The NHB-108 Model Two is darTZeel's ultra-fast, dual-mono, solid-state power amplifier in the NHB series. It uses two separate power supplies, transformers, audio circuits, and cooling systems to realize a true dual-mono topology while remaining a stereo power amp. It offers three analog input options: RCA, balanced XLR, and darTZeel's proprietary 50-ohm BNC Zeel interface, each with high input impedance for conventional line-level use except the Zeel current-mode input. Nominal output power is specified at 150 watts RMS per channel into 8 ohms and typically 225–250 watts RMS into 4 ohms, depending on the published spec set, with 26 dB power-stage gain into 8 ohms. The output stage is a very wide-bandwidth, class‑AB solid-state design with extremely low output impedance (≈0.33 ohms from 20 Hz to 20 kHz), yielding excellent speaker control and linearity. Its patented circuit architecture minimizes or eliminates global negative feedback, aiming to preserve signal integrity, timing, and microdynamics while maintaining low measured distortion. Frequency response is rated from about 0.8 Hz to 600 kHz (+0/–3 dB), with rise time under 0.8 µs and slew rate above 88 V/µs, reflecting the amplifier’s ultra-wide-bandwidth, high-speed behavior. The chassis features the brand’s distinctive gold anodized aluminum front panel, red heatsink fins, and a glass top cover, with overall dimensions around 440 × 170 × 350 mm (W × H × D) and net weight about 30 kg. Idle power consumption is roughly 50 W, rising to around 900 W at maximum output, so appropriate ventilation and mains provision are recommended. Designed as a reference-level amplifier, the NHB‑108 Model Two is positioned as a centerpiece for high-end systems, intended to drive a broad range of loudspeakers while emphasizing clarity, transient accuracy, and an unforced, highly resolving presentation.
