NuPrime launches IDA-8 Integrated Amplifier with New Class A + D Hybrid Amplifier and Built-in DAC

The big news in this integrated amplifier lies in its touted hybrid design and nod to modern digital sources. NuPrime claims that by utilizing discrete components in the Ultra-Linear Class A Module (ULCAM) circuit, the signal can be fine tuned to reduce noise and provide maximum power. NuPrime goes on to say that the amp circuit improves on traditional class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 600kHz. NuPrime makes is a point to emphasize that the switching frequency is double that of most Class-D amps, which switch at 300kHz or lower, and is well beyond the compact disc’s 44.1kHz sampling rate. NuPrime’s SRC IC chip is said to provide FPGA processing for ultra-low jitter and distortion rates.

It’s not often that a company specifically points out the products’ isolation feet. NuPrime has put some patent pending focus on the isolation feet by adding some patent pending feet that the company claims absorbs and cancels vibrations that degrade audio performance. In other words, there’s no need to add after-market sorbothane feet or other dampening products to the new IDA-8.

NuPrime further credits the IDA-8’s low noise floor to an innovative volume control based on a thin-film resistor design that positions a single resistor in the signal path for each volume setting. Volume changes occur in 99 precise 0.5dB increments for each input’s individually adjustable volume level. Precise level matching is a breeze, as is the user’s ability to make comparisons of music sources.
