''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... 
Cartridges with that musical coherence - having heard it, I need to learn more
While cartridges are important, their tracking ability, tonal balance, naturalness, dynamics, pitch definition etc. all can be hugely affected by the choice of tonearm (and phono stage, and setup).Due to the above, I recommend to @markusthenaimnut... 
Audio Technica AT 666 vacuum disc
I don't have much hands-on experience (only at shows and an audio shop or two), but here are two similar products made today:http://www.i-teqx.co.jp/top/vacuum.pdfhttps://www.yukimu-officialsite.com/cvs-1kind regards, jonathan 
Stylus Wear Question
@stringreen Have you thought about contacting the cartridge manufacturer?A manufacturer that values customer service should be willing to tell you how much wear has accumulated on a stylus, and readjust the suspension if the cantilever shows signs... 
Who needs a Diamond Cantilever...? 💍
Hi @edgewear:>The auction ended yesterday at a smidgen under 200.000 JPY and I’m happy to disclose that my Japanese contact has won it!<200,000 JPY is quite a bargain. Today Namiki-Adamant charges significantly more for their top diamond can... 
Who needs a Diamond Cantilever...? 💍

LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING
@jeffvegas My advice is to not even think about the Kleos until it can be made clear why the Delos isn't performing in your system.If you spend even more money, and the bottleneck persists, you will be really upset (smile).kind regards, jonathan 
LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING
@tomic601 Sorry I don't think I have seen your communication; or if I did I must have failed to follow up on it.Could I ask you to resend it?If you use the title "Delos and Triplanar" for example, it should be easy to search for it.
