Know before you buy
This hybrid approach allows the amplifier to operate in pure Class-A for low-level signals up to 10W, providing the warmth and detail associated with Class-A, while switching to Class-AB for higher power demands to maintain efficiency and control.
Yes, the HQS 7001 is designed specifically for demanding loads. It delivers 300W into 8 ohms, scaling up to 850W into 2 ohms, ensuring it maintains composure and authority even with difficult speaker impedance curves.
The hard-wired cable is a deliberate design choice to eliminate potential contact resistance and interference points found in standard IEC connectors. This ensures a more consistent power delivery and superior noise rejection for the internal circuitry.
By eliminating intermediate connectors between the output stage and the binding posts, JMF Audio reduces signal degradation and impedance. This direct path ensures the signal remains as pure as possible from the amplifier to your speakers.
The modular architecture is primarily designed for professional maintainability and long-term serviceability. It allows JMF Audio to perform updates or repairs efficiently, ensuring the amplifier remains a reliable component in your system for many years.
The HQS 7001 features balanced XLR inputs, so it is best paired with a preamplifier that offers high-quality balanced outputs. This configuration maximizes the amplifier's interference rejection capabilities.
