to make a profile finally since I am looking to dive into the world of reps. Looking to buy my first sub rep in the upcoming weeks so any advice would be helpful. Seems that the ARF one is the best to go for straight out of the box. Any advice on swapping crystals or who to go to? Since it seems that is the major issue with the ARF Subs.
