The  system was run entirely powered by batteries, including the
turntable, the phono preamplifier and the power amplifier.

Amplifiers:

1. MIPA

border=0>

Special version of the MIPA (Mains Independant Power Amplifier) 
run on external 120 Ah batteries
The 30 watt /channel MIPA
(Mains Independant power Amplifier) amplifier is a battery powered solid
state design.
It uses input and output transformers, very high speed
capacitors in the power supply and the highest quality connectors from WBT and
Eichmann Technologies.
According to Audio Consulting's general philosophy,
the cabinet is made of wood (MDF) only.
High Power version featuring
120 w/channel now available.

2. SWGPA (Silver Wire Gain Power
Amplifier)

Special version of the SWGPA (Silver Wire Gain Power Amplifier) 
run on external 200 Ah batteries
This 8 watt /channel 
amplifier is a battery powered solid state design.
Voltage gain is achieved
using silver wire transformers.
It uses input, voltage gain and output
transformers, very high speed capacitors in the power supply and the highest
quality connectors from WBT and Eichmann Technologies.
According to Audio
Consulting's general philosophy, the cabinets of the reference series are made
using special wood with very attractive wooden veneers. No lacquer but organic
oils and bee wax are being used as finish. The buttons are massive Cocobolo,
hand polished, and again, no lacquer.

 Unity
gain, Solid State stage drives silver wire TVC with 10dB voltage gain in the
TVC.

The Phono preamplifiers:

1.Silver Rock Phono Reference

width=447 vspace=10 border=0>

One of the two phono preamplifiers was Audio
Consulting's Silver Rock Phono Signature , featuring 4 silver coils per channel,
one being the MC step-up transformer:
No capacitor in the signal path here,
as the RIAA is achieved using only resistors ( one in silver) and silver
coils.
Battery power supply allows for extremely low noise as many visitors
could notice.

1.Silver WireGain Phono
Amplifier

vspace=10 border=0>

Voltage gain only in tranformers : 6 silver wire transformers
achieve 75 dB of voltage gain. 
RIAA uses 3 silver coils in an R-L
topology.
Bird's eye maple/ palissander veneer on pine wood chassis for best
sound. 
Balanced version available using twice as many
transformers/coils.
We shoewed a special version with built in TVC and phase
switch.

Silver Rock MC Step up
transformer:

width=513 vspace=10 border=0>

Silver Rock MC step up transformer for the use with
MC catridges is also  available separately.
20 or 26dB of voltage gain are
achieved using very exotic magnetics and our silver wire. Cabinet is made of
natural wood and veneer.
No lacquer but only  organic bee wax.

The analogue front ends:

The "R-evolution" turntable
by Audio Consulting

This turntable is made wood only, excluding hard
woods (except for some veneers).
It is battery powered thus totally freed
from mains problems. Even the active cooling of some of the parts is battery
powered as this has a very clear impact on the sound.

The "R-M" tonearm by
Audio Consulting

vspace=10 border=0> vspace=10 border=0>

The tonearm is made of 40'000 year old swamp Kaori
and stabilized  with several layers of C37.
The only metals here are
the unipivot needle, whereas the axe and counterweight are all made of
appropriate woods.
Wiring uses AC's custom silver wire  right to the RCA
plugs in one piece.

A Technics SP10 MKII by Nasotec:

This beautiful turntable was made by Nasotec. Using
a vintage SP 10, a wooden plinth was added and a totally independant massive
brass tonarm base was bearing an SME V tomearm.
The
cartridge was a Lyra Parnassus.

Digital front end and its mains
filter:

Denon DVD 3910 multi standard player with heavely modified power
supply and silver wire OPT's.
This mod is available separately  for your
Denon player and may be get from Nasotec.
Nasotec also uses a LClock XO3 from
LC Audio Technology.
We  used two additionnal mains isolation transformers in
series(cabinet by Nasotec) in order to maximise mains filtering on the CD
player.
Wooden lenses from Arbelos Elektroakustik were installed under the CD
player.

Speakers:

Speakers were the Dulcets by Mantra Sound from
Italy.
100dB/w/m efficency out of a very clever horn based design

Various:

The beautiful stands used under all AC and Nasotec devices, as
well as very  clever isolation technologies came from "Hifi stay", a very active
Seoul based company.
