Groneberg cable good?

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.

Ive had mixed results with the quattro. Did no care for them on the front end but are critical between my Odyssey pre amp and amp. Tried several brands of ICs in this position but none could duplicate the synergy that the quattros create between the two odysseys.
