The road to VPS100 took many turns in our long and extensive

evaluation of topologies, 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 600 Ohms.

 

A few manufacturers are using LCR based phono stages using variations of the original TANGO LCR circuit. The challenge in 600

Ohm 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 50-500 Hz poles and the

second T filter forms the 2123 Hz pole.

 

In the VPS100 we took it one step further, the 2123 Hz pole is

formed by air core inductor with practically no stray capacitance

at the first gain stage and the 50-500 Hz 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 aluminium sub

chassis that forms together with the aluminium bottom plate a

very rigid platform.

Stereophile Class A+ Component:


"The Ypsilon produced an absolutely intoxicating blend of

stupefyingly extended high frequencies, resolution, clarity, and

transient precision, along with tight, deep, nimble, nonmechancial bass, and an ideally rich-ie, not too rich-midrange with just the

right amounts of body and harmonic structure".

 

"I heard the high-frequency clarity, air, and extension of the best

solid-state phono preamps, as well as the harmonic expression and musical flow of the best tube phono preamps, with none of the

negatives of either".
