RT-3 Pre Amplifiers
This new Flagship Preamplifier is an upgraded version of the quite stunning RT-2 (All Silver version of the RT-1)
This is a minimalist in operation, but no effort spared, quite over the top, nothing to degrade the audio Preamp. The power supply is a lot bigger than used in most large output amplifiers. The combined units weigh 56kG.
This preamp sets a new standard in sound quality. Superior to the already stunning RT-1 and RT-2.
Price: Please contact us for pricing on this special product.
The Silver version uses a square section pure silver, 24 carrot gold wiring in all crucial signal paths and in the umbilical cord from the power supply.
This quite substantial Preamplifier is an upgraded version of the quite stunning AM RT-2, which evolved from the Stereo Knight Magnetic Enigma Silver.
This is a minimalist in operation, but no effort spared, quite over the top, nothing to degrade the audio, everything previously learned Preamp.
It was needed to to drive AM's Crowning Glory. The Nothing spared, whatever it takes to achieve the absolute in music reproduction. The AM 833S Silver Edition Monoblocks.
It is a stunning piece of design and engineering. The multi selector 33 step volume pots are painstakingly constructed in house for the ultimate in quality. Many years of research and development has gone into these pots. They operate multiple windings on transformers, which are also constructed in house, and give the first level of amplification, the same as the extremely impressive R-S Transformer passive preamp. This then drives the nothing compromised, nothing spared tube amplifier section, with a simply humongous power supply weighing about 25kG. The monstrous transformers have a bandwidth exceeding 15hZ to 122KhZ.
The Preamplifier works in Pure Class A, Single Ended mode using two 6H30 as the drivers, two 6922 valves as the amplifiers.
The preamp is a dual mono design, so that the transformers, power supply and voltage regulation are completely separated, so avoiding noise and cross talk. They use a large number of high value U-Cap copper foil capacitors, which were carefully chosen for their natural, analytical sound. The output transformers bandwidth can extend to between 15 HZ to 120KHZ
The design of the new tube preamp is quite unique. The name "Magnetic AM R-T1" can be implied from the prefix: "magnetic", which indicates its direct origin from the AM magnetic passive preamp. Not only does the AM R-T1 utilise transformers for volume attenuation, but also another 2 transformers for the signal output and two more for power supplies.
The remarkable level of performance has been achieved with an all new audio and power supply circuit design. This new audio circuit is all tube, Class-A, with zero feedback, utilising a total of four long-life tubes (2 6H30 as the drivers and 2 6922 as the amplifiers); and furthermore, it is a truly balanced circuit design in both the input and output stage, with the support of 2 volume control transformers.
The Magnetic R-TI is a direct upgrade from the AM reference version of the magnetic passive preamp, which already delivers an exceptional performance, by utilising both tube amplifiers and output transformers. One great advantage of this magnetic feature is that it is capability of optimally matching with any amps and interconnects, while accepting input from any sources, at various impedance levels, with the least possible interference to the signal.
The power supply is divided into two separate parts: The main power transformer, which is used to power the audio circuit, and Mosfets, that are used for both the voltage stabilisation and for a constant current supply. This enhances the reliability, and makes the tube amplification as linear as possible.
With its great build quality, very carefully selected audiophile grade components, versatility and the ability to musically transform every system, not only does the AM R-T3 deliver striking clarity and detail that presents instrumental timbres and textures in an unmatched amazingly lifelike way, but it also represents great value and great reliability.

As soon as I walked into your room at the Show, I knew I had found the sound quality that I have been looking for a long time. I got sick of buying expensive equipment that just didn't do it, so I spent a ridiculous amount of money on what was supposed to be the best. As soon as you connected your AM 833M that I had heard at the Show, to my system in place of my $150,000 Mono-blocks, I could not believe that big an improvement was possible, so my first thought was "What are the big ones like? When you bought them down I only had to listen to one track to know that these were never going to leave here. So I had to hear the RT-s against my much more expensive English Pre. It was the same difference. Noiw when I sit down to listen, I just can't stop. Thank you.
