When you inspect a JX amplifier, you will see that nothing is spent on gimmicks, blue lights or chrome. Instead, you'll see specified oversized output transistors and rugged MOSFET power supplies that ensure ample current and thermal capacity. These beefy parts operate well under their limits to deliver stable performance and significantly more reliability than the wimpy devices commonly found in many competing products. All of these components add up to solid bass definition and cleaner, louder high frequency output that gets the most out of your speaker system.
