Well, Eldragon, I guess it is how you read a review, when you say ACI Sapphire "blew them away". True, Mr. Potis preferred his reference Sapphire speaker to norwex B-2 Nisse in some areas, but he also said:"Treble performance from the B-2 was very good and a touch sweeter and smoother than ...Sapphire." And later he again comments about the treble performance compared to the Sapphire this way:"With the Sapphire III...the vocal sibilants were harder and more irritating." Personally I get very quickly tired when I hear too much treble energy. But, it is probably just a matter of personal taste. Also keep in mind that the B-2 Nisse was specifically designed to be placed close to a wall (bookshelf, wall unit, wall brackets, floor stands placed close to the front wall). Try that with Sapphire for comparison. Harald Aasland
