Sure, they care about the look of it so it matches the window treatments.
But I don't think this should be confused as a "turn-on".
Now since you bought the NAD for her that is great - I gave my wife some Epos speakers....which is about to go on Audiogon becuase she is really not interested anymore in the idea of that 2nd system.
I can say that during my time being single - not a one thought my system was a turnon, let alone the speakers
BTW - my interpretation is you are not living together. If you ever do, or exchange the I do's -
Try this exercise :o) - come home one day and say, "honey I would like to max out my (no our) credit card and purchase some 20K Wilson speakers (you know the cheaper speakers that Absolute sound reviews), with the pretty paino gloss finish.
Also that money we were saving for our vacation and kitchen renovation will have to go on hold for 5 years or so as we pay off the speakers and the 10% interest". It may be longer as I may need to purchase another AMp to monoblock it to drive those babies better...can you please move your grandmother's antique table to the other room or put it in storage so I have more floorspace"?
I am saying most of this very light hearted by the way, please take this as conversation...but i don't think I am that far off base.
