Who needs a Diamond Cantilever...? 💍
Hi @edgewear Yoshihisa Mori was close friends with Kanemori Takai, and after Mori left Sony, he was involved in a variety of projects, one of which would have been the creation of a cartridge production line inside Final.FWIW, Final was originally... 
LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING
Please, let's not dump on @jeffvegas . Audio is a hobby, with the analog field being particularly so. There is nothing wrong with having strong opinions and personal preferences.I would much rather have an audiophile who prefers MMs or MIs over MC... 
LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING
@jeffvegas Even small changes in tracking force should alter the sound of the Delos quite a bit, which suggests that your current setup has not managed to extract all of the performance that the Delos has to offer.Nonetheless, I wish you the best ... 
Tracking error or ??
The easiest way to conceptualize the 4point bearing is as two knife edges (one for horizontal movement, one for vertical movement) with the center sections removed. Since there are only two points left as contacts at the extreme outsides of the kn... 
LYRA DELOS CARTRIDGE TOO BRIGHT, THIN AND SHRILL SOUNDING
@jeffvegasIf the Delos hasn't been modified or retipped by a non-Lyra company, and you suspect that there may be something wrong with it, you are welcome to send it back to us (Lyra) via the dealer that you purchased the cartridge from, so that we... 
Opinions wanted on cantilever alignment
Hi rushfan71: I haven't received any email from you, but your photos suggest that one of the asymmetrical (IOW pointed or tapered) dampers in the suspension system has rotated away from where it should be, and the cantilever is being pushed away f... 
Who needs a Diamond Cantilever...? 💍
Hi, and hope that everyone is staying safe!Note that the auction listing on Yahoo.jp <https://page.auctions.yahoo.co.jp/jp/auction/b489057356> is for the integrated headshell version, with a long joint pipe and comparatively short diamond st... 
Why do most phono preamps lack XLR input even thought cartridges are naturally balanced?
Phono cartridges are floating sources rather than balanced, and unless there is a low-impedance connection between phono amplifier ground and both sides of the cartridge signal coil, and/or the common mode rejection of the phono stage input stage ... 
Cartridges: Kuzma CAR or Lyra on a 4-Point (11") arm
Hi @hamburger : Most likely the Delos suspension is still intact, but has stretched a bit and needs a readjustment to bring the ride height back to what it should be.If you would like us to take a look at your Delos and readjust it if necessary, p... 
What about diamond cantilever/stylus combo
It is with deep regret that I must announce the departure of a true giant. Yoshihisa Mori passed away on Dec. 26, at the age of 77. His numerous accomplishments at Grace, and subsequently Sony (SACD as well as phono cartridges) are a testament to ... 
FR66s vs Ikeda IT-407 CR tonearms
It is with deep regret that I must convey the sad news that Osamu Ikeda passed away at the age of 92, on 2018-09-17, Japan time.He contributed to analog audio in a manner that few can emulate, and will be sorely missed.The Ikeda brand continues, i... 
Highest detail cartridges
Certainly @chaksterDenon's DL-1000A MC cartridge had an effective tip mass of 0.077mg.https://www.denon.jp/jp/museum/products/dl1000a.htmlEven their lower-priced DL-305 got down to 0.168mg.These cartridges (as well as Technics 205, 305, 100) were ... 
Cartridge Loading- Low output M/C
May I ask what low output MC cartridge has 5ohm and 5mH? The 5ohms is representative enough, but 5mH is a few decimal places larger than I would expect.http://www.whatsbestforum.com/showthread.php?15077-Cartridge-Loading-A-Misnomer&p=258578&am...

Phono Preamps with "balls" ?
>There is a real bipolar " problem " against FETs and is that you need perfect matched devices<As I wrote earlier, the JFET matching issue can easily be addressed by measuring and sorting. This requires extra work and organization on the par...
