Western Electric 300B with Large Hashimoto output transformers > nanoat@yahoo.com
Our amplifiers sound as good as they look , a number of colour options.
Welcome to the new wave of High End audio design at Nano Audio Technology - Nano AT ™
registered with ASIC AU .
In these days of mass produced Amplifiers from a Plethora of Auction sites ,many with cheap components mounted on printed circuit boards ,we offer a hand made series of tube Amplifiers with Audiophile grade parts, featuring point to point wiring , inferior printed circuit boards are not used in the main signal path .
As a builder of Bespoke High end class A amplifiers , we are able to source the best output transformers using exotic metal and multifilar winding techniques , some are rarely seen in mainstream audio manufacture , Printed Circuit Boards are not used in the main body of the amplifier as they compromise sound quality compared to point to point hand wired builds .
We manufacture hand crafted Single Ended and Push Pull Amplifiers in Australia, ranging from 4 watts to 40 watts.
Excellence in build quality and sound reproduction is paramount in all we do.
Different chassis finishes are available , natural wood with orange oil and hand rubbed shellac or black gloss and polished alloy top plates .
Each and every component chosen has to earn its place in our line of tube amplifiers.
Naturalness of presentation, accuracy of tonal balance within a large and open sound stage feature in all our designs.
An even handed balance across the whole audio spectrum.
Detail is crystal clear with good solid bass ,they have a beguiling naturalness to their sound as if the musicians were in the room with you.
The Natural timber and nuances of the original recording are very lifelike.
Our output transformers are of the highest quality sourced mainly from USA and Japan .
Teramoto Finemet ® is our top of the range, other choices are explained under the more tab.
Power supplies are Toroidal for low noise and ultra quiet operation with tube rectification.
We offer traditional tube rectifiers or the latest SS IXYS HiPerFRED ultra path supply design we call "the super smooth "
which eliminates any audio path through the power supply.
The Push Pull amplifiers have Nickel Core Fi/Ne Permalloy phase splitting transformers and a choice of output transformers.
Our traditional chassis has 5mm alloy CNC cut top and bottom plates .
The centre piece is Baltic Birch Ply, again CNC cut which provides a very attractive surround and a vibration proof platform all in one .
The audio tubes we supply are generally new old stock .
For improving performance and manufacturing quality, NanoAT reserves the right to make changes in specifications and parts without prior notice.

Quote SOUND STAGE AUSTRALIA
"In one of my favourite rooms – I came back several times to this oasis – Australia’s Nano Audio Technology’s debuting and lovingly-bespoke 300B- and 6A3-based amplifiers were alternately valve-caressing either Contrast Audio or Wyndham Audio (also Australian) speakers. Brinkmann’s Bardot turntable !
Our parts are sourced locally and overseas, mainly Japan,USA and the UK.
Designs and parts are subject to change from time to time.
Each Amplifier is Appliance tested and tagged to Australian Standards and the power supply transformers are CE certified .
