Hi and thanks for reading this post.
Do you think it would be a good idea to replace the usual aluminium electrolytic capacitors on an amp board for the better specs of a solid state (polymer) type capacitor.
I have 4 aluminium electrolytic's around the dac chip (47uf 35v) and 4x 10uf 63v output coupling caps in the analog section, so 8 caps to replace in all, do you think a like for like replacement of the stock aluminium electrolytics for solid state polymer type caps would be okay in this situation.
I have done a google search and people have performed this on pc motherboards but there is not much on amps.
Many thanks in advance. John.

solid polymer electrolyte caps excell at low esr, esl - where those properties are important they can be technical "improvements"
last I looked they were only made for lower WVdc, no bi-polar versions
if you read Bateman's articles the latter properties point to their being poor choices for "signal path" coupling/DC blocking - if you believe nonlinear distortion has anything to do with "audio quality" in capacitors

Oh, right. This is an existing unit. The PP caps would probably be larger than the size of a D-cell battery, for 47 uF. Never mind.
