New to the audio game but i want and respect quality sound. I should be staying low budget but i want to make purchases that will allow me to upgrade to a mid end 7.2 home theatre system. I just purchased a Yamaha RX-V673 7.2 I was going to purchase one of the following: [*]JBL CS480B [*]GMartinLogan MLT-2 [*]Energy Take Classic 5.1 [/list] Then i got reading and was under the impression this wasnt the way to go having a decent reciever. Is it a good idea to get a 5.1 then match up two other speakers in the future? WHat subwoofer is reccomended in the $100 range. Should my two others be of higher and and be my fronts? Do I slowly buy higher end compnents to get the most out of my reciever? I wont have room for towers which eventually i would love to have. Im in the miltary so room size is a little unpredictable but average size is 8 to 12 ft viewing distance. 14ft by 17ft room being the biggest and will vary by about 4ft. Your advice would be greatly appreciated.
