SET - 100 MKIII amplifier
$ 93,000

SET 100 is a SE hybrid amplifier of 2 gain stages, output power of 120 Wrms with low enough output impedance.(0,5 Ohm)
It has the magic midrange of a small S.E.T amplifier with the scale, authority, macro and micro detail, that no amplifier has ever achieved until now.
It uses a specially designed s-e mosfet output stage. SET 100 has power and drive with transparency, musical involvement and above all with music sounding naturally.
With only 2 gain stages in the signal path, the level of immediacy, transparency is unequaled by designs using more than 2 gain stages.
Having no overall feedback, the distortion is kept comparably low while the output impedance is sufficient enough to drive real world loudspeakers.
The first stage is a high trans conductance triode selected for its sonic capabilities and reliability. It is powered by a separate power supply with tube rectification and choke regulation.

SET 100 is an amplifier that produces music in its true natural scale, but above all it brings you as close as possible to the music event, to feel the music rather than hear it, to be touched and overwhelmed by the deeper feeling, with music emerging and not only sounding in a clear undistorted way.
Compared with conventional amplifiers it is more direct sounding, musical, with more instrument body , lower frequency extension, frightening dynamics and most of all magically three dimensional.

Its strong point is that in large orchestra crescendos it sounds transparent and totally unstressed until it reaches full power.

In the MKII version several upgrades have been made.The input stage tube now used is the NOS 5842 type which is a high gain single triode. The copper foil paper in oil inter stage capacitor has been removed and also the first and second output stage is now direct coupled through a sophisticated and simple technique. The bias of the output stage has been changed and now is done from the first stage. Also a bigger and lower noise power supply transformer has been developed and is now lying behind the casing of the SET-100.

SET-100 VS single-ended amplifier.
$56,000

Our aim in designing the VS (Valve Stereo) was to produce an all valve single-ended amplifier with 3 gain stages and output power of 40Wrms that would correctly capture the magic of a single-ended design and that would also be capable of driving even the most difficult speakers. This design specification was considered not only important but vital to the credibility of the amplifier. Since the majority of single-ended amplifiers from other manufacturers produce between 2 to 15 watts and require highly efficient speakers (>100db sensitivity) in order that realistic volume levels can be achieved, Ypsilon were determined that power output would not limit the versatility of their amplifier. The VS also has two sets of output taps, separately for 4 and 8 ohm speakers which further increases its appeal.

After a great deal of evaluation, Ypsilon decided to use the GM70 valve which they found to be not only very linear and capable of at least 40 Wrms but also wonderful sounding.

The Ypsilon VS uses the same chassis as its bigger brother the SET-100 which only uses materials of the highest quality. The VS will surprise you because its sound is so far removed from the flabby base and overly warm presentation of traditional SETs. Everything is in proportion without any emphasis of any particular frequency range and the music it presents has a beautiful flow to it; and it most certainly does not seek to beat the listener’s ears into submission in an attempt to convince. The VS ticks all the boxes in the checklist of hifi desirables, but that is to miss the point. The VS was designed to move the listener.

PST - 100 pre amplifier MK II
$37,000 In stock for home audion please call

Most manufacturers develop a circuit for their power amplifier and then use the design for their preamplifier. The raison d’etre of a power amplifier is to amplify the signal and drive the loudspeakers. That of a line preamplifier is to draw together the various source components; to attenuate the signal in order to achieve "volume control"; to have low enough output impedance in order to drive the cables; and finally, to provide gain if it is required. It performs totally different duties to those of a power amplifier and needs to be designed in a totally different manner.

Conventional wisdom suggests that the most critical part of a preamplifier is the active circuit design. Ypsilon, however, believe that the means of signal attenuation (the volume control) is the most critical to the overall sound of a preamplifier. Most designers use resistor attenuators for volume control. Ypsilon themselves have used resistor attenuators with high quality resistors (Vishay, Holco, tantalum types etc.) in the past, but that was before they developed a very special transformer as the means of attenuation. It was immediately apparent just how grainy and discontinuous resistors sound, even the best of them. The short explanation of this observation is that the series resistor transforms the constant voltage into current and the parallel resistor the constant current into voltage. The materials used in resistors are far from ideal as conductors- they sound much worse than pure copper or silver- and they do a lot of harm to the signal.
In a transformer, however, the magnetic circuit can be ultra linear when the very best core materials are used. The sound of such materials is much more musical and detailed compared with the best resistors. So Ypsilon produced, in-house, a special transformer attenuator with 31 taps.

The active gain stage is a no - feedback s.e. ,C3m triode, transformer coupled. The power supply uses valve rectification(using the 6CA4) and choke filter. Wiring is point to point with custom made pure silver wire. The transformer attenuator is placed after the valve stage, preserving the purity and micro details of the signal.
The maximum attenuation is 52db and maximum gain is 16db. Output impedance is 150 Ω max. PST is the pinnacle in preamplification. It is a must have component for building a "no holds" system.

VPS - 100 phono stage
$26,000

The road to VPS-100 took many turns in our long and extensive evaluation of topologies and materials, design and implementation.

Passive RIAA equalization is preferred to active because in active RIAA equalization
there is a feedback loop and the RIAA network is in this feedback loop.

Usually RIAA equalizer circuits are implemented with capacitors and resistors (CR networks). Capacitors present the so called "dielectric absorption" -energy is stored in the dielectric material and is added to the signal with a small delay producing a ringing character in fundamental notes. This ringing behavior can be noticed in piano notes.
In the past an alternative way of implementing a RIAA equalizer the LCR (Inductance-capacitance-resistance) circuit was proposed.
A long time ago TANGO transformers from Japan used to produce such a circuit working in 600Ohms.
A few manufacturers are using LCR based phono stages using variations of the original TANGO LCR circuit. The challenge in 600ohm LCR eq is to drive the network properly; having no more than 2 gain stages with enough overall gain and low enough output impedance.
The best way of driving the LCR network is by using a transformer. We design and build ourselves the transformers using a special amorphous c-core material. Winding insulation is paper. A properly implemented LCR RIAA sounds much more natural, musical and open than CR networks with better defined macro and micro dynamics.

The LCR networks most commonly used are based in double T filter networks .One T filter forms the 50-500Hz poles and the second T filter forms the 2123Hz pole.

In the VPS-100 we took it one step further, the 2123Hz pole is formed by air core inductor with practically no stray capacitance at the first gain stage and the 50-500Hz poles are formed in high signal level directly at the output of the second gain stage. So this is a split RIAA design using two gain stages based on the SIEMENS C3g tube. These tubes are very reliable as they are specified for 10.000 hours.

The power supply uses the 6CA4 tube rectifier and a choke filter .The heaters for the tubes are AC in the second stage and DC passive regulated for the first stage. The construction uses no printed circuit boards and is point to point silver wired using our own extruded and annealed to spec silver wire. Special attention is paid to mechanically de-couple the first gain stage and 2123 pole coils using a specially designed decoupling system.
The rest of the construction is mounted on a aluminum sub chassis that forms together with the aluminum bottom plate a very rigid platform.

The MC series moving coil step-up transformers are used to amplify the low level output signal from a moving coil cartridge bringing it to the appropriate level to drive a moving magnet phono preamp.

When terminated in 47k which is the standard input impedance of MM phono preamps the equivalent input impedance of each one would be: MC10 500 ohm / MC16 200 ohm / MC20 140 ohm.

If additional loading is needed, it can be done through the parallel input RCA connectors.

The MC series transformers are large size single C-core double coil transformers using a proprietary amorphous core material. Special winding techniques were developed in order to minimize inter-winding capacitances and maintain wide frequency response. They are optimized sonically to be as invisible as possible.

The transformers are shielded with mu-metal and are potted in 10mm thick soft iron nickel coated enclosures providing immunity to outside magnetic fields and a quiet and noise free performance.

The MC transformers were developed in conjunction with the Ypsilon VPS100 phono preamp. They can be used with most of the moving coil cartridges. For optimum performance the MC transformers can be used within a specific range of cartridge output levels.

MC10 for cartridges from 0.4 - 0.6mv / 20 db gain
MC16 for cartridges from 0.3 - 0.4mv / 24 db gain
MC20 for cartridges from 0.2 - 0.3mv / 26 db gain

CDT - 100 cd player
$26,000

CDT -100 is YPSILON’s top loader cd player/transport. The transport’s primal objective is to retrieve data from the cd-disc with as much accuracy as possible. The laser head is extremely sensitive to vibrations so CDT-100 provides a rigid and resonant free construction.

The mechanism is mechanically modified and assembled within a massive construction of a sandwich of thick stainless steel and aluminum plates. In this way, the traditional box shaped chassis is avoided and along with that the associated resonance problems are greatly reduced. The result is a solid, coherent construction that in combination with the
suspension system provides vibration free operation.

The CDT 100 is a stand-alone product which will outperform many highly regarded separate Transport and Dac combinations. It carries a Spdif out put so it can be linked to any outboard DAC. But for ultimate performance, which will astonish all who encounter the combination, then via the 5 pin output to the Ypsilon DAC-100. Truly, a world class combination.
CDT-100 contains a non oversampling DAC , with multi bit Burr Brown dac chips.Power supply regulation for the dac is only with shunt regulators.

The current output of the DAC chips is level shifted in the current domain and through an in house manufactured c-core transformer becomes a voltage signal directly at the nextgen output connectors. No feedback is used and only one low noise S-E class A jfet is involved in the signal path. Purity and transparency is the result,so when inserted in a SET system then one can fully appreciate the full sonic glory.
CDT-100 provides 3 outputs.

-One SPDIF 75 Ω next gen connector.

-One pair of RCA , analog connections , for use as a CD player.

-One Neutric 5-pin analog current output for use with DAC-100.

We strongly recommend the use of the 5-pin output with DAC-100 for optimum performance. It is our belief that transmitting audio in the digital domain (SPDIF),even discrete such as I2S format, has its imperfections and adds a certain character to the sound. The frequency of bit clock and data bit is too high for transferring the signal in a transparent way.

DAC - 100
$29,000

DAC 100 is our D to A converter. It is a non - oversampling, no upsampling design with multi - bit dac chips. The carefully designed power supply is with shunt regulators. I / V conversion is done by a specially designed, built in house, transformer. Τhe analog stage uses single-ended class A transformer coupled triodes with valve rectification and choke regulation .
The valves are the high mu, high trans conductance, low noise SIEMENS C3g NOS tubes.

There are two available inputs:

- SPDIF coaxial 75 Ω with next gen connector.
This input can be used with CDT - 100 or other high quality transports.

-One Neutric 5 - pin analog current input.

When this input is used with CDT-100 the digital part of the dac is disabled and is powered off. Only the analog section is used. With CDT-100 we strongly recommend the use of this input for optimum performance.
The conclusion has been reached that by using this 5-pin connector the signal is transferred to the analogue section of the DAC-100 at an absolute optimum sonic capacity avoiding all the limitations of digital interfacing.

All transformers are designed and built in house using the best available materials and are wound with sophisticated techniques for a totally transparent sound.
The transformers are of enormous size in order to achieve the absolute performance we seek.
We believe that DAC - 100 reaches the limits of digital reproduction and can be compared only with the best analogue sources.
The DAC-100 D/A converter is also 24bit/192Khz capable used in high resolution digital sources.

BC 1
BALANCED CONVERTER TRANSFORMERS
$3,700 pair

Product Features
The Ypsilon BC1 transformers are used for converting an unbalanced signal to a balanced one. They can be used with any kind of unbalanced source like cd-players, phono preamps, line preamps etc. They can also be used for breaking ground loops in a system, lowering the total noise floor and improving the interface between equipment by providing galvanic isolation.

Each BC1 Transformer has Two inputs, One RCA Nextgen connector and One female XLR Neutrik connector with pin 1 and pin 3 grounded. The output connector is a XLR male Neutrik connector. Pin 1 is the center tap of the secondary coil that is connected at Pin 2 and 3 respectively. Pin 2 or pin 3 therefore should not be connected to ground.

The BC1 transformers use a proprietary high performance Cobalt based amorphous core material of very high permeability that is very linear with frequency and flux level. This specific material is regarded to be one of the best magnetic materials available today.

The BC1 transformers are optimized sonically to be as transparent as possible. In this way they can improve the performance of a system since they provide a better interface isolation between devices. The signal ground current doesn’t travel through mains chords but only through the interconnect cables, maximizing in this way the overall performance of the system.

The BC1 transformers are shielded with mu-metal and potted in 10mm soft iron with a nickel coating. Outside magnetic field interference is kept to a minimum.
