phono cartridge

If coils are used in speaker crossovers as low-pass filters, why don't the coils in phono preamps and in speaker motors also limit audio bandwidth? Is it because their inductance is too low to make a difference? Does impedence matching (between the cartridge and the phono preamp input) affect...

I'll start with a question about impedence in a phono cartridge. If a mm cartridge is rated at 47,000 Ohms, is that the same as the unit's "output impedence," and is that also the impedence of the coils in the unit that generate the audio signal? Please correct me if any of this is wrong. Given...

Hey guys, Are you tired of searching for "that" specific test record you need for "this" one test you want to conduct? Does going desperately through your pile of test LPs get you weird looks from your friends and family? Have you always dreamed of having that "one" test record that would...

I really don't use my TT much these days but have quite a few musician friends who are putting out vinyl along with their digital releases. Recently a musician and I compared the two formats and, of course, the digital sounded better but the vinyl didn't sound as good as it could have. I have a...

Skip to the index. After years of development we are finally launching our phono cartridge measurement library. These measurements were created using the brilliant cartridge response python script written by the legendary @scott wurcer and @JP. Information about its origins can be found in the...

Hello! When pushed all the way up in the preamp gain I am getting 14dB of noise from one of my sources, all others make nothing, zero, nada, of noise at that highest gain of the preamp. The source that has noise is connected this way: -Cartridge - Ortofon Quintet Black S (MC low output) -Tonearm...

This thread is intended to consolidate the technical discussion and further development of Scott Wurcer's frequency response measurement script to a central area. I'd like to keep this discussion about the tool rather than specific cartridges. I'll edit this and the subsequent reserved posts in...

Greetings, all! Sorry in advance if my issue has been covered before countless times; I'm a new member who just discovered this great site today: My setup is a bit odd: I have two Technics 1200s (one a MK5, and the other a brand new 1210-GR); one has an AT-VM540ML and the other an AT-VM740ML...

I missed this, sorry if it has already been posted -- I was looking for something else and ran across this article: https://www.cnet.com/news/sad-news-vinyl-lovers-shure-exits-phono-cartridge-business/
