  • Chord SPM 5000 MKII....... 560W Reference Power Amplifier

    The SPM 5000 MkII is our range-topping stereo power amplifier and our most powerful stereo amplifier to date. Featuring double-height dimensions, the amp was conceived due to demand for a larger stereo power amplifier. Using the latest low-distortion amplifier circuitry with our own proprietary lateral structure dual-die MOSFETs, naturally, the SPM5000 Mk II is able to drive extremely difficult loudspeaker loads with clarity and precision.

    It offers a substantial 560 watts into 8 ohms and is comfortable driving larger loudspeakers, including those with challenging loads. Now in MkII form, numerous engineering refinements have been made to increase its sonic performance, flexibility and lifespan.

    The flagship stereo power amp contains two of our 4kW high-frequency switch-mode power supplies with our unique dynamic coupling techniques. Like its amplification siblings, the technology is complemented by a large bank of energy-storage capacitors that are ‘recharged’ by the power supply, giving the amplifier huge reserves of headroom. Unobtrusive protection circuitry constantly monitors the amplifier status and magnetic current-sensing will shut down the SPM 5000 Mk II in the event of a short circuit.

    Balanced and unbalanced connections are available along with two pairs of loudspeaker outputs with gold-plated connections.

  • Audio Research Ref160M "The best amplifier in the world"

    Every now and then one gets the privilege of being in custody of something that is a work of absolute beauty and performance ... having a pair of these on demonstration is the High Fidelity equivalent of a violinist being rendered with a Stradivarius by a patron.

    Putting them into the Sonus faber Aida 2 system immediately bought the musicians into the room ... I have a particular opera recording that was sold in by Hartleys in Melbourne in 1957 that I procured in a lost corner of a curio store from a deceased estate. Playing this with these amplifiers Puccini and la Boheme were born again in the space ... time travel is a reality with a system like this ... yes we cried a little.

  • Chord SPM1400 MKII Mono Power Amplifier (Each)

    With Chord Electronics Limited’s considerable experience in the design and manufacture of the world’s best consumer and professional amplifiers, we are proud to announce our latest design of power amplifier utilising our high frequency power supply techniques and our own proprietary lateral structure dual-die MOSFETs. This amplifier provides all the benefits of mono amplification whilst retaining all of the much loved qualities of Chord Electronics amplifiers. Improvements in capacitor technology have boosted secondary reservoir levels to 94,000 µF storing over 381 Joules of energy. A “Superamp” in all but dimensions, this amplifier is for those whose goal is direct comparison between live and recorded music, a sentiment echoed by reviewer and customers alike.

    Hi-Fi News magazine recently praised the latest-generation SPM 1400MkII mono power amp in its September 2013 edition. The issue features an in-depth review of our new mono power amp and sums up by saying: “Beautiful to behold by both eye and ear, Chord’s MkII SPM 1400 monoblocks offer spectacular insight into music. Majoring on clarity, timing and delivering natural realism like few other power amps at any price, they tick every box in the audiophile hi-fi check list. Neutral, detailed and with breathtaking resolution.” Hi-Fi News gave the ‘1400MkII their ‘Highly Commended’ award. You can download the full review below.

    A high current mains filter ensures that the amplifier is shielded from disturbed mains as well as ensuring that the mains is untouched by emissions from the amplifier. The output from the power supply uses a truly innovative “Dynamic Coupling” technique whereby the positive and negative rails are mutually coupled by a strong magnetic flux. The result being that if a high demand is put on one rail, the energy required is actually drawn equally from both rails. This keeps the amplifier balanced dynamically and the reference point perfectly clean.

  • Audio Research Reference 75 SE Power Amplifier ... take me home

    Our Nicks' absolute favourite product of all time, a product he says he would struggle to ever part with. Tattslotto or not.

    To sing its praises higher again, even the reviewer from Stereophile wouldnt let it leave his system. As quoted below.

    "John Atkinson has said that there is no greater praise a reviewer can give a component than to purchase it for use in his own reference system. And although I loved my time with the Reference 75, and felt it equaled or exceeded the performance of my Reference 110 overall, I still love my Ref 110. With the decline of the financial-services industry in the recent meltdown, I'm earning a fraction of what I did 10 years ago, even as I have one child beginning college this year and another not far behind. I can't justify the luxury of purchasing a new stereo amplifier this year."

    "The hell with it. I'm buying the Audio Research Reference 75"
