I currently have an all in one Aiwa Dolby Surround setup with triple CD, twin cassette, etc (emabarrassing but probably about 5-6 years old) which I am about to ditch. I am about to purchase a DVD/HD recorder, probably the Panasonic DMR-EH60D, along with an AV Receiver, probably the Yamaha RX757. My speakers are Acoustic Energy Evo 1 fronts and centre plus a Mordaunt Short MS 307W. My rears are currently a couple of small computer Boston Acoustics on lightweight stands - very good for a computer and adequate for my current set up. My question is, will my rear speakers be completely inadequate for my proposed setup or, put another way, is the quality of the rears that important? Also, the Yamaha has a 7.1 capabilty. If I were to make full use of this by adding 1 pair of new speakers would the Bostons be better as the sides or the rears bearing in mind the sides would have to be located temporarily for listening and stored when not? One further point, any more, or other larger, speakers in the lounge is not going to be met with "enthusiasm"!!!
