I am a Ortofon Advocate, I know the house sound well and have a familiarity with the Tonal differences that can be detected across a range of few different Models released at different era's, as well as Hybrid Models that are not entirely Ortofon.
I do have my favourites, but less favourite models when given extended playtime and not just the time given for comparisons have the ability to make a good impression.
I lean more to the range of models using Silver Wire for the Coils, as the Aucurum Gold Plated Copper Wire used on models has a Richness of Tone, easily detectable to myself, which moves away from the Transparency I really like.
If Aucurum Wire was my only Option as a Coil Wire, I could easily overlook the Richness of Tone, it isn't the same Weighty Tonal Influence that is easily detectable from Cart's using certain types of Wood as the Body and thick Coil Wire at around 0.05mm - 0.07mm.
What is not discussed openly is the Ortofon Research into Rubber Compounds to support the Medical Industry and how that research lends itself perfectly for the Damper selection on Ortofon Cartridges.
I know an individual who has investigated Ortofon Cartridges Dampers from Cart's that are between 20 - 30 Years Old with a exposed to a typical environment for this period of time. Their Assessment being the Dampers show no signs of being effected by the ambient environment and longevity of being used as a Damper.
There are Brands of Cart's that come with a cost that is substantially more than a certain range of Ortofon Models, and it is known that there are Brands Dampers that are shot prior to the Cart's initial 1000 Hours of usage, or Dampers shot before 2-3 years of ownership has occurred. Probably Shot whilst the Cart' has a warranty but the fault present is not known to the Cart' user.
Looking at Ortofon will show stories where there are historical accounts of quality concerns for a Stylus Bond to a Cantilever, but interestingly numerous Cart's have similar reports clise to them during a particular era.
Looking at Ortofon is certainly not to waste ones hard earned money. The longevity on offer of critical parts is just one reason to feel one is releasing their monies towards a sound place and the purchase is based on being sure footed.
