Hi everyone, I have sent emails and called and left messages for Bob Grost over a few months with no response. I did buy something and I am trying to buy another set of cables. Does anyone know what is going on? I have Matrix SCs and one Matrix IC and really like them.

I am looking for a pair of 1.5M Matrix Damping squared Interconnects with RCAs and a pair of Matrix Jumpers for speakers.



I spoke to him several weeks ago and ordered his new Interconnects. Tried one, compared it to my Shunyata sigma2, sold the sigma 2, and ordered more of his. I can’t speak for his responsiveness, but i’ve had no issues. He may be overwhelmed with a new line of speakers he’s putting out.

droleg - Which interconnect was it? Matrix or Luminscate? Was it XLR or RCA?  Thanks.

Hi everyone,

Through this forum I have found the jumpers and interconnects I was seeking.

I truly appreciate everyone's help and kindness!
