RWA六年前已被我blacklist，永不再買。

原來erji有條feed討論，我send去mod之前都冇睇過，其實我唔明強國巴打up乜，意思係咪又spin緊換少少嘢收咁貴好過去搶？

吓？RWA一向都有寫改咩㗎wor，大陸仔發現新大陸？

RWAK380AMP Modification Details
- Add 25x additional (super-low ESR) capacitance to headphone outputs stages’ +/- voltage rails.  We hard wire it to the PCB via short, high-purity Cardas Golden Section Litz copper wiring.  This enhances the headphone output stages to provide high peak output current when needed.

NOTE: 25x added capacitance is NOT a typo – there is only a small amount of capacitance on the voltage rails of the headphone output stages, and we use energy-dense, super-low ESR capacitance to strengthen the voltage rails considerably.

- Add 25x additional capacitance (super-low ESR) in parallel with the battery via short, high-purity Cardas Golden Section Litz copper wiring.  This enhances the internal battery pack’s ability to provide high peak output current when needed.

- Hard wire from the 4-pin BAL input pins directly to volume control IC via short, high-purity Cardas Golden Section Litz copper wiring (bypassing ribbon cable and connectors)

- Hard wire from amplifier output stage directly to 2.5mm TRRS BAL headphone output via short, high-purity Cardas Golden Section Litz copper wiring (bypassing ribbon cable and connectors)

tl;dr 咁人哋真係講到明係換幾粒電容同加幾條電線之嘛

d插頭呀線呀嘅製造價錢你估又好貴?
