I think the rack can make a difference depending on your needs. Any rack with a good damping factor and ability to "drain" the energy may be of benefit to you. At one time I wanted a rixrax or symposium rack (5k), It would still be nice It's like buying jewelery both are stunningly beautiful. Do I need to spend that much, No of course not. Do others need to spend that much? well maybe. Remember synergy and balance is what makes a system really great. It's not how much money you can throw at it. I figured that out when I hit the 50k mark. Now I have my system on a great rack (don't laugh) from Staples I got on clearance for 49.00, (you can't get them there anymore) It has the best damping factor of any inexpensive rack I could find. The shelfs are thick but not solid, If you tap on a shelf It has a nice quick ring and then does dead. They are some kind of practical board covered with real wood, they are also reversible if I decide to change to a dark cherry. But sense I seem to like change I have plans of replacing it what a nice vintage danish piece. (At least I won't be out much money)
All that said, you have a wonderful system, it looks great on the rack you have. You could play around with different racks but keep what you have in case you want to go back.
