Hey Raul,I can't really answer for you,though I have some theories.Firstly I always use a Decca record brush just before taking the LP off the platter.I also use a soft brush(actually a facial make-up brush)to dust off any dust(which I seldom see),which may accumulate on the platter,during a listening session.Most importantly,I am lucky enough to have a dedicated listening room.All this probably helps.
BTW-Just as a fun point of interest,I went to the VTV show today,and heard my first Allaerts.Not the top model,and not a system I am familiar with,yet,and yet it was clearly a very special "musical" experience.You are correct(based on my limited experience)in calling these really fine transducers.
Also,and this was interesting,and fun,I heard a system(one I'm fairly familiar with)that consisted of Horning hybrid speakers,Tron amps,the WORLD CLASS Japanese Audio Note preamp(more expensive than any car in the parking lot),and TWO Davinci tonearms.One arm having the Myabi Ivory cartridge,and the other Davinci carrying the XV-1s.These were on a very fine table(quite massive).We compared both cartridges using the same LP tracks.Miles Davis' Kind of Blue( I own the "six Eye original").Well I was surprised as to how distinctively different both these cartridges sounded.I knew they should,but they were really different.BOTH were quite superb.The Myabi was the more romantic and warm sounding(in a good way),with fine detail and timbrel character.The Dynavector was EVERYTHING I had come to hear about it.It was the more neutral,but was "KILLER" good at digging into the recordings we played.More dynamic, but I could easily live with either.Yet to tell the truth,based on the "littlest" Allaerts,I'd have to say that my appetite is paused to hear the Allaerts "big boys"!I have a sneaky suspicion that they might be the "ones"to cherish,and pass down to the grand kids. -:)
Thought you'd like a "good read",so sorry for my length,here.
Best!
