Default lm1458 and lm358 upgrades

hi, i listen to alot of music on sat. and would like to upgrade these two opamps in my satellite receiver. i have some ad8620s on hand could they maybe be used as upgrades for these chips? also will the ad8620s, run fine on single, instead of dual voltages? i guess i might have to add some bypassing at power pins also. thanks crippledchicken

I've used a whole lot of LM358's in the past.. Good single supply opamp capable of driving high capacitive loads.

Linear Technologies LT1013 is a good upgrade.

hey thanks maylar, it seems like the positive 34v single supply is pushing it but, came like that stock. i'll check out the lt1013s i know i put the lt1122s in my adcom preamp, which sounded really good. thanks, crippledchicken
