CLS509的聲音細節會浮現很多 聲音飽滿 低音更清晰可見
Chang Lightspeed公司於1991年成立於美國的俄亥俄州，總裁Michael Chang有感當時所有市面上的電源濾波產品都無法達到他的標準，因此決定自己研發，設計出不使用延遲/噪音(lag/noise)感應變壓器或線圈，且 能減少AC電源污染的濾波器。
一般使用感應線圈來阻隔極高頻噪音的產品
會產生時間延遲(time-lag)
Chang Lightspeed使用"lossy transmission"
不會產生時間延遲又可解決RFI/EMI的干擾
Chang Lightspeed專業電源濾波器主要分為3個等級：level 1、Level 2及Level 3。電流通過Level 2濾波為Level 1濾波的2倍，電流通過Level 3濾波為Level 1濾波的3倍。最新發表的HyperDrive技術，又大大的提升其效果。
The CLS 715 uses the Limited edition as a design base and incorporates the newly developed filter core (core-L4) to boost the performance. As well, the CLS 715 uses HyperDriveTM technology. The HyperDriveTM technology reduces noise to levels far below any of its predecessors. Additionally, this newest innovation by Chang improves sound stage, dynamics contrast, inner details, 3-dimensionality, high frequency extension, and video reproduction. All in all, Chang’s HyperDriveTM technology stretches the performance of the Lightspeed Powerline Filter to an unprecedented level.

More about Lightspeed Powerline Filters:
Lightspeed Powerline filters effectively block performance decreasing AC contaminants from affecting other components.
Traditionally AC filtration employs the use of inductive coils to block ultra-high frequency (RFI and EMI) noise. Coils have a fundamental drawback when used to filter AC for an audio or audio/video system. They introduce an unavoidable time delay when subjected to instantaneous high current demands, common when power amplifiers attempt to reproduce high level musical transients. The sonic penalties of this time delay include smeared transients at all power levels and diminished crescendos that lack true speed and impact of live music. Video performance suffers from reduced shadow detail, particularly in fast moving scenes that rapidly vary from light to dark and back again.
Lightspeed technology provides both protection and enhancement. Each Lightspeed Powerline Filter passes the power transmission (AC) line through a unique multi segmented "lossy transmission" mechanism composed of select magnetic materials. This mechanism maintains proper impedances while severely reducing the effects of RFI/EMI. The total lack of inductive coils, including isolation transformers, ensures full current delivery and uncompromised performance.
