The nxV500 is designed as a very high performace, high end audio amplifier in the Recording Studio's, Audiophile Amplifier's, Home Theatre and Sub-Woofer Amplifier's

The nxV500 has XLR Balanced inputs as standard and it can be configured for RCA single ended input as well.

The performance of this amplifier is truely awesome and unlike a lot of amplifiers these days. The power ratings are continuously rated sine wave into a resistive load.

The HPA-nxV500 amplifier module now has a world wide fan base and it has been shown from extensive listening tests from around the world that this amplifier module rivals even the best sounding and most expensive amplifiers in the world regardless of price. Based on this the HPA-nxV500 represents extremely great value for money.

For the not so budget minded.

Here is what you will need to build a Stereo HPA-nxV500 Amp.
