We Are offering 1 Ypsilon VPS-100 Phono stage in near mint condition for sale.

We can also add on the MC Step Up 26L for $4500. 

We shall also offer superb offers on some Demonstration tables in store only.

This phono stage is a reference for many an audiophile. Regarded as one of the best by many true analog ultra high end customers.
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 aluminium sub chassis that forms
together with the aluminum bottom plate a very rigid platform.
