Default Quantum 102 Pre-Amplifier

I have a Quantum 102 Pre-Amplifier which mates with a 202 Power Amp. These date from the early eighties.
The pre-amp has 4 x LM301AN op-amps fitted. Would replacing these op-amps with either NE5534, OPA604AP or OPA134 improve the sound quality of the pre-amp? Would any other mods need to be carried out by replacing these op-amps such as fitting 100nF capacitors between power supply pins of the op-amps and ground.
Thanks in advance for any advice.
