Hello from Florida

Thanks to you all that have posted questions/answered them as it has been a great learning tool.

I have a AS degree in electronics from the late 70's but have not worked very much on the PCB-component level.
Most of my work has been operating equipment to simulate environments and running automated test equipment with some manual measurements.
Currently I am installing and programing avionics equipment in aircraft.
I found this forum after connecting my computer to my audio received and wanting to get rid of the hum. I ended up buying a Schitt Modius DAC that got rid of the hum and gave better audio quality.
I have always wanted a mid to upper end audio system but could not justify the cost but at DIY cost I can. So I have decided to build a a10 Preamp and Wolverine Amp with your all's help.
