I am only about a year in as a true Audiophile hobbyist. I have always been big into music and sound systems but had never dabbled in the High End Hi-Fi world before. I built this system over the past year and almost everything is second hand through e-bay, craigslist, and amazon marketplace. I think I am done messing with the system for now and will be spending my team really enjoying this setup and running it through its paces.
Keep on the lookout for the Gallo sub amp for the 3.1s. I have this setup, and the bass is wonderful. You can then sell the REL to recoup some of the cost. You could also consider the Dayton Audio sub amp.
