“It looks like it was designed to sit on a smart person’s desk, beckoning constantly to be used. With every headphone I tried, it performed as though it had been engineered to present recordings in the most vivid manner possible, be 100% musically satisfying, and be the last headphone amplifier any of us might need to own. “

“It’s always fun reviewing high end gear. The Feliks Audio Envy 300B tube amplifier is among the best on the market. It’s a truly high-end amplifier with an incredible sound. It costs a pretty penny but if you have the budget you will never ever need a different tube headphone amp.
The Feliks Audio Envy is a future classic already. If you have the chance listen to it, you absolutely should. And sorry about your wallet, because you’ll want one once you’ve heard what it is capable off.”

Product Description
Furutech NCF Clear Line – Passive AC Power Optimizer
The Furutech NCF Clear Line is a high-performance, audio-grade passive AC optimizer designed to enhance the quality of your system’s power supply — effortlessly. Simply plug it into any unused outlet on your wall receptacle or power conditioner and let it go to work.
Installation takes seconds. The improvement is immediate.
There’s no need for prolonged comparisons or repeated A/B switching to convince yourself something has changed. The difference is apparent right away — a deeper, more focused soundstage, improved harmonic structure, and better overall tonal balance.
With the NCF Clear Line in place, you can expect:
- Greater soundstage depth and image focus
- More natural harmonics and smoother tonal balance
- Cleaner, tighter low frequencies
- Lower perceived noise floor for improved definition
Remove it, and the system’s presentation immediately feels less refined and less dimensional — a clear indication of how effectively it supports your system’s performance.
While it delivers impressive results in two-channel audio systems, the Furutech NCF Clear Line can also enhance home theater and video setups, helping reduce noise and improve overall clarity across your electronics.
If you’re looking for a simple, non-intrusive upgrade that can elevate your system’s performance in seconds, the Furutech NCF Clear Line is an easy addition with immediately rewarding results.

- Improves resolution, focus, and 3-dimensionality of performance.
- Eliminates noise increasing signal to noise ratio boosting information and detail in sound reproduction.
- Improves resolution, depth, and dynamism of images and videos.
- Multi-material hybrid construction: Carbon fiber housing (shell) with superior resonance damping properties.
- All conductor parts are rhodium plated and treated with Furutech’s Two-Stage Cryogenic and Demagnetization Alpha Process, which significantly improves every facet of audio and video performance.
- NCF Body (multi-material hybrid structure): NCF formulated nylon resin.
- Coils: ? (Alpha) Pure-Copper Rhodium-plated Conductor electrodes and passive “Air Coils” constructed with ?(Alpha)-OCC, enameled wire coated with a silver color resonance damping material.
- Housing: 4-layer hybrid NCF carbon housing composed of an outer hard clear coat over an NCF textured carbon fiber particle composite layer with another layer of NCF and 3K carbon fiber layer beneath that. The inner surface is NCF Nylon insulation, which is one of the best damping and insulation materials to improve frequency extension and tonal balance.
- The internal air chamber is pressure sealed for additional damping effects.
- NCF End Cover (multi-material hybrid structure): Anti-static and resonance suppressing qualities with molded channels to increase the surface area of the NCF material by 76% for improved effectiveness – ultimate resonance damping for improved tonal balance.

“I heard it primarily as more specific soundstaging especially with front-to-back sorting. There was greater organizational clarity for the overall structure of imaging. When focusing on what made it so, I saw higher microdynamic contrast. With it the difference between space made audible by very low-level recorded reflections aka reverb and the sounds themselves arising in said space was more marked. It’s casually referred to as higher image pop.”
“Simultaneously the empty space was more alive with subliminal data.”
“the Furutechs resolved more shadowy movements in space to make its presence more tacit.”
“you won’t be able to remain a tweak cynic when you hear this!”
