Ortofon MC X30 broken cantilever - what are my options
@maam522a I suggest that you also ask Ortofon to tell you the reason for the cantilever failure. If it was caused by a manufacturing issue, they should take particular note of the problem so that the appropriate countermeasures can be put into pl... 
Recommended a highly resolving cartridge
The Decca London absolutely does have a cantilever, as can be seen in the following diagram from Stereophile. The article that it came from can be found by performing a web search for  "Stereophile review of the Decca London Jubilee / Reference... 
New cartridge vs. Re-tipped
Hi @neonknight: Before answering your question, many of the cartridges that are returned to us for service are ailing due to factors that are within the customer's power to control. For example, inadequate cleanliness in the cartridge operating ... 
New cartridge vs. Re-tipped
On a few occasions we have been contacted by Wally Tools and other cartridge inspection services regarding excessively lax stylus alignment tolerances of Lyra cartridges. The customer had bought a new cartridge, and was displeased with the results... 
Matching the cartridge to the phono stage
Hi @lewm  "That’s often tolerable but also there is a gradual high frequency roll off." The statement quoted above will be true if the cartridge is an MM or MI with hundreds of mH inductance. In contrast, MC cartridges generally have far less i... 
A Story about a Defective Signature Platinum
Hi Mijo: Rather than problematic solder joints, it is more likely that the issue that you are experiencing is caused by (very small) pinholes in the insulation of the coil wire. The armature onto which the coils are wound, moves together with th... 
Ortofon Kontrapunkt C vs. Cadenza Bronze
Thank you, Raul. Audiogon staff were able to sort out the technical issue, and I am able to post again.  
Lyra and OMA
A key role of a tonearm is to function as a mechanical high-pass filter for the cartridge. Roughly speaking, above the resonance frequency the tonearm stays still and allows the cartridge to follow the LP groove, below the resonance frequency the... 
Lyra and OMA
@o_holter  Experimenting with adding mass to a tonearm (presumably to the headshell) may help dynamics and low-frequency weight and extension, but doing so will also push the counterweight farther away from the tonearm pivot, which may trigger ad... 
Lyra and OMA
Hi ​​​@michaellent: I agree with @tomic601 and @solypsa that a tonearm with only 8.5g effective mass may not bring out the best sound that a Kleos is capable of. No doubt that the combination will track well, but possibly with reduced energy in t... 
Mono Cartridge Question
FWIW, for the past 20 years Lyra has been making mono cartridges with vertical compliance (but no ability to convert vertical motions into electrical signals) and line contact styli of similar dimensions as a microridge (the contact radii of our s... 
Lyra Etna Lambda SL tracking force
FWIW, Peter sent me an inquiry through Audiogon's private messaging system, to which I sent a reply on Dec.11. Although Peter has therefore had the information that he was looking for, let me quote the relevant text from my reply, for the benefit... 
Brand new Lyra Delos - skewed cantilever
Hi @anthos314 : Thank you for your photos dated 06-21. In my opinion they show a worrisome level of dust; the heightened distribution of dust closer to the LP surface indicates that this dust comes from the LPs being played rather than a generally... 
Brand new Lyra Delos - skewed cantilever
@mijostyn , Lyra cartridges are hand-made, and as humans we can't claim to be infallible - but when there is an issue that could have been caused by our manufacturing, we try to work together with the customer, our dealers and distributors so that...
