Happy to be able to join. I'm a retired engineer with a lifelong passion for hifi and too much time on his hands. I have posted at other sites (mostly minidsp) but find that certain areas of expertise reside here, and I am always in need of expertise it seems.
If you use Facebook or Twitter, click on the supplied links and follow us! It's a great way to find out about new equipment reviews, news, and HTS forum announcements. We also feature lots of other content.
Also, if you have a completed Home Theater or Two-Channel system, get your first five posts out of the way and create a thread about your room! You can create Theater threads (here) and Two-Channel channel threads (here)! If you're designing and building, we have threads (Theater and Two-Channel) where you can feature your builds, too! It's a great way to share photos, ideas, and get feedback!
