This is an ambitious high end single brand system that throws down the gauntlet from Japan to the rest of the World. Needless to say Yamaha have the resources to pull something like this off. Although the elements of the 5000 are firmly based on the iconic NS1000 loudspeakers and the turntable pre and power amplifiers of the time, this system is thoroughly representative of third decade 21st century materials and design.

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.

350W of serious power amplification. This unit is not only a work of industrial art, it's everything and more than what you'd expect in terms of grip, control and musicality.

I've been pleasantly surprised with the new versions of Chord Electronics Pre and Power combinations. I found many of their previous models of stereo power amps harsh and brittle but this is different - this sings. 

This is a must listen if you're looking for a beefy power amplifier.

It has had some stellar reviews, unsurprisingly and it's no wonder that there were lots of Chord Power amplifiers powering speakers at the latest Munich HiFi show earlier this year.

This brand new NAP 250 is something to behold! Fast and pacey with extra ordinary bass response. I had a customer ask me twice whether I was sure there weren't any subwoofers attached to the system.

We've had this playing for a couple of days on a set of Spendor D9.2s along with the matching Naim NSC 222 and NPX 300 and it is a standout. Crisp, fresh, pace and rythym.

We just put it on some Sonus Faber Guarneri Homage speakers and we think it may be a match made in HiFi Heaven.

Naim products bought from us, a genuine approved Naim dealer, include the full 2 year warranty.

The new M8-700m monobloc power amp is fully balanced, and offers a staggering 700 watts per monobloc, with stellar sound quality and technical performance.

The M8-700m has extremely low distortion, typically 0.001% at 1 kHz. At 20 kHz distortion is still below 0.005%. Distortion at 50 kHz (a ridiculous and unreasonable measurement, but revealing of the total amplifier performance nonetheless) is 0.02%. At 100 kHz, it is about 0.06%. These extraordinary measurements, and the extremely low high-frequency distortion, are highly significant sonically.

The noise ratio of the M8-700m is extremely low at -120 dB A-weighted.

The M8-700m has huge power reserves, producing 700 watts RMS into 8 ohms and just on 1300 watts into 4 ohms. It is an absolute powerhouse.

The power, low distortion and the extremely low noise contribute to its fabulous, effortless sound.
