Wow this thread took an odd direction.
Too the OP If you can afford the GR by all means do it. I love thier ICs and have a lot of respect for the company.
The idea of changing speakers is a fairly radical thing to do if you really like what you get from the speakers you have now. I don't know them and can't say if they are essentially poor and other speakers are much better. You might investigate that through audition.
To repeat the straight answer is yes get the Cardas speaker cable.
