This was one of the most over engineered DAC when it appeared several years ago. It would have rivaled the best and most expensive DAC from their fellow British counterpart – dCS. The Zia Fulcrum is a tube output DAC with a 24 Bit/ 192 KHz sampling. It utilizes two 6922/ECC88/6DJ8 tubes (currently has two Sovtek 6922 tubes in it), one for each channel, and some very sophisticated digital to analog conversion technology prior to its finished analog output. You can google for the extensive write up on it where its advance technology basically place it as a computer managed DAC. Many have argued that this “revised” version is a much better sounding unit over Tube Technology’s Fulcrum DAC. Music was smoothly laid out with a tight bass and just loads of details. The tubes did a fine job of keeping it warm and very analog sounding without any digital glare. Digital inputs are 1x optical, 3x BNC (with one BNC/RCA jack included) and 1x AES/EBU. Digital out is 1x optical and 2x clock outputs. Analog out is via a pair of RCAs and a pair of XLRs.
Cosmetically, the unit is in very nice shape. Minor scuff marks from use but nothing major. We don’t have the original box but will securely pack it for safe shipping.
