System Setups
RCA vs. XLR
You see shiny, thick cables labeled "XLR" and standard, smaller cables labeled "RCA." Do you need to buy the expensive ones? The short answer is: It depends on your system and your ears.
Your first HiFi
You don't need a brand-new $600 integrated amplifier. Look for older Home Theater Receivers (AVRs) from the late 90s and early 2000s.
