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.
