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... 
''Óriginal parts'', ''identity '' and ''retip'' conundrum
@nandric , having cantilevers made covers a fairly wide range of possible options. At the simplest, Namiki / Ogura will deliver an off-the-shelf catalog design cantilever of the kinds that are published in their documentation or websites. Altering... 
Lyra Lambda Atlas/Etna
@rauliruegas , I am aware of the VTF and impedance sensitivity of the F1. I was given 845 ohms as the impedance target, so that is what I used (Vishay metal-foil resistors). Overall I didn't find it unusually sensitive to setup, simply that it had... 
Lyra Lambda Atlas/Etna
@mijostyn , as long as the "loosened tolerances" are not due to damage, they should remain within the range of adjustment by the cartridge builder, and it therefore it should be possible to rectify the issues if the manufacturer accepts cartridge ... 
Lyra Lambda Atlas/Etna
FWIW, I have had the Formula One in my system for a few weeks. It's an excellent cartridge, it not only measures well, the attractive sonic signature makes it easy to recommend (other than that the low output may be a bit of a challenge for some p... 
Lyra Lambda Atlas/Etna
The Proteus has 0.28mV@5cm_sec output voltage with coil impedance of 1 ohm, and is therefore more comparable to the SL versions of the Atlas and Etna (0.25mV@5cm_sec output voltage, coil impedance of 1.5 ohm) than the standard (0.56 mV@5 cm/sec. o... 
SUT Advice - Which Ones Are The Best?
@lewm , @mijostyn was undoubtedly trying to be helpful by linking to a page where a transformer winder (Sowter in this case) provides primary inductance data for one of their designs.In addition to the Sowter Type 1990 webpage https://www.sowter.c... 
Measuring "Stylus Drag" with the RPM Speed and Wow app
According to the article "Cutting LPs, the Theory" published in Studio Sound 1975-07, "The frictional force acting on the stylus point pulls the stylus point in the direction of the groove motion with a force of about 25% of the playing weight (tr... 
SUT Advice - Which Ones Are The Best?
It is sometimes said that an SUT should be matched to the cartridge (or the other way around).The reason typically given is the need to have an appropriate amount of SUT gain to bring the cartridge's output up to a level that is comfortable for th...
