Know before you buy
By isolating the left and right channels within the chassis, the design prevents crosstalk and interference between channels. This results in a more expansive soundstage and improved imaging accuracy.
These specific tubes are chosen for their exceptional linearity and low-noise characteristics. They provide a refined, transparent sound that maintains the warmth associated with triode designs while offering high-frequency clarity.
No, the relays are strategically placed to keep the signal path as short as possible. This minimizes the risk of signal degradation that can occur with traditional mechanical switches or long internal wiring.
The heavy-gauge aluminum chassis is designed to be highly rigid, which effectively dampens vibrations. This minimizes microphony, ensuring that external mechanical noise does not color the delicate audio signal.
Teflon capacitors are widely regarded for their superior dielectric properties and stability. They contribute to the preamplifier's ability to resolve fine detail and maintain tonal accuracy across the entire frequency range.
The remote manages both volume levels and input selection. It interfaces with the internal microprocessor to ensure that adjustments are made precisely without introducing noise into the audio signal path.
