Seven Phono Stage

Seven Phono Stage

The Seven phono is the first point of entry into the world of Tron phono amplifiers and is used to increase the musical output from your cartridge and to balance the frequency response to the correct RIAA standards, then present a low impedance output to drive your preamplifier or main amplifier. The phono stage is a critical and highly sensitive part of the analogue amplification stage and I have worked over a long period of time to produce a consistently musical and tactile experience treating the delicate musical output from the cartridge with care and respect. I have kept the stages in the Seven phono to an absolute minimum, which is key to maintaining the integrity of the dynamics of such a small signal source and have selected valves/tubes (3 in total) that are both musically open and also easily obtainable so long term listening pleasure with be insured. The Seven phono can be supplied setup for either moving magnet or moving coil cartridges to suit your personal choice. The challenge to deliver truly stunning results from a low output moving coil, and maintain a low noise floor have been worth it, and the moment you place the stylus into the record groove this will become obvious.

Seven Reference Phono Stage
The Seven Phono stage can be upgraded to the Reference specification to further improve the musical performance from your valuable record collection. Graham painstakingly sources truly unique resistors that in such a simple circuit really bring out a richer and more intimate performance from the artist. We also upgraded the capacitors to a custom specification to work in harmony with the improved resistors; as in most development activities changing one thing in isolation hardly ever results in a balanced improvement. Graham says "it never ceases to amaze me how improving one component can impact the music in such a significant way, and also how long it takes to find the right combination to retain true harmony."

Seven Ultimate Phono Stage
The Ultimate is the penultimate step towards analogue perfection, and involves the use of solid silver wiring throughout the critical signal path, and silver MC transformers. Silver as a conductor has the advantage of a more revealing and transparent reproduction of the music, however care needs to be taken to ensure that this is delivered in a complete and unified manner as sections of silver in a component in isolation rarely provide a benefit. Finding the right dielectric (insulation) for the cables is also critical to extract the best from this expensive material. Graham has also redesigned and built a more significant power supply that is unique to audio, which has the effect of making silences darker and dynamic shifts in the music more dramatic. The result is a little like cleaning your windows; you did not necessarily notice they were blocking any light, until afterwards.

Seven GT Phono Stage
The Seven GT is the final step towards analogue perfection, and involves the use of a completely new power supply circuit for all the critical stages. Graham says this power supply was 5 years in the making and makes a huge improvement in fidelity taking the Seven GT to one of the finest phono amplifiers ever made.

Seven Mono Phono Stage

Seven Mono Phono Stage

The Seven Mono phono stage has been made available so audiophiles can enjoy their collection of mono recordings with the maximum fidelity that only a specifically designed mono phono stage can offer.
Note: the image shows two Mono Sevens being used as a stereo phono stage.

Why a mono phono stage?
Pre-1957 record companies used different recording equalisations prior to the introduction of the RIAA standard. We have developed this phono stage to allow more faithful reproduction of these early recordings. The Seven is equipped with three switchable equalisations which the owner can specify during the order process.

Modern mono cartridges often do not work well with stereo phono stages, noise and gain are the biggest problems. This is because stereo phono stages are designed and constructed to receive a stereo signal rather than a mono signal.
If you have heard a true high fidelity mono recording through a Seven Mono phono stage you will notice the sheer immediacy and dynamics that prevails. Many TRON customers actively seek out mono recordings as they are addicted to the unique sound that can be achieved.

To see and hear a stereo/mono demonstration please click this link 

 

 

Features

The Seven Mono phono stage can be specified with 48dB, 68dB and 74dB of gain (overall gain), or a custom MC gain setting can be accommodated at time of ordering.

Seven Line Stage

The Seven Line is a new design with many unique features built over a long development timeline is search of the most musically satisfying experience. Like all TRON products it relies on the vacuum tube for amplification. We have kept the stages in the Seven to an absolute minimum and have selected valves/tubes that are musically transparent and rich, but also easily obtainable, giving the potential owner the option of using his or her favourite brand, we can advise here on how this affects the musical performance subtly.

 

Features

The Seven line stage comes with 5 RCA inputs, mono/stereo switch, mute switch, earth lift switch, silver RCA sockets, non ferrous case and it is all made in the UK. It also has fitted a very high quality Elma selector switch and a close tolerance Noble volume control. The current build of the Seven Line Stage now also features a tape loop.
The output stage is a very low impedance high current design, which enables it to be used with any power amplifier, whether transistor or valve.
The Seven line stage provides up to +15dB of gain.

Specification:
Inputs: 5 RCA Line inputs (L & R).
Outputs: 2 RCA main output (L & R) & 1 RCA tape output (L & R).
Valve Complement: 2 × 5687 (low noise).

Seven Preamplifier

Seven Preamplifier

Graham has developed a superb little phono stage to partner the Seven line stage resulting in the Seven preamplifier. This is a new design with many unique features built over a long development timeline is search of the most musically satisfying experience. Like all TRON products it relies on the vacuum tube for amplification. We have kept the stages in the Seven to an absolute minimum and have selected valves/tubes that are musically transparent and rich, but also easily obtainable, giving the potential owner the option of using his or her favourite brand, we can advise here on how this affects the musical performance subtly.

 

Features

The Seven Pre comes with 4 line level RCA inputs, a phono input for vinyl replay and a tape loop, as well as the mono/stereo switch, mute switch, earth lift switch, silver RCA sockets and non ferrous case like the Seven Phono and Line. Of course this too is made in the UK. It also has fitted a very high quality Elma selector switch and a close tolerance Noble volume control.
The phono stage featured in the Seven Pre is a brand new design and can be ordered as either MM (48dB gain), MC (68dB) or MC high gain for use with low output cartridges, with 74dB gain. This is is configurable at time of ordering.
The Seven Pre's line stage, being identical to the stand-alone Seven Line, provides up to +15dB of gain. The output stage is a very low impedance high current design, which enables it to be used with any power amplifier, whether transistor or valve. Additional partitioning has been employed internally to help reduce the disruptive effect of magnetic, mechanical and electrical fields for the critical aspects of the circuit. Note: All Sevens can be specified with 20dB, 26dB or a custom MC gain setting at time of ordering.

Syren II Preamplifier

Syren II Preamplifier

It is just so easy to loose the nuances at the first stage of the amplification and this has driven Graham to work so meticulously on the Syren as a personal project. Graham handcrafts each Syren as an act of passion, which takes him nearly 2 weeks full time (over 70 hours of skilled labour). Probably the most difficult stage of amplification in any system is the first as it is dealing with the most sensitive signal, anything lost at this point will disappear forever. The preamplifier has the primary responsibility of preserving the music signal where the key is to maximise the dynamics and minimise any corruption, which will be magnified further down the signal path. Graham's designs are by their very nature simple and concise, using the shortest possible signal path. A circuit board is used in preference to hard wiring because, when executed properly, it is more effective in reducing noise, resulting in a quieter background allowing more musical information to be heard. As with most things it all comes down to the quality and the execution. All circuit boards are not equal; Tron uses 1.6mm thick rigid boards that help stabilise micro resonances. The tracks are made of very high purity copper and elegantly laid out to minimise the length of the signal path.

The Syren is designed using four carefully divided partitions. These partitions help reduce the disruptive effect of magnetic, mechanical and electrical fields for the critical aspects of the circuit. All the components are oriented spatially to limit interference, and are of the highest quality available. Most are specially made to order and the strip core transformers and chokes are individually hand wound. This guarantees perfect pitch, rich tonal colour, and exposes the subtle timing and harmonic structure of the music, where lesser components corrupt and compress the signal. If you listen to a violin up very close then you can literally hear the harmonious chorus of every tiny resonance, and it is precisely this rich textural musical signature that we are passionate about preserving in combination with the timing and dynamics of the performance, in essence, to deliver the emotion of the music.

Phono stage can be specified with the following levels of gain:
1) +69dB for cartridges with an output of 0.3mV to 0.7mV.
2) +75dB for cartridges with an output of 0.1mV to 0.3mV.
3) Up to +89dB depending on customers cartridge.
Any of these options can be specified during the ordering process.

Reference
The Syren II can be upgraded to the Reference specification to further improve the musical performance from all your musical sources. The output transformers form a critical stage in the amplification and to further improve the Syren II we have specially developed some unique non-standard core material that we keep as proprietary knowledge and simply refer to as exotic. These exotic core transformers help to lift the musical performance and enhance the vibrancy and intimacy of the music, in a way that just makes everything sound more immediate and tactile. We have been a little surprised, but delighted with how much a change in the core of a transformer can make to the musical performance, and this is why we have spent so long perfecting the materials we use in our exotic cores. Making these in such small quantities has also proved a challenge from some aspects of our sourcing, however we believe it has all been worth it.

Ultimate
The Ultimate comes with all the additions of the Reference model, but also uses 99.99% pure solid silver wiring throughout the critical signal path. Silver as a conductor has the advantage of a more revealing and transparent reproduction of the music, however care needs to be taken to ensure that this is delivered in a complete and unified manner as sections of silver in a component in isolation rarely provide a benefit. Finding the right dielectric (insulation) for the cables is also critical to extract the best from this expensive material. Our choice of dielectric enables the ‘skin effect’ associated with incompatible insulation to be rendered almost non existent. This helps to bring the music to a tighter and more cohesive performance, here conventional cables tend to render the small details essential for the whole piece to really hang together in a muddled and incongruent way.

GT
GT Specification is the final step to perfection and to achieve this we have redesigned and build a more significant power supply that is housed in a completely separate box, matching the Syren II enclosure. The layout puts the power supply in it’s own housing, which allows us to place the components in their perfect orientation, and to shield the stages from cross interference. We have also wired the entire unit with 99.99% pure silver wire to be absolutely certain that the maximum possible performance is achieved. This has the effect of making silences darker and dynamic shifts in the music even more dramatic, and with a good recording this is phenomenal. Graham has described the improvements with the power supply as a little like cleaning your windows: You did not necessarily notice they were blocking any light, until afterwards. Well this power supply is like opening the French doors and looking straight out into the sunshine!

Voyager

Voyager

The Tron Voyager is a unique and very special amplifier, and has been a personal project for Graham for many years; as the concept of an OTA circuit he found both intriguing and challenging. It is a true OTA (One Tube per channel Amplifier). There are only three valves in the whole amplifier: one output valve per channel for audio and a rectifier valve in the power supply.

The Voyager is the simplest of amplifiers made today, it is the closest you can get to the theoretically perfect "wire with gain". Simplicity is both an opportunity and a challenge; if you listen to a chorus of voices all merging into a coherent sound then one or two imperfections are lost in the shadow of the whole. Whereas a closely micro-phoned solo performance is totally exposed and naked, there is simply nowhere to hide, every imperfection or aberration is noticed. The OTA with such a simple circuit is the same and Graham has spent many nights working into the small hours listening and adjusting to get the whole to work as one. In the words of Graham “every tiny change affects the tone, personality and colour of the performance, and with such a simple circuit you can literally hear the differences in the solder types used. It has been incredibly frustrating, but ultimately so rewarding to find the perfect balance for the circuit. I have never learned so much in one project as I have with the OTA, and I named the amplifier the Voyager in recognition of this”

Model Options

Reference
The Voyager can also be upgraded to the Reference specification to further improve the musical performance from all your musical sources. The output transformers form a critical stage in the amplification and in a power amplifier drive the output to the speakers. Ensuring that we maximise this element is critical and so to further improve the voyager we have specially developed some unique non-standard core material that we keep as proprietary knowledge and simply refer to as exotic. These exotic core transformers help to lift the musical performance and enhance the vibrancy and intimacy of the music, in a way that just makes everything sound more immediate and tactile. We also see the use of these cores in the output transformers for the power amplifiers delivering a greater sense of control and power of grip over the speakers; the effect is more like a speaker upgrade than an amplifier.

Ultimate
The Ultimate comes with all the additions of the Reference model, but also uses 99.99% pure solid silver wiring throughout the critical signal path. Silver as a conductor has the advantage of a more revealing and transparent reproduction of the music, however care needs to be taken to ensure that this is delivered in a complete and unified manner as sections of silver in a component in isolation rarely provide a benefit. Finding the right dielectric (insulation) for the cables is also critical to extract the best from this expensive material. Our choice of dielectric enables the ‘skin effect’ associated with incompatible insulation to be rendered almost non existent. This helps to bring the music to a tighter and more cohesive performance, here conventional cables tend to render the small details essential for the whole piece to really hang together in a muddled and incongruent way.

GT
GT Specification is the final step to perfection and to achieve this we have redesigned and built a more significant power supply that is carefully laid out in the existing chassis. This layout is very labour intensive to install but allows me to place the components in their perfect orientation. We have developed specifically designed capacitors for the circuit as readily available samples were not able to maximise the circuit Graham had been working on. We have also wired the whole of the power supply with 99.99% pure silver wire to be absolutely certain that the maximum performance possible is achieved. This has the effect of making silences darker and dynamic shifts in the music even more dramatic, and with a good recording this is phenomenal. I would describe this improvement by making the analogy to film photography; a good print film can have rich beautiful colours and a great tonal range, but when you compare it to a great slide film the depth and richness of the picture just takes your breath away.
