Know before you buy
Class A operation ensures that the transistors are always conducting, which eliminates switching distortion and provides a highly linear, smooth, and detailed sound profile. It is widely considered the gold standard for sonic purity in high-end audio.
Yes, the A-300 is engineered for exceptional stability and can handle loads as low as 1 ohm. With its 20-parallel push-pull MOS-FET output stage, it maintains constant-voltage drive to ensure your speakers perform at their best regardless of impedance dips.
Yes, the A-300 supports both bi-amp and bridged modes. This flexibility allows you to tailor your setup to your specific speaker requirements, whether you want to increase power output or improve speaker control through bi-amplification.
With a damping factor of 1,000, the A-300 exerts superior control over the movement of your speaker drivers. This results in tighter, more accurate bass response and reduced coloration, ensuring the amplifier has total authority over the speaker's voice coil.
The A-300 is a monophonic power amplifier, meaning it handles one channel of audio. To achieve a stereo setup, you will need to purchase two units.
The 4-step gain control allows you to match the amplifier's sensitivity to your preamplifier and speakers. This helps minimize the noise floor and ensures you have a usable range on your volume control, preventing the system from becoming too loud too quickly.
