Just to be clear for future readers, the clickrepair software also features the ability to remove surface noise, hiss and other issues caused by wear and physical damage, although it is a lossy process overall. The click removal portion was the least important component in the restoration, as there are good number of software and hardware solutions that are decently effective. The use of a number of different stylus types and profiles also aided in the process to capture a cleaner source file achieving a better quality, more listenable, product.

Or -- just don't let the records get dirty in the first place. Failing that -- a good ultrasonic record cleaning machine can perform miracles.

Agreed, just maintain your collection. If you have an LP that is in bad shape replace it.

The Boston Audio Society had their monthly Zoom meeting on Sunday with the guest speaker Peter Ledermann of Soundsmith. He was also formerly chief engineer at Bozak so before the meeting started there were some good discussions about Rudy Bozak and his speakers. He went into great depth about cartridges and the physical characteristics that contribute to the sound. Of particular interest was the moving mass problems with different generator designs such as MC, MM, and MI. His down to earth approach about the necessary tradeoffs was interesting.

A considerable time was spent on cantilever design and the effects of different materials and construction. Another item of interest was the effect of different stylus shapes on riding on different parts of the groove walls that can result in better sound when playing a record where the groove walls were damaged by a different shape. For example, a large conical stylus will damage a section of the groove higher up than a line contact stylus. Switching to a line stylus will allow tracking in a lower, hopefully less damaged part of the groove. You will have to make sure to submit the record to a thorough cleaning to get the schmutz out of the lower part of the groove for that to be effective. Altogether a good meeting.

If you want a great education on everything Analogue (in relation to cartridges)
