Mccormack DNA125 or Belles 150A Hot Rod

Steve,

Why does Mccormack still use the EI transformers instead of Toroidal transformers? Are the EI transformers sonically better? Just wondering.

Hello there:

I have the fortune of owning a McCormack DNA-225 Stereo Power Amplifier, very happy with it during several years.

Then I sent it to Mr. Steve McCormack to be upgraded to their top "Platinum Edition" and what can I tell you my friends ? the improvement is so huge that I can't beleive is my same Amplifier.

I did the same Top Platinum Edition Level Upgrading to my McCormack RLD-1 Pre Amplifier and I couldn't be happier I did it. I plan to keep that winner combo during many years to come, except I get a second DNA-225, upgrade it to "Platinum" and go Mono-blocks.

Great components, magnificent sound. Best, Antonio Machado.

Well, I've said this before, and I don't mind saying it again... The use of toroid power transformers does not *guarantee* anything beyond a certain type of radiated field geometry and a relatively high price. Properly designed E-I core transformers are perfectly capable of exceptional performance and offer superior value. Don’t get me wrong - I do like toroids and I sometimes find their characteristics quite useful, but as a group, they do not deserve their over-inflated reputation. I design products for high performance and *value,* and E-I transformers are essential for this goal. I spec power toroids for those relatively rare times (at least for me) when cost is not an issue, and then I source them from Plitron, who make the best toroids I have found. And I pay…a LOT!

Best regards and a Happy July 4th!

EXACTLY my experience, too!

And well worth the dough in the right application. Not to mention the carbon wiring as another aspect of the upgrade I received!!!!!

Well Steve I'm glad you shared that comment one more time because it is the first time I saw it.Thanks for asking Mfb33. Steve if you happen to get on this thread again, any idea when the line stage will be in production?
