Some folks don’t have the budget to buy good equipment, while others don’t have the time to spend trying to figure out how to use it. BasX components combine great sound quality, a carefully chosen set of genuinely useful features, and rock solid performance, with a simple yet elegant design.
The BasX offers all the essential features that make a great audio component. The circuitry in the BasX A-500 features a heavy duty linear power supply, great sounding high-current short signal path Class A/B amplifier modules, a trigger input and output, and industry standard unbalanced audio inputs. It also includes audiophile-quality fault protection that’s completely transparent in normal operation, yet protects the A-500 and your other equipment from common fault conditions.
The BasX A-500 delivers real audiophile sound quality – and we’ve got the specs to back that up: 110 watts RMS per channel at less than 0.1% THD into 8 ohms (two channels driven); THD+N of less than 0.02%; and a signal to noise ratio of 120 dB referenced to full power.
While the BasX A-500 offers lots of performance, you won’t need a Ph.D. to install and use it. Just plug the BasX A-500 into any standard 115 VAC or 230 VAC line; it will figure out the correct voltage to use. A removable heavy-duty power cable is included, and, if you want to experiment with power cords, the BasX A-500 also accepts any industry standard IEC power cable. The speaker outputs are heavy duty five-way insulated binding posts that work equally well with bare wire, banana plugs, or spade lugs.
The BasX A-500 is built to last, with a heavy duty steel chassis, solid milled aluminum faceplate, and high-quality parts and construction… We expect you to enjoy your BasX A-500 for a long time – and we back that up with a full three-year warranty.

Heavy duty insulated five-way speaker binding posts - allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs.
Remote trigger input and output - allow the BasX A-5175 to be turned on by trigger-enabled equipment, and to activate other trigger-enabled equipment.
Audiophile-grade fault protection - entirely transparent under normal conditions, yet protects the amp and your other equipment from all common fault conditions.
Universal AC line voltage operation - the BasX A-5175 is designed to operate on either 115 VAC or 230 VAC at 50/60 Hz, and automatically detect and configure themselves to operate with your local line voltage.
Standard IEC power inlet - fits all standard and audiophile IEC power cables.
Three-year warranty - ensures that you’ll be able to enjoy your BasX power amp for years to come.
The BasX A-5175 is a five channel power amplifier. The BasX A-700 combines classical audiophile amplifier architecture - based on a heavy-duty linear power supply, and a carefully designed high current, short signal path, Class A/B output stage, with advanced, microprocessor-controlled monitoring and protection circuitry, to deliver superb sound quality at a truly reasonable price.
