You could have asked the same questions minus your attitude.
OP, no matter what medium is hooked up, you're still not going to get an accurate representation of the sound as it pertains to your home listening environment.
The room, amp, pre, power cables, interconnects, etc. would have to be identical to yours.
The best you can do is listen, and if you like that particular speaker's sound, arrange an audition in your home to see how they sound there.
