Meet the Dizengoff Audio DA2.  It’s a tribute to the venerable RCA BA2C tube preamp.  RCA’s BA2C found wide use in film, broadcast, and recording during the 1950’s.  I like to think of it as the “little brother” to the RCA OP6 because they use the same tube.

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 right here in Chicago.  The DA2 uses an amorphous Metglas input and large 5/8ths inch stack lo-nickel (45% nickel) output transformer for excellent fidelity and sizable low end.  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 Nippo 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.

With the unusual inspiration of the RCA BA-2C behind it, the Dizengoff DA2 possesses a sonic character that I haven’t heard in any other tube-based mic preamp that I’ve tried. Adding its low noise floor, high headroom and wide frequency response to the tube and transformer-based distortion of which it is capable has resulted in a characterful mic preamp, and one that delivers an overall performance that makes its price point attractive to those looking to expand their available sonic options.” SoundOnSound, January 2018
