New, Unopened MUSES02D HiFi Op-amp, 2 pieces + 2 gold-plated sockets

We have developed the MUSES series of operational amplifiers, which bring together audio IC technology, focusing on sound quality, such as "enhancing the texture of sound" and "improving the reproducibility of space," through circuit technology, chip layout, and frame materials.
The MUSES series is an operational amplifier developed by pursuing sound quality without being constrained by materials, chip size, and productivity, which were barriers to improving sound quality in the past.

The high-quality audio operational amplifier MUSES02, which pursues "true sound" that resonates with the heart, is the perfect product for high-end audio equipment due to features such as:
- High-purity oxygen-free copper is used for the lead frame, which greatly affects sound quality.
- Thorough reduction of crosstalk between left and right (L/R) channels.
- Pursuing high-quality sound that resonates with the heart, which cannot be expressed numerically.

Nisshinbo Micro Devices previously developed the J-FET input high-quality audio operational amplifier MUSES01, which brought together audio IC technology, but the MUSES02 is a bipolar input high-quality audio operational amplifier developed to flexibly meet market demands.

Purchased from Akizuki Electronics online store.

I bought these for a DAC, but I didn't use them, so I'm offering them for sale.
As a bonus, I'll include two gold-plated sockets.

Thank you for your consideration.
