Purifi Eigentakt Technology

Featuring the stunning Purifi class D technology developed by Bruno Putzeys, the P801 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 with a warmth that engages the soul.

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 and protects your speakers.

The class leading technical performance delivers a captivating musical sound that will suit the finest partnering equipment. Fully stable with loads right down to zero ohms, the massive 40 amp current and power output capability ensuring tremendous grip and drive even with the most insensitive and challenging of speaker loads. It has load invariant performance.  The state of the art low noise and distortion make it the perfect amp for the most demanding of applications and audiophiles.

The P801 amplifier can deliver up to 1400 Watts into 2 ohms at an incredibly low 0.1% distortion.

Being a monoblock, all forms of crosstalk are eliminated.  The oversized power supply provides an extremely stable and low noise foundation which never gets strained.  Also, very importantly, the mono block format allows the amplifier to placed right next to the speaker and the use of short as possible speaker cables eliminating their colouration.  Its a far better solution to use long interconnects and short speaker cables.

Unique Input Stage

Our new “Ultra” input buffer has been designed to extract the maximum performance from the Purifi 1ET9040BA module, minimise noise and eliminate ground loops. Featuring Neutrik XLR  input connectors, 4 layer circuit board, OPA1612 op amps and very low noise LT3045/94 voltage regulators. The unique buffer topology provides remarkably low levels of noise and distortion that our competitors just cant match. Troublesome RF signals are effectively filtered at the input. High and low 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. Note that amps which fit RCA connectors on the chassis do not solve the ground loop problem inherent to RCA.

Custom Power Supply

The new main power supply is custom designed and a significant improvement over the Hypex unit used by other manufacturers. Our PSU features very low noise with high current output.  Active synchronous rectification means it has excellent voltage regulation and doesn’t suffer from bus pumping. Efficiency is improved with power factor correction. This means higher power output and lower noise and distortion than our competitors can achieve using the off the shelf Hypex PSU. The outdated Hypex supplies will only drive the Purifi 1ET9040BA module to around 1100 watts short term.

Quality Components

The highest quality components are used throughout.  Top tier capacitors from the likes of Elna and Rubycon. ETI Research Link speaker posts are manufactured from Tellurium Copper with gold plating for superior conductivity and long lasting durability. Canare and Mogami cabling ensure internal signals are transported with absolute integrity.

 

Reviews

Simple looking black boxes they may be, but March Audio’s P801 power amps can deliver 1400W each into 2 ohms — which makes them a steal at the price.

Reliability

Hand built and individually tested, the P801 is backed up with a 5 year warranty. This can be extended to 10 years.
