Something wrong there. My DNA 0.5s always ran relatively cool, cooler than the 1.0s for sure. You will probably need to go to SMcAudio for service; while its in, spring for an upgrade. Really improves the amp.
amp pop - need help
just purchased a McCormack DNA-1 Deluxe. While the sound quality is greatly improved - better stereo separation, deeper bass, less harsh highs, improved dynamics - I have noticed the amp gets quite hot. After just a few hours the heat sinks are hot enough to be quite uncomfortable to the touch. Worse, though, the amp makes a popping noise as it heats up. Sounds a bit like metal expansion. . .the wife says it sounds like the last kernel of corn popping in the microwave.
Not sure if this is an issue but it sure is a big change over the previous amp that would run all day without overheating.
Any ideas?

Contact McCormack, they should know. The audiogon home page has a link to manufacturers but here it is, http://www.mccormackaudio.com/ [email protected] |
