Groneberg cable good?


I am using my 1990's audio quest Quartz and topaz cables still. 

Would new new groneberg quattro ref rca's be noticeable sound improvement. There over 200 bucks with the wet connectors.  Or stick with th audio quest Quartz cables. ?

I used the Groneburgs for  few months , OK nothing more .
Cheapest Audio Anylasis and AudioArts were better .
In my system with McIntosh electronics, the Gronebergs are the clear winner compared to MIT, audio art, Kimber and Monster.
I tried the Teo GCs and didn't think they were better than my TS Premiums but am testing the HFC CT-1 now against them.
So the TS Premium sound meatier than the CT-1. They also sound a little bigger in image size. The CT-1 may be a little sweeter sounding in the mids or sparklier.
