Looking forward to hearing the new Alta Audio Adam speakers, but need a Reference Speaker for my maim system.

2: One in the living room, and one in the car.

I've got two besides the main system..A guest bedroom system with a vintage Pioneer receiver and Celestion Ditton speakers and a very modest HT setup in the family room - Old Audiolab integrated, Polks, Sony Blue ray. 

My second system is in our finished basement,aka The Pit. Currently running a First Watt F5, Promitheus TVC, Hornshoppe Great Horned Heils, April Music DAC, Bluesound Node 2, and an Onkyo C-7030 (running thru the DAC) 

2 systems here. 3.0 HT for TV in living room. Tube amplified vinyl/cd/tuner system for music in spare room. Don't know which is second system, one used more, one better sound...go figure.
