I find LME49720/49710 plasticky and artificial to death. Some people do not, and you might be one of those. In case you end up not liking it, you should also order LT1364CN8 and LT1028ACN8 (this one is mono, so you will need a
2x1 adapter) samples from Linear Tech and TLE2082ACP samples from Texas Instruments, so you have options and you can fall back to 2082 if you end up not liking any of them.
HA3-2525-5 can be had as samples from Intersil, also requires a 2x1 adapter like LT1028. No soldering required for any of these.
The best opamps these days come in SOIC form, which is smaller than the DIP8 opamps I am recommending to you and need to be soldered to
soic-to-dip adapters in order for them to fit in dip sockets.
If you can somehow acquire these on adapters, I highly recommend them: ADA4627-1 (there's the neutral B grade and the warmer A grade, both fantastic), OPA827, OPA1611, AD8597, EL2228 (this one is a dual, unlike the others in this list), and ADA4841-1.
