The LME49860 can work at +/- 22V max

Thank you. Yes i hope hoping i could use the OPAs but is risky given the 22v, sure it will be better than the old 4560 o[amp

I would highly recommend you look at Burson Audio's Discrete op amp replacements. they are larger then an op-amp so you may have to look at space but they do offer some extenders to allow more flexible installation. I use a set in my MSB DAC and they are a huge improvement to my old out dated DAC.

I second the Burson Audio discrete op-amp. While I’ve not yet tried them, in principle I love the idea. Plan to get some V6 units for my NAD PP2 which I’ve already upgraded the power supply on from a wimpy AC adaptor to a LM7824 regulated supply with 4700uF pre-reg filtering and a Schottky rectifier diodes.
