Hello All, Sorry about this one if a) it's a stupid question and I'm missing the obvious, and/or b) it's been covered in one way or other before. For one or both of the above I apologise. I have a Denon X4200 paired with Focal Domes sub/sat in a 7.1 configuration. The Denon is rated at 120 watts (125 watts depending on which specs you read) per channel. The Focals, though I can't find a maximum WPC rating, recommend a 25 - 100 watt amp/receiver. Taking into account the fact that the receiver rating is based on 2 channels being driven (I'm running all 7 remember) and therefore would be outputting rather less, would the diminutive sats that make up my front/centre/back/sides be up to running anywhere near "reference" levels (eg 0db)? The reason I ask is that having only gotten my system up and running after several weeks without a sub and just bought the Denon, I played a few films at around -3db to -4db without issue (SW Force Awakens and MM Fury Road - absolutely amazing sound) but when I tried the opening, apocalyptic, explosive, dino killing event in Transformers AOE I got a pronounced crackling at times through my speakers at anything above -7db. Any ideas? - and please don't tell me the solution is "don't watch Transformers...". That's just too obvious Thanks for any help you can give, Cheers everyone.
