FX-AUDIO DAC-SQ5J+ (Modified) Black. Nichicon MUSE. Nissei MMT Used. Many Other Additions
FX-AUDIO- DAC-SQ5J+ [Black] Equipped with Burr-Brown PCM1794A. High-Resolution DAC. This is a DAC equipped with Burr-Brown PCM1794A.
This is a modified version with capacitors and other components replaced and added.

Audio electrolytic capacitors Nichicon MUSE KZ and the highest grade Nichicon MUSE series.
As an FX-AUDIO feature, the board has empty spaces for users to add components at their own risk.
To enhance the low-frequency range, two Nichicon MUSE KZ capacitors were added, which may result in slight differences.

Some ceramic capacitors have been replaced. Two ceramic capacitors have been replaced with metallized polyester film capacitors, 0.27μF 50V Nissei MMT.
These are discontinued items. They are legendary film capacitors from the former Nissei Electric. The MMT type capacitor is an ultra-compact film capacitor that uses an extremely thin metallized polyester film and a laminated structure manufactured using NISSEI's unique method to meet miniaturization needs.

As originally intended, the 1-circuit to 2-circuit DIP can be mounted as usual. The sample OPA627AP is not included. It was mounted for confirmation.

After creation, the unit was powered on and tested for approximately 10 minutes. It operates sufficiently with a 12V 1A power supply.

Additional operational amplifiers included: Discontinued audio operational amplifiers. Discontinued National Semiconductor LME49710NA 1-circuit (two units) and one 2-circuit DIP. Discontinued National Semiconductor LME49720NA 2-circuit (two units) and two 8-pin DIPs. The additional operational amplifiers are new and unused.
A 1-circuit to 2-circuit DIP can be mounted in the front stage. Personally, I use the OPA637AP, although I am concerned about the heat generated. The range of operational amplifier usage is quite wide, so MUSE03 or 01 are also recommended.

Includes two CANARE L-4E6S 4-core (red) RCA cables, custom-made for directional sound.
Shielding is present when masking tape is applied.
A 12V 1A AC adapter has been added, so it is ready to use.
