Know before you buy
The dual mono design means each channel has its own independent power supply and circuitry. This prevents crosstalk between channels, resulting in better stereo separation, improved clarity, and more stable power delivery even when driving demanding speakers.
No, the 14B³ is convection cooled, meaning it relies on its robust aluminum chassis to dissipate heat. This ensures completely silent operation, which is ideal for critical listening environments where fan noise would be a distraction.
Yes, the amplifier features switchable gain settings of 23dB or 29dB. This allows you to optimize the signal-to-noise ratio and volume control range based on the output level of your specific preamp or surround processor.
The amplifier is highly versatile, offering balanced inputs via XLR and TRS connectors, as well as standard single-ended RCA inputs. This ensures compatibility with a wide range of high-end audio components.
With 600 watts into 8 ohms and 900 watts into 4 ohms, this amplifier provides significant headroom and a high damping factor of over 500. This combination gives it the control necessary to manage complex speaker loads without losing transparency or musical detail.
Every unit undergoes a rigorous 100-hour factory burn-in process before shipping. You will also receive an individual specification sheet detailing the exact performance measurements of your specific amplifier.
