Know before you buy
While many switching amplifiers struggle with high-frequency noise, the No. 53 uses proprietary Interleaved Power Technology (IPT) to push switching frequencies to 2MHz. This effectively moves noise far beyond the range of human hearing, allowing for a ruler-flat frequency response without the harshness often associated with the category.
Yes, the No. 53 is designed to deliver 500 Watts into 8 ohms and is engineered to handle virtually any speaker load. Its robust power management ensures consistent performance even when driving demanding or low-impedance speakers.
No, the amplifier is designed to maintain a constant, thermally balanced operating temperature. Because of its efficient switching design, it generates significantly less heat than traditional linear amplifiers, even during intense listening sessions.
The No. 53 is a substantial piece of equipment, measuring 21 inches high by 9 inches wide and 21 inches deep. It weighs 135 pounds, so you will need a sturdy, dedicated equipment rack or platform that can safely support its weight and dimensions.
By operating at 2MHz, the amplifier can utilize much gentler output filters. This design choice prevents negative phase shifts or roll-offs in the audible audio band, resulting in a cleaner, more accurate sound reproduction across the entire frequency spectrum.
