Success Rolling Opamps in EE Minimax DAC


I'll try to reign in my nearly unbridled enthusiasm for a recent uber-economical tweak, rolling Opamps in the Eastern Electric Minimax DAC.

On encouragement of Chris and Melissa Owens from Clarity Cable I swapped them out (note; this voids the warranty!), with resounding success. A more powerful upgrade per dollar in decades of messing with systems and tweaks does not come to mind.

My brief instructional discussion on this experience appears at Dagogo.com

Anyone care to comment on the influence of the power supply on performance. There are competing DAC designs claiming the importance of power supply chokes or elaborate regulation and transformers to serve as important elements.

I suppose this is the sum of all the parts concession I can make but wonder too why the smaller parts are not given more respect or attention.

Kudos to Doug for shifting the direction.
