Phono Stages / Step ups
Leben RS-30EQ
Equipped with the CR-type equalizer based on GE(General Electric/USA) 12AT7 authorized by J.A.N.(Joint Army & Navy) standard of the US Army, and can reproduce a very high quality and clear sound without adding any NFB. To avoid compromising sound quality using the NFB type, one of the solutions we adapted to completely protect the sensitive CR type equalizer was to originally develop for RS-30EQ a high quality "Orient-Core" power transformer perfectly shielded to shut-down hum noise from the transformer perfectly. We have also selected the finest available high-end audio components to keep the deflection of the RIAA curve below +/-0.2%.

AcousticPlan Phonomaster
With minimalistic circuit design best sound quality is achieved without any compromise. Only one transistor is responsible for amplification of the low MC signals. Overallfeedback, differential amplification and push-pull circuits are not used. Adjustment of the MC imput impedance to the pick-up is superfluous due to the use of a current control circuit. Tubes are only installed where they are able to develop their whole range of advantages: for prevention of natural harmonic spectrum, fusion of neutrality and liveliness as well as the exceptional dynamics. One output transistor guarantees low output impedance to drive long cables without losses.
Unregulated switching power supplies avoid any kind of humming and noise. PhonoMaster is equipped with double sided printed circuit boards for tight fixing of ceramic bases and all other components.

Modwright PH9.0
We are excited to present the new PH 9.0 Tube Phono stage with on-the-fly loading and attenuation controls. Following in the footsteps and true Design DNA of the Reference PH 150, the PH 9.0 offers most of the same performance and flexibility of the PH 150 at a much lower price and smaller form factor.
The rise of interest in vinyl has led to demand for flexible, high performance phono stages to make the most of ALL of our vinyl.
We chose Lundahl MC step-up transformers, separate MM and MC inputs, compact external power supply on a long umbilical and vacuum tube design to maximize flexibility. The use of external supply, careful grounding, layout and solid engineering result in an extremely quiet tube phono stage!
The power supply is small and has no controls and may be tucked out of the way anywhere. The phono stage itself is 10“Wx10“Wx4“H. Its compact form factor allows flexible placement.
Like the PH 150, front panel controls for MM, Mute, MC input select, On-The-Fly MC loading and gain adjustment for MM and MC carts allows for easy adjustment to suit different cartridges and systems. Mono/Stereo toggles is locate on the rear panel.
Fully balanced, transformer coupled XLR outputs are available as an add cost option. The base unit has single ended RCA outputs only.
REGA ARIA Mk3
Housed within our latest half width custom designed case to give it a fresh new look and match the range are two entirely separate, high performance phono stages. One fully adjustable, dedicated moving coil and one moving magnet. Each stage is designed and engineered to maximise the potential of your vinyl system whilst remaining easy to use and set up.
Note: All Aria MK3 MC settings will be factory preset for all Rega MC cartridge models.
Technology
The Aria is an "all analogue amplifier" with no digital control circuitry. The fully aluminium case screens the internal circuit from any stray RFI signals. Our designers have avoided including any superfluous gadgets as they obstruct the signal path and degrade the sound quality. The Aria incorporates many innovative design ideas including a self-adjusting servo control to keep the MC input circuit at its optimum, compensating for any variations in ambient or operating temperature.
Both stages have their own separate input sockets and input pre-amplifier circuitry. This enabled us to design bespoke input circuitry for each cartridge type without compromise. Signal switching is performed at high level and low impedance (via relays) ensuring there is no degradation of the signal.
MC Stage Design & Features
The MC input uses parallel connected, low noise FET's (Field Effect Transistor's) configured as a compound pair. The use of FET transistors ensures there is no bias current flowing in the cartridge coil so as not to upset the delicate magnetic geometry of the cartridge. The MC input has the provision for selecting resistive input loading of 70ohms to 400ohms and capacitive loading of 1000pF to 4200pF. The input sensitivity can be changed by 6dB via the back panel.
MM Stage design & features
The MM input uses low noise, bipolar input transistors also configured as a compound pair. There are two separate power supplies for each channel and further sub-power supplies for each of the low noise input circuits. Nichicon FG electrolytic capacitors have been used in critical positions throughout the power supplies. Polypropylene capacitors have been used in the signal path and equalization networks. Discrete circuitry is used throughout the signal path ensuring full control of the circuit design.
Dynavector P75 Mk 4
A bit more pricey than it used to be, what isn’t, but it delivers sound quality that’s fully commensurate with that asking price. What’s more it’s a great partner for any cartridge not just those from the same company as the Apheta 2 proves, especially when you set it up in PE mode which is undoubtedly it’s strongest suit.
Rega Fono Mini A2D
A high quality phono pre-amplifier for use with any moving magnet cartridge. The addition of USB interface allows you to easily transfer vinyl to your PC. The Fono Mini A2D is designed to amplify the signal from a moving magnet cartridge to a suitable level for all line level inputs of an audio amplifier. The new Fono Mini A2D benefits from an extruded aluminium case and very user friendly front and back panels that make this phono pre-amplifier a very easy product to use. The Fono Mini A2D amplifier offers exceptional performance and incredible value for money and promises to be a valuable addition to any hi-fi set up
Auditorium A23 Hommage Step Up Transformer
For years Auditorium 23 has offered step-up transformers for use with Denon DL 103, Ortofon, EMT and similar cartridges. Particularly for cartridges with low impedances its important to use a specialized matching transformer rather than a generic type. The A23 SUTs are available in a standard range, and also the magnificent Hommage range. Using an EMT TSD15 with the A23 Hommage SUT is nothing short of a revelation in musicality.
Auditorium 23 step up transformers are available in three versions, two specifically for very low impedance cartridges like the Ortofon SPU and one for higher impedance cartridges like the EMT's, Denon 103, Shelter and many others.
Auditorium 23 transformers in combination with a suitable phono preamp are simply amazing. Active gain stages will never capture the flow, texture, drive and overall musicality of a top shelf transformer like the Auditorium 23.
