Parasound DAC-2000 Ultra - World Class R2R DAC [Expired]


no longer for sale

Rare opportunity to acquire this is outstanding DAC, which was made in USA, and is still considered one of the finest DACs available.   This is the 19" faceplate model (SN 605512631) in excellent condition.   One minor nick on the top of the faceplate as shown in the photo.    

Based on the Ultra Analog discrete ladder DAC chip - the legendary Ultra Analog D20400A.  This DAC module was used in the flagship products from Levinson, Classe, Spectral, Sonic Frontiers, Threshold, and Parasound. 

Ultra Analog desinged the D/AC 2000 Ultra for Parasound incorporating lessons learned from their involvement with prior flagship DACs.  I've owned the Classe DAC-1 and heard others.  Overall, this is my favorite UA based DAC.

The rest of the chipset includes a Pacific Microsonics digital filter the PMD100 to decode HDCD and the Ultra Analog AES21 custom input receiver.

4 digital inputs including: Toslink, Coax. ST Optical, and AES EBU.  Analog outputs are both balanced XRL and single ended RCA.
