Replacing the factory mains cables on your Meridian DSP5200SEs with Shunyata Research Theta NR cables is likely to result in a lower noise floor and improved transient response. Because your speakers are active, they house the entire DAC and amplification chain; cleaner power directly at the speaker stage often yields more perceptible benefits than it does for passive components.

🔊 Expected Sonic Effects
Based on the Theta NR technology and the architecture of the DSP5200SE, you can expect:

Increased Clarity & Resolution: The "NR" (Noise Reduction) technology provides >12dB of common-mode noise filtering. This allows low-level textural details in your Roon streams to emerge from a "blacker" background.

Improved Soundstage Focus: Users of similar high-end power cables on Meridian systems often report a wider and more coherent soundstage. The Theta NR is designed to reduce "hard transients," making the imaging feel more natural and in-focus.

Dynamic Effortlessness: The 10-gauge VTX-Ag conductors (silver core with a copper outer layer) are built to handle sudden dynamic shifts without the compression sometimes felt with standard thin-gauge factory leads.

Tonal Balance: The combination of silver's speed and copper's warmth aims to provide a lifelike presentation that complements the precise, sometimes lean, nature of Meridian’s Beryllium tweeters.

🛠️ Technical Considerations
Active Speaker Synergy: Unlike a traditional amplifier where power is only for the output stage, your DSP5200SEs use power for the DSP processor, DACs, and three 75W Class-AB amplifiers. Filtering noise at this "all-in-one" endpoint is highly efficient.

Digital Signal Integrity: Since you already use Audioquest Vodka (silver-plated) for your network chain, your digital signal is already highly optimized. The Shunyata cables will address the final "analogue" vulnerability: the power entering the speakers' internal electronics.

KPIP v2 Processing: These cables are pre-conditioned for 4 days, which significantly reduces the traditionally long "burn-in" time for high-end power cords, meaning you should hear the benefits almost immediately.
