I have narrowed my search for the ultimate OpAmp for bass reproduction to: OPA-627,AD-843,AD-845,AD-825.I will be using a Jung/Galo regulated power supply for the preamp of a bass guitar amplifier I am modifying. The three stage OpAmp preamp(input non-inverting, tone control , output inverting, will feed a tube 12AX7 driver/phase splitter for the tube output section. I am really only conserned with the quality of the OpAmps bass as the bass speaker used (15") has a frequency response up to 2500hz, if that. Anyone who has been comparing these OpAmps in their headphone amps I would realy appreaciate your subjective opinions as to which one is the bass king .
