Default 2nd stage amp.

hi I know its been done, as the best sounding opamp, but I have 2 specific q's please.

1/ best single op amp for a first stage 100 ohm load ( noise) amp with about 50db gain

currently using lt1028, but is there better sounding given coinstraints.

18 volt _/+ rails

I can check feedback R's if need be.

2/ following on we have passive riaa stage so loading requirements, I can check values if need be

and a dual opamp with a bit of make up gain, I think its bog std. 5532 here.

so how do I better the 5532 with
1/ a conventional dual and

2/ with an adaptor praps?

thanks for help

This is for a phono input stage right?

Douglas Self has written comprehensively on the subject and has a great website. If you can post some more info e.g. impedance of your cartridge & output level I'm sure there's a lot of knowledge on the forum.

You've searched on the subject here right?
