Looks to be 3 OP amps per channel in parallel?
Half ad8397 per channel(4 in total). And half opa1602 is used to perform error correction. The other half of opa1602 is possibly to do the flying supply or something else. Perhaps it generates the differential signal and pair with a differential amplifier.

788: opa1602 + ad8397
789: opa1602 + opa564
887: opa1612 + opa564
888: opa1612 + opa564 + bootstrapped supply
788 - Monoprice Monolith DAC+Amp
789 - Drop x THX AAA amp
887 - Monoprice Monolith amp
888 - SMSL SP200, Benchmark HPA4

Am I missing any (besides the Benchmark ABH2 loudspeaker amplifier)?
