Hi all existing / ex KEF Q50 owners !

I owed the KEF Q50 Floor Standing Speaker, and is still happy with its performance.

However, the Q50 has been used for 10 years, and I am considering of whether any possible upgrade is "worth" the money ?

My current setup :-
Surround Receiver : Marantz SR7000
Front-Speaker : KEF Q50
Center-Speaker : KEF Reference Model 90
Rear-Speaker : Goodman Arena
Sub-woofer : KEF Model 20B
DVD/SACD Player : Philips 963SA
CD Player : Arcam Alpha One
Power filter/surge protector : Furutech 168

Any suggestion / recommendation ? or in fact I can still kept my Q50 and enjoy it for some more times ?

My prime requirement is "Sound quality" in both Movie & Music.

If I were you I would think about upgrading the Goodmans rear speakers before anything less, especially if you play much SACD multichannel music
