"On his Neurochrome Audio website Tom Christiansen describes and offers solid-state and vacuum tube power amplifier designs, circuit boards and construction plans for DIY. Power levels are well suited to my LX series speaker designs.
Specifications are excellent but I have no listening experience with such low levels of distortion. My requirements usually stop when harmonic distortion is <0.01%, damping factor >20 and associated power supplies are able to deliver adequate voltage or current peaks for high level transients. Most importantly, the amplifier must not go into spurious oscillation, or DC output generation, or other misbehavior when internally voltage or current clipping. My active crossover, multi-channel loudspeakers put much less demand on the individual amplifiers, than the typical n-way passive crossover speakers that are common place, because each amplifier sees a benign load made up of the speaker cable, the voice coil impedance and the motional back emf.
But still, it would be rewarding to find out that even more realism can be gained from the LX's when Neurochrome amps are used.
Ενδεικτικά ο Modulus-86 Rev. 2.0:
- Ultra-low 0.00014 % THD (38 W, 8 Ω, 1 kHz).
- Ultra-low 0.00034 % THD+N (38 W, 8 Ω, 1 kHz).
- 40+ W output power (8 Ω) when using the Power-86 and recommended transformer.
- Ideally suited for multi-channel amplification.
- Differential input with nearly 90 dB CMRR eliminates hum and ground loop issues.
- Phenomenal power supply rejection ensuring consistent, high performance even with unregulated power supplies.
- Ultra-low -120 dB inter-channel crosstalk greatly simplifies the power supply requirements.
- Elaborate use of planes and copper pours to maximize circuit performance by minimizing supply and ground impedances.
- Low-inductance signal ground connects to power ground at one point only for maximum performance.
- On-board Zobel and Thiele networks for maximum stability even with capacitive loads.
- On-board EMI/RFI input filter and ESD protection.
- On-board low noise voltage regulators for the driver op-amp and DC servo.
- Power and output terminal blocks accept wire sizes up to AWG 10 (5.2 mm2).
- All leaded. Easy to solder. 90 × 70 mm board footprint.
- Bill-of-materials includes a Mouser Electronics Project Link as well as Digikey part numbers.

"....My interest in electronics started well over 30 years ago. I’ve been employed in the field since 1991 and in 2002, I earned my Master’s degree in Electrical Engineering at University of Washington, Seattle. In my day job as a Senior Circuit Design Engineer at Texas Instruments, I design precision analog circuits for use in cellphone base stations....."
