Dear Dkarmely: There is no doubt that you are a passionate music lover an audiophile and a in deep admirer of the 927 and so deep that maybe you a are leaving some importants facts or at least not mentioned yet on the 927 quality performance.
I have no doubt either that at engeneering level the 927 is a " tour de force " and I would like to know how that so high level of engeneering is reflected against some facts/specs/measures that speaks about one of the main design TT targets named accuracy. I think that first than all when we are talking at this so high level of designs we have the right to know how accurate is the item.
So, how it compares on signal to noise ratio for example against the Exclusive 3a that measures 95db? or against the Yamaha GT 2000 with a wow and flutter of 0.0025%? or the Technics SP10MK3 speed stability of 0.0001%?
Engeneering must be reflected on accuracy characteristics against what is in the market, especially when we are saying that the 927 is the " holly grail ". Maybe you can put some " light " about.
Now, I agree with Tonywynsc that neutrality could be the " perfection " that can't be achieved but ( again ) when we are touting so high the 927 is reasonable to ask for that characteristic that as Peterayer said is plain and simple: " don't add or lost nothing to the recorded signal ".
Natural from your point of view and your examples posted is more a subjective parameter that means it's not neutral but only diferent with different colorations/distortions.
I never had the opportunity to heard the 170 kg. American Sound TT that's a different kind of design including its drive mechanism but I heard the Final Paruthenomn( 140 kg. ) that was an assualt to the state of the art on TT.
Btw, Mosin I think that is so elusive the neutrality target that you really can't find out that " boring " you said. But that's not the point, what you said seems to me only : how to find out a mistake on what I posted. I know that you know exactly what I'm refering when I speak of neutrality on TTs.
Regards and enjoy the music,
R.
