Power Amplifiers

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.

Available for Demo. This wonderful power amplifier has Audio Research's proprietary auto-bias circuit which adjusts for tube wear. The new VT80SE is Audio research's much-anticipated entirely new entry point power amplifier combining an enticing new esthetic with worry-free operation and great audio performance, the VT80SE is a vacuum-tube amplifier that will open doors to a new customer base.

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.

Only a rare handful of power amplifiers withstand the test of time. The BHK Signature 300 is one such amplifier. Hand built, uncompromising. Learn More

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.

This replaces the much loved Reference 75 ... now with the Ghost Meter display and the minimal signal path circuitry that characterises thius new range.. It's a beautiful thing.

The Audio Research Reference 80S stereo amplifier continues Audio Research’s latest design effort in creating a vacuum-tube amplifier that not only redefines ultimate music reproduction, but does it in an incredibly beautiful package. Learn More

The Evolution of the Ref 160Ms, the Ref 160M MkII have an upgraded audio topology with fewer and better components in the signal path. This means even less chance of corruption of the signal for a cleaner, more pure, more musical sound.

The difference is quite marked between the old and the new. The MkII version sounds more Audio Research than the previous model. Audio Reseach is all about purity of sound and getting to the real music of the recording without corruptions. That's why they are an all tube company now because they feel that tubes do this best. That's why the MkIIs are more Audio Research because they exhibit more clarity, more purity than the older version.

Like all Audio Research, these are handmade in Minnesotta, USA. From design to polish, it's all done in house with the utmost care and attention to detail. All in the pursuit of the ultimate musical experience. 

Priced each.

Now on demonstration this is the much awaited successor to the Ref 150 and incorporates the revisions that made the Ref 160 mono blocks the "best amplifier in the world".

This Stereo version uses the same four layer circuit boards that dramatically decreased the signal length in the 160M monoblocks. It has been described as like buying a pair of 160Ms but just buying one and getting the second for an extra twenty percent ...

With eight KT150 valves inside ... and not just any KT150 but a group of specially made and selected and matched ... this has the option of Ultralinear or Triode modes of operation.

Ultralinear gives double the power apparently while triode offers the simplest circuit mode possible with lower power and sweeter sound.

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.
