I was at the Circuit City yesterday looking for some sale items. They have the HK525s on their floor and 7200 on their website. I was talking with their sales rep. and he said 7200 may get withdrawn and newer model may come in soon. Basically suggested their price could drop. He also said that HKs 630 is a digital reciever and they are good and similarly priced as 7200. Now I am Confused What is a digital reciever? Should I go for a digital reciever now? I tried looking at the forum's HT Beginners primer. But could not get much understanding about the digital receivers. Can some one enlighten me. If I stick with 7200 and go with it, will I be missing something down the lane for not buying a digital receiver? I am atleast not planning to change the receiver for several years. Thanks Kumar.
