My budget rig was built around Grado's, kinda wish I would of done a few things differently now, and plan on doing some upgrades when I get back working.
I use my computer as source, I bought the Headfive last year for $250, NOS Number Cruncher 203.2 for $50, and the SR80's ran me about $95. Cables: Quail power cord, Monoprice Toslink, still need to upgrade my RCA patch using an old Monster Cable MKII400.
