Nice to hear that!! But what about ticks&pops? I would expect them to be more "intense" with the Replicant shape (than with a conical 103R).
Not at all.
In all respects relating to noise and vinyl artefacts, the A90 is uncannily quiet - ticks and pops are much less noticeable than with the 103R.
Of course it can't eradicate noise completely but, as I said above, it easily has the most silent background of any cartridge I've owned.
The quality of the stylus and how it sits in the groove no doubt has something to do with this. However ticks and pops seem to be more obtrusive as the quality of the cartridge carrier (turntable/arm) is reduced.
What I suspect is happening is that the 'ticks' excite micro-phonics in cartridge/arm/table. The better the cartridge body/tonearm/turntable are able to control/suppress this excitation, the less noticeable they'll be.
My TNT/Phantom is a pretty quiet platform, it probably also helps that the A90's body is designed from the outset to be highly damped and suppress resonance. The A90 was also designed with a flat response - a rising frequency response is not going to assist the noise equation.
The subject of vinyl noise artefacts is much more complex than merely looking at stylus shapes. To some extent the preference of stylus shape may
be dependent on the quality of the turntable/arm. Ultimately though, IME, line contact type styli will offer the lowest noise (when setup properly in a quality table/arm).
