Thiel improved with time with the last series being
CS1.7 , CS2.7 and the CS3.7.
I have the CS2.7s and love them ,
The CS2.4 and the CS2.4SE are also highly rated
models by owners to consider.
Size of your room and wallet should determine your choice,
the CS3.7 is not that much larger then the CS2.7,
but it is about 50 lbs heavier.
