The Dizengoff Audio DA2 is a tribute to the venerable RCA BA2C tube preamp. RCA’s BA2C found wide use in film, broadcast, and recording during the 1950’s.
The DA2 has wonderful headroom, and it packs a nice low-mid wallop. The tone is smooth, warm, and sort of heavy–just what you’d expect from an American tube design of this era.
Signal transformers are wound in Chicago. The DA2 uses a hi-nickel input (80% nickel) and lo-nickel output (45% nickel) for excellent fidelity. The transformers are based on early Peerless designs, and their frequency response is flat from 10Hz to 50kHz.
The power supply is internal. Like the D4 and D864, it’s built around a Japanese Nippon Steel R-core power transformer. It has extremely high efficiency and low noise compared with traditional E-I core transformers and plays a significant part in achieving the DA2’s low noise performance.
Designed and built in the US, these units are solid, well constructed, and produce authentic tones you'd associate with much more pricey options.
