When I needed to replace aged electro-chemical constucted coupling-duty capacitors in a circut with limited PCB space, I used bi-polar (or non-polarized) electrolytics as a sonic improvement. Supposedly polarized caps distort half the time from odd-order harmonics due to passing signal via a charge-discharge cycle. But bi-polar electrolytics distort all the time, only now with even-order harmonics which are easier on the ears & harder to detect. Modern fabrication technology permits bi-polar construction in the same physical size package previously occupied by polar construction. In the USA, my local Radio Shack had Nichicon brand in the 4.7uf & 10uf values I needed.
