Thanks Kittu & other fellow members for your suggestions.
currently my setup is already 7.2, i am living in a flat, my listening room/ Hall
is not that much big. see the photo.
I just want to change my Front floor stander only.
as Kittu advised then i have to wait for some more time & then buy some good Amp & speakers.
I want to keep my Rx-V667 for long term.
Regards,
