Am thinking along the lines of AVR 300 and DV79 with MA Radius, hopefully 4x R270, R225 and R360 although may have to settle on the R90 as rears if spending more on the electronics. Are Arcam and MA a good match? Music is at least as important as movies if not more so. I will be doing some listening test but would appreciate some advice in advance. How much improvement would I get using four 270s rather than R90s as rears? I have read many times that the AVR300 works best using the rear channels to biamp the front speakers, is this really necessary to extract the best sound quality? The Radius 270 only has one set of speaker terminals, so is there an alternative I should look at? Am keen on MA as used to own some of their hifi speakers, which I was very happy with. Also, have many good reviews of the Radius system, naturally it looks good too, which is also a consideration. One thing slightly putting me off the Arcam gear is that they appear to have a long shelf life. The DV79 has been around quite a while now, while many manufacturers seem to replace their range every 6 months or so. Would I be better off waiting for the new Pioneer combo of VSXAX4 and DV 989, or even their Denon market equivalents from both sound quality and technology perspectives? Is there a new Arcam dvd player on the horizon? Ease of use is also an important consideration, not only every day operation but also minimising number of connections, set-up etc. Any advice greatly appreciated!
