anybody tried Vishay/ROE MKP1839 capacitors in RIAA?
They are available from Mouser with 1% tolerance (part #:75-MKP1839310401).
I wonder how they perform vs Panasonic ECW's supplied with the kit ? Is it worthwhile replacement?
You could certainly get a bunch of the 0.01uF caps to make the values needed in the circuit. In terms of RIAA accuracy, you may get a few tenths of a dB closer to the ideal. They could also sound a bit different as well.
