Doug, firstly thanks for your article. Indeed that is an inexpensive upgrade. However, I am confused. The eastern Electric Minimax DAC I recent purchased (and love) has a tubed output. The pictured DAC is also tubed. Have you bypassed the tubed output in favor of the opamps and their upgrades? If so, how does the upgraded opamp compare to the tubed output. Am I missing something here?
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.
