- The BRZHIFI C245-TOP fully balanced preamplifier is crafted for the discerning audiophile, seamlessly integrating sophisticated circuit architecture with audiophile-grade components. Featuring a dual-transformer power supply and a fully balanced design, it ensures an ultra-low noise floor while delivering a transparent, nuanced soundstage. With support for both flexible tone adjustment and a pure, direct-path mode, it infuses high-end two-channel HiFi systems with exceptional resolution and musical dynamism.
- Independent Power Supply Architecture for Left and Right Channels
Equipped with two 30W audiophile-grade pure-copper E-core transformers—each housed in a dedicated shielded enclosure—this design ensures completely independent power delivery for the left and right channels. This effectively eliminates crosstalk, resulting in a wider dynamic range and an exceptionally low noise floor.
Fully Balanced Input and Output Design
Featuring a variety of fully balanced and single-ended interfaces (including high-quality XLR and RCA connectors), the system establishes a lossless, fully balanced transmission path from input to output, significantly enhancing interference rejection and signal integrity.
Audiophile-Grade Filter Capacitor Matrix
The main filtering system utilizes eight 4700µF electrolytic capacitors imported from the U.S., complemented by premium, classic audiophile-grade capacitors from brands such as Rubycon and ELNA, ensuring an abundant and pristine energy reserve.
Japanese ALPS27 Precision Potentiometer
Incorporates an authentic Japanese ALPS27 motorized potentiometer, offering smooth tactile feedback, excellent channel matching, long-term durability, and seamless support for remote control operation.
Tone Control / Direct Mode
Includes a high-precision tone control circuit (for treble, midrange, and bass adjustment) alongside a “Direct” mode, allowing for precise fine-tuning to suit different source material and individual listening preferences.
