Know before you buy
While many tube amplifiers emphasize a lush, midrange-heavy sound, the Red October SE is tuned for source accuracy and spatial precision. It prioritizes clarity and detail retrieval, offering a more transparent window into your music rather than a colored or overly romanticized presentation.
Yes. Thanks to the Gen 5 power supply and advanced filament regulation, the amplifier achieves a very low noise floor of 360µV. This makes it exceptionally quiet, even when paired with highly sensitive headphones.
The five selectable transformer taps allow you to precisely match the amplifier to the specific impedance of your headphones. This ensures optimal power delivery, better control over the drivers, and a more consistent frequency response across different headphone models.
By utilizing a true dual-mono architecture within a single chassis, the amplifier prevents crosstalk between the left and right channels. This results in superior channel separation, which significantly enhances the width and depth of the soundstage.
The Red October SE is built using point-to-point wiring and turret board construction, completely avoiding integrated circuits or silicon chips. This classic approach makes the unit highly reliable and easier to service over the long term, as it relies on high-quality discrete components.
This is a substantial piece of equipment, weighing 68 pounds and housed in a heavy-duty 10-gauge steel chassis. You will need a sturdy, dedicated surface that can support its weight and provide adequate ventilation for the tubes.
