My speaker set is a JBL600 6.1 package; was like $400 back in '03; 6 satellites and 1 powered sub. They sounded good; but now they sound even better.
I’m going to just slowly upgrade soon piece by piece; probably all pro-audio amps; a high-end receiver/pre-amp, and custom speakers.
The amp that I’m using now as of tonight is a Behringer EP2500; basically a clone of the QSC RMX series.
