I have been using Audio Circle for well over 10 years. Based on the software I have never introduced myself. Well, here goes.
I have been active in aduio for over 50 years. I have built countless sets of speakers over the years. I built a Hagler power amp some years ago. I really had the time and resources to delve into DIY audio the last 20 years. I have built tube amps and have experimented with various class D circuits.
I am considering building a tonearm and possibly a turntable. I attempted a search here, and I found I had to introduce myself.
I am a retired IT professional, and I currently do some limited co sulting. I coached high school lacrosse and I officiate high school basketball. I live in Northern Virginia outside of Washington. D.C.
