anyone hear Leif Series or LS Nordost IC cables

Hi,

I am thinking of comparing some IC cables to use running my EAR phono preamp to my Dartzeel line stage preamp. I have tried a silver interconnect but that was not a good match. I was thinking of trying perhaps the newer Nordost Leif Series aka LS because it is supposed to have better bass than the older Nordost cables.

Has anyone heard the blue heaven ls or red dawn ls?

thanks

Michael
