Does that make the 5534/2 a good candidate for the ClassA biasing modification?

Or does that indicate we should be taking the output from PIN5?

I would change out the 25/25 electrolytic caps in the HF section first. I don't know if you can fit a film cap in there. C11/111 doesn't need to be 25uf. Try one side first to see if you can hear a difference.

Use OPA2132 or SMD to DIP adapters and OPA827.

Personally, I would not use the 2134 or it's quad version. The 827's are twice the price of even the 0132 series chips, but they are superlative. To me, the 0132 series and 827 are upgrades that the trained ear can hear readily. Very low distortion; quite transparent. With such low distortion IC's, excellent and very sharp imaging are possible with stereo program when near field or a minimal reverberant field is possible.
