Gran Prix Audio w/F1 shelves & GPA footers w/nitride balls. But only IF the the three elastomer pads per shelf are replaced every six months or so.
Don't have room to list them in my ownership listing at bottom of each page. I like them because they are by far the most musically involving racks I have heard. Others can and do change/improve the sound. The GPA opens the doors and invites you into the music. IMO...
How much do these elastomers cost? Also Jim, which other racks/isolation techniques did you try before the GPA, for both electronics and TT? Thanks
