By far, my most significant system upgrade!

Sorry Jeff Smith!
LPs that were truly unlistenable are now, not transformed into great recordings, but highly listenable. Inner detail and musical tone is now beautiful giving breath and depth formerly hidden.
And good recordings are now spooky good and breathtaking.
Surely, everything in a system is important and adds to the performance. But Filelium speaker cables doubled the perceived value of my system.

Also please note that the bi wires are $175 not $275!Jeff has created an innovative kind of jumper that, in a loop, connects to both sets of binding posts instead of a jumper that connects to one pair of binding posts and jumps to the second pair.
This seem like such a simple and obvious fix. But Jeff is the first to think of it and offer such a reasonable and logical improvement.
