Lyra Helikon

According to the people at Scantech, there is no sonic difference between the low and high output versions of this cartridge. Having said this, the main difference is fewer windings on the coils, hence lower moving mass for the coil assembly. One might conclude that this would increase speed and low level detail.

Every cartridge manufacturer claims that the Hi output version of a cartridge is the same quality as the low output version. If that were really true, they'd only put out a high output version. Common sense usually triumphs over hype.

I agree. Go with the low output version. The lower, the better, provided that you have a phono stage which is up to the task.
