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

Mechans,

If SOTA means chips like the ESS Technology 9018, I believe the DAC chip alone is over $50 if you buy in quantity. For instance: The ESS Technology ( I believe the number is 9003 Dac chip) is about $5 in comparison.

We tried to bring the best and many pro audio components use the op-amps we chose in the DAC as it is very reliable and sounds great.I've had other customers use other op-amps in the MiniMax DAC and a couple reported feedback that we chose wisely, as other op-amps they tried might have improved in one area but degraded sound quality in other areas.
I believe Chris from Clarity Cables had great success and recommended to Doug to try the op-amps that Doug used with similar great sonic results across the board.
I haven't tried the op-amps yet but will order some shortly for sure because I trust Doug's ears.
