The only difference between the AD8620A vs AD8620B is the voltage drift per changing temperature ( 0.8 to 3.5 uV/C vs 0.5 to 1.5 uV/C) If that's critical then it is worth the price. Temperature range from -40C to +125C
Best sounding op-amp
I have a stock Music-Hall CD-25 that I'm planning on doing some 'easy' tweaks on. One of tweaks I had in mind was changing the op-amps. It currently has a pair of Burr-Brown OPA2134PA's, but I was curious if anyone had any experience/suggestions on other op-amps that might produce a little 'warmer' sound. Possibly considering one of the Analog Devices op-amps like the AD823 or AD827. Any feedback or recommendations would be appreciated.
thanks.
thanks.
