You already have OPA1612AIDRGR installed which is way better than any of the after market discrete opamps unless you are trying to go backward. This OPA1612AIDRGR is used mainly in "Professional Audio Equipments" and I am sure these are well matched opamps for this particular product. Most of the discrete opamps available in the market are just scam and dont fall in trap. I am in India and this proposal is not meant for anything I am interested in replacing your opamps, but I just wanted to convey the message. Thank you
