MCCORMACK POWER DRIVE DNA-HT1 三聲道擴音機 (二手)

This is the very first McCormack DNA-1 to come into our shop. It's quite a nice piece with very impressive design and engineering. Hailing from the mid 1990's. 150W per channel makes it a very capable performer, able to drive most speakers with authority and grace. Cosmetic condition is close to perfect with no significant signs of wear. We performed a light service where it was re-biased and thoroughly tested in our lab. In our long term listening test it performed flawlessly and we can see why these have such a loyal following. Best of all it comes in its original box, but we'll also provide extra packing as needed for safe transit.The original manual completes the set.
