Hope someone can help out here - I have Ruark Prologue 1 fronts, Ruark Epilogue 1 rears, and a Ruark Dialogue1 centre - sub bass is the Ruark Logrythm. Yup, I know, a bit Ruark heavy but it was a very good deal at the time. I have posted about this in the past - but couldn't come to a decision; it would be nice to have my setup back in action again before Xmas!!! These were powered by a Yamaha DSPA2, now disposed of. Any thoughts, particularly as this new Sony STR- 555 receiver has had such good reviews, on a decent amp/receiver which would be a good match? Budget is up to £800 max, excluding the extra speaker for 6.1. Thanks in advance.
