McCormack DNA-125/225 Upgrades

I think the upgrades provided by SMc Audio to my DNA-2 Deluxe are an incredible value.
There is more to it than just a parts and labor ratio. With the more extensive upgrades, you are essentially getting a new amplifier along with a new warranty. If you have a problem or question, the designer and technician are a phone call away. There are many factors besides the huge perfomance and sound quality benefits.

The stock DNA-2 Deluxe was a very good amp, powerful and musical. With the Gold revision and input transformers, it has exceeded my initial expectations and my appreciation for the quality continues to grow. There is no pondering the parts vs. labor ratio here.

There are a few new amps that have become available since I decided to have mine upgraded and most have magazine reviews that wax poetic how wonderful they are. It is not possible for most of us to audition all the choices, so our "research" is often based on the feedback from others.
To my knowledge, there are no magazine reviews of the McCormack revision amps, but a long list of feedback from satisfied customers. I consider this type of endorsement more credible than most magazine reviews.

Bruce's review is just what I was referring to about credible posts from satisfied customers. Very articulate and descriptive. A single good review like that is very helpful to anyone who is trying to find their way through the maze of audio gear. Good job Bruce!

Mitch, we all have to try to place a comparative value on our purchases. You do have a good point regarding the additional labor of disassembly. For that reason, plus the additional cost of double shipping, I urge people who send in for upgrades to have as much done as possible the first time they send in a component rather than plan to upgrade in stages. The Siltech carbon wire, which was not available at the time of my upgrade, is one good example how you will save money. Be sure to read about it and you will see what I mean.
