SET vs Push-Pull (Line Magnetic vs Primaluna)

Thank you for all your responses!
The feedback from the community is quite helpful. 
I thought I would provide more detail about my listening environment.  The room measures 20x24x9.  The 24 dimension is because the room is open to a staircase and a hallway.  The listening area is more like 20x16.  The speakers are about 9’ apart, and my listening position is about 9-10 feet from each speaker.
My average listening level, measured  at the listening position with a decibel app on the iPhone, measures 70-75 dB, with peaks rarely above low 90s.
I agree that the best way to make the decision would be to arrange an in-home demo.  This may not be possible, so I might have to take a trip to the nearest dealer (2hrs away) and make a leap of faith.
In the mean time I’ll probably change the output tubes in my PL from EL34 to KT150, just to see how that sounds.
Thanks again!!

I did some more listening this afternoon with the decibel app on my iPhone.
I find that when I am listening at what I would consider a fairly loud listening level, it’s reading average levels around 80-85 dB, with peaks around 90.
this is measured at around 3 meters from the speakers.
Newport Beach is closer (and cooler) than Palm Desert, so I might make a run up there (Excel Audio).
thanks….
