Lyra Atlas SL Cartridge Magnet type??

Pretty sure it is a neodymium magnet...like the rest of the line. Far superior to Samarium Cobalt or Alnico IMO...
BTW, anyone know what a 'Platinum magnet' is??? Certainly not Neodymium....LOL.

@geoffkait  The reason that I asked about Platinum magnets is that is what is utilized by Koetsu on their upper end models...and yet the question is..what exactly is a Platinum magnet? IMO, it is a marketing name given to a somarium cobalt magnet...which as we know is inferior in its gauss to a neodymium. @bukanona.  The answer to your question is widely available on the web.

@bukanona  LOL, in my books if a magnet is stronger...by definition it is superior. YMMV.

@intactaudio Ok, is it as powerful as neodymium? I doubt it.

I think the factor of magnet strength has more to do with the design aspect of the cartridge motor...and possibly how quickly the coils will react to the signal. Personally, I think the trend to ever lower output cartridges is a negative aspect when it comes to cartridge ability. While the lower output is connected to fewer turns of the coil, thereby theoretically reducing losses at this point, I believe that this is more than off-set with the issue of increased noise at the phono stage...due to the phono stage now having to work harder ( and sometimes a LOT harder) to amplify the smaller signal. While some ss phono stages are still relatively low noise as they increase their amplification, almost no ( maybe 100%) tube based phono stages can say the same thing. Even with the ss phono stage ( or the transformer stage) the increase in noise is most likely a factor as amplification increases.

@zipost   The reply you received is exactly why I opted for one of Jonathan's designs. IMHO, his designs are far more advanced than just about anyone out there. For example, the old motor design of Koetsu's, VDH's and Kiseki's etc is really no longer competitive, IMO.

@zipost   Unfortunately, I think choosing a cartridge is the most difficult thing in this hobby, I started a thread somewhere on the web about exactly this....due to the inability of one to actually hear the design before purchase. Some folks really dislike Lyra’s...because they claim them to be lean...others really dislike Koetsu’s, too warm. I think if..a big if, you can hear the cartridge in your own system before committing, that will be a significant plus. Good luck with your acquisition.

@zipost keeping in mind that what I look for in a cartridge and what my preference is in music are probably totally different to what you prefer...I would say that all of those cartridges are good. The order is going to depend on what is your preference.
Personally, I like a cartridge that is not veiled and therefore is highly resolving...which would lead me to place the Atlas SL at the top, followed by the Airtight ( which does everything well...and nothing exceptionally), then the Zyx (not xyz)Universal...with the new CF cantilever and lastly a draw...between the Koetsu and the Allaerts. If more warmth is desired, I would tip that towards the Koetsu in favor of the JA. While you say phono stage is no issue, that surprises me, as the Atlas SL is very low output and the Opus is not....leading to a different presentation based on your phono stage capabilities.

@zipost   Diamond coated boron is not a solid diamond cantilever. A diamond cantilever is exactly that..a solid diamond one piece cantilever..made from an industrial diamond. 
Solid boron rod is what is usually used when the manufacturer states boron cantilever.

Good questions.

Anyone buy a new Benz in the last year? Not an old stock that was new...but actually one produced in that time period.
