Know before you buy
Yes, the Ares II is designed to handle both. It features three selectable gain settings—40dB, 55dB, and 64dB—to accommodate a wide range of cartridge output levels.
You can configure the loading and capacitance settings internally within the unit. This allows you to fine-tune the electrical environment to match the specific requirements of your cartridge for the most accurate sound.
The massive, fully regulated outboard power supply keeps the sensitive amplification circuitry isolated from electrical noise and interference. This separation is essential for maintaining the low noise floor required for high-performance tube amplification.
Yes, the unit includes a dedicated mono switch. This is particularly useful for older mono recordings, as it helps reduce surface noise and provides a more focused, stable image.
The timer-delayed start allows the tubes to reach a stable operating temperature before the signal path is fully engaged. This prevents unwanted turn-on noise or pops from reaching your speakers.
The Ares II includes built-in subsonic filtering to help manage low-frequency rumble and prevent excessive woofer excursion. It is designed to ensure optimal performance without interfering with the audible frequency range.
