Wow your system must sound rough to warrant a �7K upgrade. (Joke)
I spent less than that on my whole system and it sounds staggering. (IMHO). 506CD 518 565 A500 M33c M1500 sub etc.(True)
My advice, and I understand if you dont want it, is dont do it with out a audition because if your wrong, and that is a 50/50 chance you will struggle to find anyone who wants to pay that much for a CD player.
The Law of diminishing returns is a play here, big time.
Go out and see a few concerts, you will be surprised just how good your sound really is. Are you trying to get a sound that just doesnt exist?
What do I Know, you can buy alot of discs for �7K, see alot of shows as well. Pay a big chunk of the morgage. Get a nice car.Buy some investments and use returns to buy HI Fi.
The world is your Lobster, enjoy, Chris.
Wishing I had �7k to spend on my system.
