I decided to replace the 49 cent hair-thin, plastic molded IC's on the vintage rig in the 70's mancave. Just wanted something of more substantial build--but cheap. Went to Monoprice.com and ordered 2 sets of their 6ft "premium" interconnects, at a whopping $3.23/each (product # 2864).
The premium features RG-59 wire, thick insulation, and nice gold plated connectors--hard to believe their making any money on these things at the price. Not expecting much, they surprised me by taming an overly "zippy" treble, and seem to squeeze a little more bass foundation. Impressive for such a cheap cable. The HPM's sound far smoother now, and less in-your-face.
Give them a look if your wanting an inexpensive alternative to the cheapies included with your equipment.
