Audioquest Blizzard vs Audioquest Hurricane Source

Hi, I was wondering if anyone compare these two on a preamp?
I tried the Blizzard and the Thunder on my preamp and preferred the Blizzard.
The Thunder gave some edginess in the highs...
I suppose it is because the Thunder uses Lgc and psc copper where the Blizzard uses psc plus only...
Hence my question about the Hurricane source vs Blizzard, both use only psc plus, the best copper version...
