McCormack LD-2 Preamplifier and DNA-250 Stereo Power Amplifier
In 1997, McCormack Audio was purchased by Conrad-Johnson, known primarily for their fine tube amps and preamps. A new line of McCormack amplifiers and preamplifiers has since been refined and updated. They have the same high quality and value that Steve McCormack put into his designs in California, but these current products are basically an entirely new line (and are built in Virginia). The LD-2 (line drive preamplifier) and DNA 250 (two-channel power amplifier) are designed with the audiophile in mind, but at a price that puts it into the reach of the masses. This review offered me some interesting challenges and some surprising rewards. Did I mention I broke down and got an iPhone? I will explain why I mention this at the end of my review.
