So, here is a snap of my rigs. the foreground of course the 846 with new quad ribbon cable on top of the new vamp verza. the hpa8 and th900 in back ground.
After some intrepidation from hearing about problems with specialty cables and mmcx connector problems with the 846, I have to say none with the quad ribbon. Snapped on great and worked from the get go. Concerning sound improvement holy smokes did these things open it up and then some. probably the most significant sound upgrade i have witnessed. The only draw back if any besides price, is the 4.5 ft length as Id prefer a bit longer at 6 ft. Other than that, the vamp and these cables has unearthed biblical upgrade in dimension, depth, and clarity. Im freaking, recommend alo quad cables without any hesitation, just do it, warm up that credit card already. So I will depart and lie back and marvel at alisa weilerstein cello sonata, cheers.
