I have Sigma rca ICs and PCs in my system. I like the sound a lot...organic, lovely midrange and treble, tight and tuneful bass, very quiet. Putting just the Sigma ICs in caused the soundstage to completely disconnect from the speakers and move out into the room. Very noticeable.
I use the Sigma XLR digital cable and I think that it is the best sounding digital cable I've heard in my system. My comparison points are the earlier Shunyata Anaconda/Python digital cables.
I haven't used other brands for a long time as I've been moving up the Shunyata line.
I have found SR products to be excellent (black boxes, FEQ, HFT, etc.), but the only cable I have from them is a REL spec reference subwoofer cable, which is also excellent (tho' expensive).
I have Transparent Ref SC and have thought about auditioning Sigma SCs, but I really don't want the expense right now...'cuz I know I'll probably buy them.
