A powerful, lightweight, high-performance rack-mountable power amp made with the professional guitarist in mind: the ISP Technologies Stealth Pro Power Amplifier.The STEALTH PRO POWER AMPLIFIER is based on ISP Technologies new patent pending "Power Factor" and "Dynamic Adaptive Amplifier Technology", and is the only power amplifier technology capable of delivering this level of output power with a 19 volt DC power pack.
The ISP Technologies STEALTH PRO POWER AMPLIFIER with optional ears for rack mounting is the first True Professional, high power floor mount guitar power amplifier delivering performance on par with the best guitar amplifiers of the day. The STEALTH is based on analog class A/B amplifier design for excellent sonic and saturated clipping performance, not found with Class D power amplifiers and will exceed the stringent tone characteristics of the professional guitarist. The STEALTH PRO POWER AMPLIFIER can be used for high SPL gigs and professional stage use. The STEALTH PRO POWER AMPLIFIER is powered from an external 19 volt DC switch-mode power adapter like that used with a laptop but will deliver a TRUE 180 watts RMS continuous output power into an 8 ohm speaker cabinet and greater than 120 volts bridged output voltage swing. The STEALTH PRO POWER AMPLIFIER can also be used as a stereo 2x 80 watt amplifier @ 4 ohms. The STEALTH can power a single 4 x 12 cabinet with incredible SPL volume level output or will power two cabinets in a true stereo rig. This incredibly small package will deliver more power to a speaker than the typical 100-watt guitar amplifier, and will easily interface with any guitar floor system or high performance pedal board. The STEALTH PRO POWER AMPLIFIER with 180 watts of power weighs in at only 1.2 pounds, adding new meaning to light weight guitar systems. The STEALTH also delivers amazing efficiency and it includes internal protection against shorts, open circuits and wrong impedance loads. An internal "power on/off" output control circuit provides pop free operation for turn on and turn off. The STEALTH's small package size of 9 inches long, 4 inches wide and 2 inches tall allows it to fit with any floor mounted pedal rig.

Comments about Isp Technologies Stealth Pro 180-Watt Power Amplifier:
I bought this in store and returned it the following day, and here's why:
It just wasn't powerful enough to stay clean at high volumes when in competition with another guitar player, bass and hard hitting drummer playing hardcore.
I had it bridged into a 16ohm 4-12 and had the level to 3oclock , Tight Metal Pro level also at around 3 o'clock and was still struggling.
It just didn't have the oooommmph in the bottom end as well.
I really wanted it to work, as it would have made for a great fly rig, but it just wasn't there.
