Dear all AV Forums Friends ! I am currently using Marantz SR7000 Surround Receiver (for several years); while I recently saw the great review on the new Cambridge Audio Azur 540R (from here :- http://www.homecinemachoice.com/cgi...p?reviewid=4344) Don't know whether it is worth to upgrade from the SR7000 to 540R ? My main requirement is to improve both Movie surround sound and Concert music sound. Here is my existing equipments :- Surround Receiver : Marantz SR7000 DVD/SACD Player : Philips 963SA Front-speaker : KEF Q50 Center-speaker : KEF Reference Model 90 Rear-speaker : Goodman Arena Tube Amp : Houston Mini-2 CD Player : Arcam Alpha One Power filter/surge protector : Furutech 168 Sub-woofer : KEF Model 20B LCD Projector : Sanyo Z1 I am looking for any advice & opinion, many thanks !!!
