Lyra Helikon SL-Worth upgrade?

I don't know either. My dealer, whom I have come to trust, says that the upgrade would be worthwhile. He also told me once that the difference between the clavis d.c. and the parnassis d.c. was pretty close. A matter of taste or sonic signature?
I have tried the frog and liked it very much. I was very impressed. I liked the clavis d.c. more, but I got the impression that most would prefer the frog.
Come to think of it, the clavis d.c. is a fairly idiosyncrate cartridge. It can have a tendancy to sound thin, and undynamic, compared to other super carts, which it trades for super detail. Of this I am sure of.
I think in a situation like this a dealer that can laon you a heliken or provide a demonstration would be invalueable.
I am highly curious. Evan from these answers above I am still guessing wheather it is somewhat a matter of taste or a no-brainer.

The Helikon is a great step forward from the Clavis. Except during the first break-in period, it is much more full bodied and has decidedly more PRAT, here being closer to the Insider than any other cartridge I am familiar with.

Why don't you look at the Arkiv B? The Helikon and the Arkiv share the same designer, and the Arkiv is purpose built for your analog system.

Put my in your book and have had a Clavis DC for over four years now and the silly thing will not wear out. It is in a Rockport Capella table and maybe it is the vacuum hold down or whatever that has kept it together all these years, but never got more than eight months out of a VdH.....Have two friends who have Helikons, but not the SL version and one of them replaced the Clavis DC with the Helikon and thought it was a nice improvement. The other friend had a Clearaudio Accurate and found the Helikon more to his liking.....They both run Rockport tables.

Rcump, had the same experience as you with the Grasshoppers.
