I have been told by a respected Audio Research repair expert that infinicaps were used as opposed to oil based caps. or other choices partly because of size consideratiions. That being said, I have had Classic 150 monos upgraded to infinicaps by ARC. I am pleased with the results. It is not a radical difference, but the music sounds more dynamic. I still prefer this unit to newer models.
InfiniCaps in Audio Research gear
Who out there has tried InfiniCaps in older ARC designs or had ARC mod your unit with these caps . I am just wondering what others have felt about the results. I have an SP9, which was discontinued before InfiniCaps were used by ARC. I am very pleased myself with the results after swithching out several WonderCaps for the InfiniCaps. Anyone else try this. What did you think when you were done? What unit did you try it with?
My next step is to attempt to put an IEC connector on it and plug in a better power cord.
