Here are some links to new JRC product the MUSES01, 02, 8820 and 8920 op amps as well as the MUSES72320 dual volume control.
MUSES01 JFET Input Dual Op Amp http://semicon.njr.co.jp/eng/PDF/MUSES01_E.pdf
MUSES02 Bipolar Input Dual Op Amp http://semicon.njr.co.jp/eng/PDF/MUSES02_E.pdf
MUSES8820 Bipolar Input Dual Op Amp http://semicon.njr.co.jp/eng/PDF/MUSES8820_E.pdf
MUSES8920 JFET Input Dual Op Amp 8920 http://semicon.njr.co.jp/eng/PDF/MUSES8920_E.pdf
MUSES72320 Dual Volume Control http://semicon.njr.co.jp/eng/PDF/MUSES72320_E.pdf
The MUSES72320 dual volume control with 0.25 dB steps looks very promising.
Mouser will be stocking this part. The Qty 1 price is $17.65.
Digi-Key's $50/unit price for the '01 doesn't seem real.
