Budt. There was nothing wrong with the setup or the speakers in question. Sometimes one persons slight improvement is another ones vast improvement, but hey, you heard what you heard. I respect that. If you look at what B&W did as far as the upgrades with the new Diamond series, it's not hard to believe the speakers would sound similar. First, it appears there has been nothing done to the cabinets and Marlan inclosures for the midranges and tweeters except for some trim cosmetics. Tweeter has some minor mods mostly with more magnets in the motor structure and a different surround material for the dome. This was mainly to maintain flat frequency response at very high power levels. The midranges appear to be basically untouched even in regards to crossover points. 80 percent of the music you hear in a loudspeaker comes from the midrange. Bass drivers have modest changes also still using Roacell cones. The bigest improvement to me seems to be the higher quality caps which are in the high frequency section of the crossover only. The caps in the older "D" series were also very good and made by the same company called Mondorf. I know I've mentioned what seems like alot of changes but these all seem pretty minor, at least to me anyway. I did note some minor improvements to the sound, but once again not world beating to me. Just my opinion.
