LM4562 replacing an OPA 2134

I hope this isn't a stupid question but I noticed that the pin out for the LM4562 is identical to the OPA2134. I have a phono preamp based on the OPA2134 and wondered if the LM4562 could be used as a one for one replacement for the OPA2134.

I like the phono preamp (an Acoustech PH-1P) but couldn't help wondering if the LM4562 would make an improvement. There is sufficient buz about the LM4562 to at least check the possibility out.

There are four OPA2134s in the preamp. All of them are 8 pin DIPs mounted in sockets. I would like to try simply swapping the OP amps to see what I get.

Assuming this is possible, other than sound quality improvements should I expect any improvement in S/N performance?
