I was much inspiredby his MC pre-pre. This makes me really sad, especially considering that i never met him. 70 is too young.

I've always admired him for his original work and profound depth of understanding that was the basis for his advancing audio electronics design. A true engineer in many senses of the phrase- he helped to set things straight in a field that perennially suffers from much hype and pseudo-science.

A sad day. If we progress by "standing on the shoulders of giants" I suppose there'll be one less giant to depend upon.

A sad day. I've built several of his project and used his amplifier design in my home system almost exclusively since the mid-70s. He taught thousands of students and gained many admirers.

Default A true Southern Gentleman

Marshall's passing is a tragic loss for everyone who knew him and for all of the audio enginerring and audiophile community. A true Southern Genttleman who was brilliant, generous and gifted in his ability to explain things to others. He will be sorely missed and his work and accomplishments will be long remembered.

Default A new viewpoint

It's sad to hear that Mr.Leach is no longer with us. I'm really grateful to him for the articles he wrote.
However , while he might not be able to give us more " electronic inputs " it might be interesting to know where he's gone .....!
Check out my thread at :

Please post opinions there on " that subject " . We'd like DIYAUDIO members to post their opinions for or against.

Just learned of this

His website was invaluable to me when I first started to pick up the interest in audio electronics. Today I am still a fan of the Triple Darlington output stage as used in the Leach Amp. I really hope Georgia Tech keeps his website in place as it is an invaluable resource.
