Hi, everyone. I am a newbie to head FI, but experience with headphone and car audio systems for a few years. Also, the Sennheiser HD series (like HD650 700 660S) is my favorite. I usually used schiit BIFROST with LYR amp + ecc88 tube as my primary system to run them. And recently start to modify my corolla car audio system, which was so interesting while I can hear the different sounds from the new system. Hope everybody can enjoy my post and share your first system here.
