Thank you for looking.

The original DAC board has been removed and replaced with a Burr-Brown multi-bit DAC, the PCM1702. The sound of classic multi-bit machines is revived for the modern era. I believe it has a powerful and energetic sound.

Signal processing involves extracting I2S from the N-50's system board and upsampling to 192kHz with a sample rate converter (SRC4192I).
No unnecessary processing from digital filters, which can be detrimental to playback, has been applied. I believe it produces a straight and smooth sound without extraneous noise.

The sound is completely different from modern 1-bit (ΔΣ) DACs from ESS, AK, etc. While specs are important, DACs from an era when music was pursued more earnestly will surely reveal their quality upon listening.

BB's PCM1702 is well-suited for Western music and pop, and its successor, the PCM1704, is said to be the best multi-bit DAC ever made.

Notes
* Please purchase with the understanding that this is a personal modification.
* We will handle repairs for cases where the unit completely fails to power on upon arrival. Documentation will be included.
* Since the vTuner service has ended, internet radio cannot be listened to with the unit alone. You can listen via AirPlay from your smartphone.
* The smartphone app is no longer provided, so operation is limited to the unit's buttons and the remote control.

No claims/no returns.
