MARCH Audio P262 Purifi Class D HiFi Stereo Power Amplifier

  

One of the best sounding amplifiers regardless of price based on state of art Purifi Class D Amp module and it is made in Australia by March Audio with top quality parts throughout. The chassis is solid aluminium milled and it is just gorgeous looking and touching. It is only 8 months old and condition is absolutely Mint and works perfectly. The P262 is a Purifi based stereo power amplifier. This simply elegant product is milled from solid aluminium with a tough anodized treatment.

Exceptional finish and build quality. Featuring the stunning Purifi class D technology developed by Bruno Putzeys, the P262 delivers extraordinary low noise and distortion with sublime subjective audio quality. Exceptionally clean and neutral sound with deep tight bass and extended sweet high frequencies. It delicately reveals the smallest of details in the recording.

PURIFI's continuing research into nonlinear control theory has produced the first mathematically exact large signal model of self-oscillating amplifier controllers. This breakthrough allows complete optimization of the feedback circuit and improves performance by at least an order of magnitude over existing implementations. The amplifier module further incorporates a comprehensive protection system that makes it tremendously robust. The class leading technical performance delivers a neutral but captivating musical sound that will suit the finest partnering equipment.

Fully 2 ohm capable with ultra low output impedance, the P262 can deliver up to 265 watts into 4 ohms and 25 Amps ensuring tremendous grip and drive even with challenging speaker loads. The differential (balanced) input buffer has been designed to extract the maximum performance from the Purifi module, minimise noise and eliminate ground loops. Featuring Neutrik XLR / TRS combo input connectors, 4 layer circuit board, OPA1612 op amps and very low noise LT3045/94 voltage regulators. Input gain can be selected via a rear panel switch for optimal signal to noise ratio depending upon whether your source is RCA or XLR.

The balanced XLR input is fully compatible with RCA sources by using an adaptor cable. "Your input buffer is more transparent than our Eval1 board". The new main power supply is custom designed and a significant improvement over the Hypex unit seen elsewhere. It has very low noise with high current output and excellent voltage regulation.

Efficiency is improved with power factor correction. The ETI Research Kryo speaker posts are manufactured from Tellurium Copper with Silver plating for superior conductivity and long lasting durability. 2 Ohms - 430 W rms? 4 Ohms - 265 W rms. 8 Ohms - 135 W rms.
