Phono Stages
Leben RS30EQ $3800
RS-30EQ is equipped with the CR-type equalizer based on GE 12AT7, and can reproduce very high quality 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%.
- Tube compliment – JAN 12AT7A (G.E.) X 2
6X5GT (G.E.) X 1
- Gain – 23.5dB
Fosgate Signature Phono $POA
World-renowned audio engineer Jim Fosgate has been working on this design for the last thirty years. His passion for analog and tube sound led to the design of this incredible vinyl playback tool. The Fosgate Signature all-tube design has no solid-state devices in the signal path. Its switchable moving magnet/moving coil gain settings and variable loading settings make it extremely versatile.
A combination of modern design with retro appeal, this seven-tube wonder knocked us for a loop here in our reference system. The Fosgate Signature is everything you’d want from an all-tube design: warm and inviting, but with incredible frequency extension and detail retrieval.
The Fosgate’s life-like reproduction of voices and instruments give it a stunning sense of realism. This baby throws one hell of a soundstage, too. One doesn’t normally expect a product this beautiful, with sound this sumptuous, to come anywhere near this price.
Specifications:
Gain: 42dB MM, 60dB MC
Loading: 100Ω, 300Ω, 500Ω, 1kΩ, 47kΩ, 100kΩ (Selectable)
Tube compliment:

Moon 310LP $3300
The MOON 310LP represents a significant step forward in phono preamplifier design. Like its predecessor, the highly acclaimed MOON LP5.3, particular attention has again been given to noise levels and dynamic range. The result is one of the quietest phono preamplifiers ever, on par and even superior to many models at significantly higher price points. Sonically, it portrays all the Simaudio hallmarks: clean, powerful, fast and extended bass combined with an open midrange and airy extended high frequencies.
A major strength of the MOON 310LP is its highly configurable nature. There are numerous end-user adjustments for resisitance loading, capacitance loading and gain level. Going one step further, you can even chose from two different equalization curves – either the RIAA curve with a flat frequency response or the IEC curve which, although identical to the RIAA curve beyond 20Hz, acts like a subsonic filter by removing inaudible infrasonic bass below 20Hz.
Balanced outputs are a standard feature, allowing you to take full advantage of connectivity to a balanced preamplifier or integrated for a significant improvement in noise floor, dynamics and midrange transparency. Finally, the 310LP is housed in a custom-made, rigid chassis with a 3/8” brushed and anodized front panel.
Significant Design Features:
· Large isolated power supply on a separate circuit with 2 stages of voltage regulation
· adjustable impedance loading (10, 100, 470, 1K and 47kΩ)
· adjustable capacitance loading (0, 100 and 470pF)
· adjustable gain settings for moving magnet cartridges (40dB) and moving coil
cartridges (54, 60 and 66dB)
· Selectable equalization curves for both the RIAA and the IEC standards
· Optional MOON 320S external power supply upgrade
· Single-ended RCA and Balanced XLR outputs
· 4-Layer PCB’s with pure copper tracings for a much shorter signal path; This
results in greater sonic accuracy and a dramatically improved signal-to-noise ratio
· Power supply voltage regulation includes i2DCf (Independant Inductive DC Filtering);
There is one inductor dedicated to each integrated circuit type component
(DAC, Op-Amp, etc.) in the audio circuit’s signal path – 2 stages in all
· Extremely short signal path for a faster transient response
· Accurate matching of the finest high quality electronic components
· Designed to be powered up at all times for optimal performance.
Dynavector P75 $699
The Dynavector P-75 Phono Stage is a unique entry level phono stage with several outstanding features that ensures the P-75 will out perform other phono stages costing considerably more then the P-75.
The P-75 also includes the patent P E (phono enhancing) circuit designed by Dr Tominari to dramatically improve the performance of low output moving coil cartridges.
By a simple arrangement of jumper settings all conventional, MM, MI, high and low output cartridges are catered for.
The P-75 also has an advanced power supply that operates from a conventional 12V AC to DC adaptor. This adaptor has absolutely no bearing on the sound quality.
The P-75 power supply runs at over 1/4MHz. It takes the low grade single voltage DC supply from the ac adapter and converts it to the dual high voltages required for true professional quality audio reproduction. The operating frequency is over 12 times higher than the top of the audio band and it incorporates super low noise wideband regulators in its output stage to give ultra low noise supply rails. The internal P-75 power supply is totally self contained and stores many times the maximum possible energy requirements for the phono amplifiers. This means that the quality or size of the external ac adaptor is irrelevant. Increasing the capacity of the external supply will make no difference to the quality of the sound.
Like all Dynavector products the P-75 whilst innovative carries on our proud tradition of faithfulness to the heritage of phonographic recordings, exhibiting clear, full-bodied, distortion free sound that analog enthusiasts require.
Rega Fono MM$400 MC$535
The Rega Fono is a high quality discrete component moving magnet phono preamplifier. The Fono has been designed to be effective, easy to use, and above all to reproduce music with outstanding effectiveness. The aesthetic design of the Fono was as important as the quality of its electrical capabilities, so it benefits from the same aluminium case as the Rega Ear Head phone amplifier, giving it a design which offers a familiar family feel and moreover brings it in line with its illustrious bigger brothers.
Like the Rega Ear, the new Fono benefits from an all new extruded aluminium case and new styling giving it more of a family feel, to match its illustrious big brothers.
The Fono simply connects to the line input on the amplifier, and the tonearm leads and earth (if used) to the input socket and earth terminal of the Fono back panel.
Project Phonobox USB $299
Today, many amplifiers do not have a specific phono cartridge input. Phono Box USB is ideal for use with these amplifiers and allows the use of MM and MC cartridges. The output of Phonobox USB can easily be connected with a line-input, offering the additional possibility to transfer analogue audio onto PC/Mac using USB1.1 protocol. .
• Preamplifier for MM or MC with switch on the rear panel
• Low-noise ICs
• Analogue-out (RCA) & USB Digital-out
• Compatible with Windows®, MacOS® and Linux®
• Available in black and silver
