I am considering trying the Burr Brown OPA 627 in the I /V slots with these handy guys ( http://www.audiophileproducts.com/opamps see OPA 627 Superchip), essentially 2 SOICS premounted on a DIP-8 adaptor. I've figured these seem like the right opamp from me because their darker, rich sound would balance out my bright Grado 325is, which with the stock opamps i find too bright and fatiguing. I've countlessly read up on many of the other opamps, but their characteristics don't seem to line up with what i'm looking for which is a visceral, natural and warm sound as opposed to distant, bright, larger soundstage etc.
My question is, has anyone tried the 627s in the Xonar essence STX? If so, observations? I understand the 637 would be a bad choice because of the higher gain it requires, but from what I can tell the 627 should work just fine.
Second, is there any significant benefit to using the line-out for my grados and playing around with the buffer op-amp? I realize that I could endlessly toy around with different combinations in the buffer and the I/V but I honestly don't have the time. My big goal here is simply to move away from the bright fatiguing sound to something warm and punchy, without losing too much detail of course and it seems to me that the 627 is the best choice given its reputation and description.
If that's your goal you won't regret moving to discretes. No IC op-amps are as warm in my opinion.
