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... 
Brand new Lyra Delos - skewed cantilever
@mijostyn : please be aware that the issue has already been taken care of, that Lyra has finished servicing @anthos314 Delos and he has received his cartridge back. Incidentally, the reason why this Delos had a skewed cantilever was not due to a ... 
Brand new Lyra Delos - skewed cantilever
Hi again @anthos314: Prior to sending the cartridge, please include a short note in the box with both the serial number and the nature of the problem that you are experiencing. Knowing this will help us focus quickly on the potential problem areas... 
Brand new Lyra Delos - skewed cantilever
HI @anthos314 : Improper anti-skating is a very common cause of cantilever skewing, but your photos seem to show some skew without the cartridge being on an LP, also I wouldn't expect improper anti-skating to cause the suspension to develop an off... 
''Óriginal parts'', ''identity '' and ''retip'' conundrum
@nandric >The reality is that all styli and cantilevers are not produced by manufacturer but by, say, two Japanese Jewel companies. This is more likely to be true for styli, less so for cantilevers and the other components that comprise the ca... 
Why do these Zyx Fuji and Airy 3 have such a dark sound?
Hi @rorosone 66º Farenheit / 18.9º Celsius is too cold. Under such conditions your ZYX Ultimate is likely to produce less high frequency output but higher distortion than what the manufacturer intended. AFAIK, most Japanese manufacturers adjust t...
