i've removed opamp-buffers (output), bridged output caps, and replaced opamp with ad8620. the improvements are significant and very noticeable. now i'd like to replace some electrolytic caps with higher quality ones (if this indeed is a worthwile mod). wondering if i could have some suggestions on what to use. i don't think this application demands blackgates or anything that extreme. i'm leaning towards standard panasonic caps, with a bit higher capacitence than stock.

i'd appreciate some suggestions on type of cap and suggested capactiences
also: when i removed the buffers i bridged pads 1-2-3 and 5-6-7. is this necessary? or should i simply have bridged 1-2 and 5-6? wondering what others have done here? i don't like using more solder than necessary
also: interesingly, i seem to have a newer version of the 0404. bg's pic doesn't completely correspond to my card. some caps on bg's card are not present on mine, and some things are in slightly different places. interesting
