Definition Mk IV's are in the house!! First listen (without a minute of burnin) showed great potential; however, they have a tightness that is not natural (burnin issue I assume?).
I had been doing a great deal of listening to my previous Mk1.9's lately as I tried several different amps (more on that later) so the differences between the speakers are REALLY obvious to me. Inner detail, microdynamics, macrodynamics, and top-to-bottom coherency are all improved upon in dramatic fashion compared to the 1.9's. The top treble, even in this unplayed state is more open and expansive.
I will say the sound quality is changing rapidly in the first few hours of play...not really better, however. Seems bass has gone AWOL (receded in level relative to rest of frequencies), the sound is punchier (they were punchy from the beginning so this is not necessarily "better"). All told, my impression is that these speakers need hours of play before they start revealing all that great inner detail and micro/macro dynamics in a natural way, rather than a punchy way. Anybody else notice this during the early hours of play? How long before they "relax" a bit?
I have them playing music at a moderate volume level and will continue to play them throughout the day and weekend straight. Does anyone have an informed opinion on whether playing the Purist Audio Burnin CD for extended periods will help hasten the burnin?
