Haute Fidélité 2006
Paris, France
Audio Consulting was attending the Haute
Fidélité 2006 show together with Magavox and Madotec in
Paris from 14.10.06 to 16.10.06 at the
Olympia Hotel
Amplifiers:
Special version of the MIPA (Mains Independant Power
Amplifier) run on external 65 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.
Another amplifier used for demos was a PWM based design.
Four Hypex UCD 180 PWM amplifier modules were fed using Audio Consulting's custom power supply and allowed for bi-amping of the speakers
Chassis by Olivier Soufflet.
The line preamplifier:
It is a low impedance Silver Rock TVC kit using
a Solid State driver stage powered by batteries.
The very nice wooden cabinets for the TVC and its batteries were produced by
Olivier Soufflet
The analogue front end:
Lyra Skala cartridge, SME IV tonearm, Mitchell
Gyrodec turntable
The phono preamplifier 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.
The Silver Rock MC step up transformer for the use with MC catridges also is
available separately
Digital front ends:
We mainly used the iPAQ HP 4700 PDA with
Sandisk Extreme IV flash cards and WAV files.
About 80 tracks were available on a 4GB flash card and allowed
never to run out of choice during the show.
A portable CD player of the iRiver 550 type was also used and
both the iPAQ and the iRiver were used on 120 Ah batteries with heavy capacitive
decoupling.
Cabinets by Olivier Soufflet.
Finally, a Denon DVD 3910 was also used on a mains filter
consisting in two PM transformers in series.
The Denon DVD 3910 is a multi standard player with heavely modified power
supply and silver wire OPT's.
We used two additionnal mains isolation transformers in series(cabinet by Nasotec)
in order to maximise mains filtering on the CD player.
Speakers:


Speakers were the full range drivers from Lowther. Low pass
crossover coils were of the low DCR "Matrioshka" silver wire type.
