PERFORMANCE LINE DIGITAL

Masterbuilt Audio Cables - performance line available at NORTHSTAR AUDIO

Although the digital binary bit stream is robust, there are many ways that this signal can be corrupted by low quality cables. Our digital cables are design to have an optimized impedance as per the type of cables: SPDIF ~ 75ohm; USB ~ 90ohm; AES/EBU ~ 110ohm. Furthermore, the connector and cable design are optimized to achieve the least amount of losses (ie. insertion loss and return loss) for the digital signal transfer between the transport/server and DAC.

The benefit of our cable design, high grade conductors, and materials translate to a digital cable with low jitter and attenuation loss. Performance Line Digital Cables benefit from the same proprietary elements of the rest of this line and provide the highest value performance possible in its class.

PERFORMANCE LINE SPEAKER CABLES

Masterbuilt Audio Cables - performance line available at NORTHSTAR AUDIO

Speaker cables are the final leg of that signal path and any degradation in signal nullifies the quality of components both before and after it.

Reactances such as capacitance, inductance, and resistance will modify the signal being transferred from the amplifier to the speaker. In fact, the crossover circuits inside your speakers use capacitors, inductor coils, and resistors to divide the frequencies. The combination of resistance, capacitance, and inductance is a potential source of coloration which can be seen as a distortion of the original signal.

MasterBuilt Performance Line Speaker Cables sound neutral because they have the least reactance due to their U.S. laboratory grade pure copper wire, the highest quality insulation available and proprietary design technology. Put simply, this is the highest value speaker wire on the market.

Features such as laboratory-grade 6N (99.9999%) pure copper manufactured in the U.S. for mission-critical applications, proprietary winding geometry to reduce interference, along with extremely precise-fitting connectors made from exotic materials, the Reference II Line of audio cables was designed for the finest quality of stereo components. If you desire sound quality of the highest caliber, you owe it to yourself to invest in the MasterBuilt Reference II Line.

REFERENCE II POWER CABLE

Masterbuilt Audio Cables - Reference Line available at NORTHSTAR AUDIO

The Reference II Line power cords can elevate your system to a performance level you might not previously think possible. This is due to the inherent ability of Reference II Line power cords to filter out EMI and RFI to an amazing degree. This drastically lowers the noise level of your system while also ‘super charging’ your components with enormous levels of dynamic range combined with ultra-high resolution of fine detail.

The Reference II power cord has a large gauge wire utilizing high purity U.S. laboratory grade copper with state-of-the-art insulation and greater complex winding geometry to significantly reduce both magnetic and RFI signals. Lastly, this cable is terminated with pure copper Rhodium platted conductors with ceramic particle damping to eliminate vibration resonance. For this reason, Reference II Line power cord will dramatically improve your sound quality, no matter what brand and model of power cord you’re presently using.

REFERENCE II INTERCONNECT

Masterbuilt Audio Cables - Reference Line available at NORTHSTAR AUDIO

Audiophiles understand that musical signals are delicate due to the very low voltages from the source and thus can be damaged by “average” quality interconnects which are not optimized for critical applications. These weak electrical signals must be transferred from source to amplifier, and any distortion in the form of reactance or low quality materials will distort or color the signal.

To prevent reactive distortion to the music, the handcrafted and built to order Reference II series utilize advanced engineering concepts and materials which are not available to the average audio cable company. A brief comparison to the world’s most expensive competitors’ interconnects will prove this to you.

Ultra Line

After eight years of research, MasterBuilt Audio is proud to announce the availability of Ultra Line cables. Ultra is based on exotic formulation and assembly techniques developed for information transmission systems by aerospace engineers.  MasterBuilt Audio is the only company licensed to utilize this technology for commercial audio use. Key to the audio version of the Ultra design is maintaining extremely subtle details by managing the flow of electrons through the conductors and the avoidance of interaction in both the conductors and insulating materials. Highly specialized winding techniques also contribute to Ultra’s performance advantages.

The benefit becomes evident with the first listening session. You hear low level detail you didn’t know you were missing. At the same time, you hear the fine detail of authentic timbres, harmonic richness, and a physical palpability that you’ve not experienced.

ULTRA INTERCONNECT

Masterbuilt Ultra Line Audio Cables available at NORTHSTAR AUDIOThe MasterBuilt Ultra Line Interconnect is the only type of its kind in the world, regardless of price. Based on a proprietary formula of non-metallic ingredients combined with an alloy of precious metals, Ultra was designed to simulate a “zero” resistance wire, as used in high profile organizations, both government and private. As Ultra Line wire is extremely expensive to manufacture using proprietary methods only available in the U.S. and as such, its price is by necessity very high and can therefore only be used in very select systems.

However, if you own an ultimate stereo system and music is a very important part of your lifestyle, Ultra interconnects are for you. Ultra Line Interconnects provide extremely wide bandwidth and a dynamic range which approaches true realism, with an amazing level of purity, clarity, and holographic depth. Each interconnect is handcrafted and is built to order. For the world’s finest systems, MasterBuilt Ultra Line Interconnects are the only choice.
