Opinions please and this will be taken seriously. I bought a new AV32 Dual processor from Sevenoaks on my last visit to U.K about three weeks ago. VERY HAPPY WITH IT!! I am back to U.K in July and can have the upgrade to 7.1 with action switches etc for 400 quid. Aside from the action switches which would be useful but not essential, the 7.1 would only be used when I add the rear surrounds. Here is the question: - Is the quality of staff doing the upgrades of a level that my unit won't come back "damaged by improvements?" Don't forget we are here at the other side of the world so a quick trip down to Huntingdoom is not an option.
