最近、5Vリニア電源（LPS）の使用について多くの良いフィードバックをいただいております。ご存じの通り、店主は先週のFacebookの「CASフォーラム」で「共同購入 - リニア電源」を企画しました。その結果は驚くべきもので、新規のお客様の中には、高品質のリニア電源を使用することでRaspberry Pi 3の音質が本当に改善されたと話す方もいらっしゃいました。これは、Raspberry Pi 3内部のコンポーネントがオーディオ愛好家向けに作られたものではないためです。 疑いの余地なく…リニア電源（LPS）は低音をさらに強化し、微細なディテールを向上させ、高音をより滑らかにします。
そこで店主は、お客様の要望に合ったケーブルの設計を開始し、AfterDark Project ClayXは、この特別なRaspberry Pi 3用ケーブルの研究開発を開始しました。
AfterDarkの「サウンドチューニング」には主に2つのコンポーネントがあります。Raspberry Pi 3の交換用ケーブルの芯線の素材、カーボンファイバーシールド素材、そしてパワーコンディショナーの設計とフィルタリングキャパシタの選択です。より良いケーブル、電力供給により、各設計段階でPi 3の音質を大幅に改善することができます。

This week the shop owner will talk about the important of using LPS for Raspberry Pi 3
There is so many client asked shop owner, what is the different between AfterDark. daisyCAS and AfterDark. audiophileCAS DTD?
shop owner will reply: The major different is audiophileCAS DTD is using a high quality LPS instead of Switching Power Supply.
The other major different is using industrial MicroSD card instead of consumer grade MicroSD card.
Recently, we have a lot of good feedback on using 5V LPS, therefore, you may know that the shop owner was organized a "Group Buy" on this special 5V LPS. The result is so surprised, some new joiner using Raspberry Pi 3 indeed whatsapp the shop owner saying it really really improve a lot from bass, the authority of sound stage, better micro details, and much smooother in high-treble.
Therefore, due to demand on other client, the shop owner started to received special modification on this "Group Buy" Linear Power Supply. It includes request to change the power-Inlet to audiophile one, changing audiophile fuse, placing EMI label on the IC near the Telema transformer. Placeing AfterDark audiophileMAT under the LPS etc.
The client told the shop owner: this micro change can improve the weak point of the Linear Power Supply. Due to costing, most factory cannot affort to install this expensive component to LPS. So, please take this job and modify for this Linear Power Supply.
This was a busy week after "Group Buy" order. One day, the shop owner received another recently customer request to replace the 5V DC MicroUSB Cable with something special material.
The client ask: It is possible to change the power cable, not to use the MicroUSB connector, just put it directly to the GPIO ports inside the Raspberry Pi 3?
The shop owner reply: Yes, this can be done with some modification work. Please wait for my good news next month.
Therefore, we start to design the cable with customer requirement and initiated AfterDark. Project ClayX Research and Development for this special power cable.
There two major components for AfterDark sound tuning. The carefull selection of cable core wire material, the shielding material and the power conditioning parts for Raspberry Pi 3 on 5V and 3.3V. Every steps can improve dramatically with better implementation on power supply.
