Hi ClieOS, I am curious about how the original E12 compares in terms of transparency and soundstage to the E12DIY when it is fitted with the same OPA1611 and LME49600 chips as the original E12. Does the more simplified circuitry of the E12DIY improve the transparency/soundstage if using the two same chips mentioned? Is the improvement substantial? Thanks!
My E12 is the very first batch with LME49710 instead of the later OPA1611, so I can't give you a direct comparison. But I am comfortable to say that given the audible difference between my E12 and E12DIY, I have no doubt the E12DIY will be better even with the same opamp+buffer setup, and OPA1611+LME49600 is not even the most transparent or widest soundstage of opamp+buffer you can use on E12DIY.
