Thanks for everyone's input. I am in a rental apartment in NYC for about a year before I buy a house in the burbs. Regarding my current cabling and interconnects, I am using Nordost Solar Wind interconnects (the dealer gave me two pairs when I bought my integrated). If you think any upgrades would help, please let me know. Sounds like speaker cables are the first step. I have not done anything with my power cords to date. My dealer in NYC is letting me borrow some Blue Heavens next week. If there are any others that you like in that price range, let me know.
Again, thanks for everyone's input.
John
