Neurochrome Modulus-286: 65W (8Ω); 125W (4Ω) @ <-120dB THD Composite Amplifier Module
Key features:
Note that attached picture and measurements are of the prototype. I will follow up with a more comprehensive set of measurements once the production version is in.
The production version will be Neurochrome Blue and professionally assembled in Calgary on a gold-plated PCB made in Ontario, Canada. The finished module will include aluminum mounting hardware (also made in Canada), which allows the module to be bolted directly onto a heat sink. This mounting method greatly simplifies the mechanical work for the the DIYer (only three holes needed with ±0.5 mm precision in their location).
Fully assembled modules are in stock and available for purchase here: Modulus-286: 125W power amplifier achieving -120dB (0.0001%) THD – Neurochrome
Enjoy.

Key features:
- Mono construction.
- 65/125 W into 8/4 Ω, respectively @ THD < -120 dBc.
- Tested for stability with reactive loads up to 1.0 µF || 8 Ω.
- Multi-tone IMD residual: < -100 dBV.
- Damping factor: >560 @ 1 kHz; >225 @ 20 kHz (8 Ω).
- Integrated noise (20 Hz - 20 kHz): 17 µV (A-weighted); 22 µV (unweighted) @ 20 dB gain.
- Integrated noise (20 Hz - 20 kHz): 27 µV (A-weighted); 32 µV (unweighted) @ 26 dB gain.
- Balanced input (can be connected to unbalanced sources as well).
- Default gain: 26 dB for ease of use with other HiFi components. 20 dB available upon request. Higher gain possible by a simple resistor swap.
- Four-layer PCB, fully optimized for the highest performance.
- Designed, manufactured, and assembled in Canada. All components sourced from reputable distributors (Mouser, Digikey, et al.)
- Available for pre-order within the next few days with a significant early adopter discount. Expected in stock by the end of November, 2018, at which point the into sale will end.
