I would suggest that although they are a better choice they are still not optimal. I never use electrolytic caps in the signal path. Lots of equipment use elcos in their output or input stage for this purpose. I always replace with film. In some of my better equipment I use Mundorf Supreme. Ampohm were exceptional vfm before they went out of business (although I believe they are being produced again now). Lots of the better philips players used nichicon bi-polar elcos and Marantz used elna silmic for this job and can again be improved upon by using film caps. I spent some time looking at DC servo circuits to null the DC offset on an output. This would mean you don't need any cap at all, I also used an adjustable constant current source tied to the output of a dac to trim dc offset to nil and remove the caps. What John is suggesting looks interesting. As suggested it would potentially mean you didn't need to open the sb. One question I do have, is would a biased cap actually sound any better than an elco bp. I already suggested that I use film or no cap where possible and I wonder where in the performance table a biased STD elco might fit? -- UV101 Touch,Linear Low Noise PSU,2 Regs,2 direct Clocks,Caps..
