JMF Audio HQS 6002 Dual-Mono Amplifier

Driving the loudspeakers... Caring for the music...

The JMF Audio HQS power amplifiers have been acclaimed for their high output power combined with a faithful, natural rendering of music. Since 1988, the most influential audio professionals, such as American studio designer Tom Hidley, and world-class studios (Nashville, New-York, London, Capri, Tokyo, Moscow, Toulouse, Paris...) have trusted the HQS power amplifiers to monitor the quality of the recordings and productions, with great pleasure of listening. 

While it first met with success in the studios, the JMF Audio technology was humbly aimed at celebrating music, for all music lovers. Jean-Marie Fusilier designed and built the HQS power amplifiers without the preconceptions, the marketing considerations, the deadlines or budgets that generally limit commercial designs. Jean-Marie Fusilier took up the challenge to design a high output power amplifier offering superb musicality. 

The philosophy behind the JMF Audio HQS power amplifiers can be summarized as follows: 

> A huge reserve of energy for instant delivery at the output on fortissimo. Achieved with the proprietary RPS concept involving bespoke toroidal transformers and bespoke high performance capacitors.

> High voltage electronics for superior headroom and higher efficiency. A linear amplification by design, a short signal path starting with a precision trimmed balanced input stage. These are key features of the LDA driver board, the center piece.  

> High current output capability for best possible control, allowing the amplification structure not to rely on compensations such as feedback loops, yet featuring a high damping factor by nature. The base of the proprietary MTP concept.

Key features:

  • RPS high stability power supplies. Specifically made to measure capacitors and toroidal transformers.
  • LDA symmetrical, linear and direct amplification structure (featuring PGP gold).
  • DCS servo, direct coupling, no capacitor link on the amplification path.
  • DPO direct output design: naturally stable amplification design requiring no output inductance.
  • MTP output stage: multiple transistors, individually controlled, 330A capability for HQS9001.
  • TRB temperature regulated circuits (with quick thermal stabilization starting from revision C)
  • PGP specific gold plated analog audio boards (LDA amplification an MTP output stage).
  • SCD sealed case design (no dust can enter), passive cooling (option silent heatsink cooling fan)
  • Ultra low noise floor (and cross talk on stereo version).
  • LSS made to measure dia. 6mm output terminals (120A rated) with specific PGP gold.
  • Automatic detection and protection against input offset, too high frequency, high temperature, overload.
  • Vu meter for input signal magnitude monitoring (switchable starting from revision F).
  • Hand wired, soldered and mounted. Drastic control and selection of all components.
  • All models feature the same voltage gain, which definitely facilitates multi amplifiers setups (active setups).
  • All power amplifiers are upgradable to the last revision (starting from revision B, new chassis).
