Product Description


From the Manufacturer

Ultra- High Performance Fiber Optic Cable Greatly Reduces Jitter and Maintains Optimum Signal Integrity for Smoother, More Detailed Sound from CD Players, MiniDisc, DVD Players, DACs, and Satellite Receivers.

If You Demand Audiophile Quality Sound, Using Audiophile Digital Cable is Essential

Many fiber optic cables use generic fiber. This limits the amount of light that passes through the cable, causing signal loss and jitter.

These cables are typically terminated by machine, which leaves the optical fiber rough. As the signal is transferred, portions of the light reflect back and forth within the cable. This causes jitter, a phenomenon unique to the digital domain.

Jitter is a non linear distortion, a temporary fluctuation of the digital audio signal that it reduces dynamic range and clarity, while compressing the soundstage and significantly raising the noise floor. Your CDs and movie titles will sound good - not great.

Interlink LightSpeed™ Reference Features Higher Quality Optical Fiber for Superior Digital Sound

ILSR features a high quality special index optical fiber that allows the maximum amount of light (signal) to pass through the cable. This far superior bit stream transfer maximizes bandwidth and delivers the crystal clear, incredibly lifelike digital sound that DVD, Dolby Digital, and DTS are renowned for, with total accuracy.

Precision polishing of the fiber helps reduce cable-induced jitter and substantially lowers the noise floor. The digital signal can travel smoothly down the light pipe, unimpeded.

You'll hear increased dynamic range, a more three-dimensional soundstage, pinpoint imaging and superb clarity.

Other standout features include Monster's unique spring-loaded pressure connection which keeps the optical fiber perfectly aligned between the output source and your component's input.

The Digital Cable That's in a Class by Itself

Your music and home theatre components are reference quality. They need a digital cable that's reference quality, too. Use Interlink Lightspeed Reference and get all the digital sound you paid for.

The good:

1) Very good build, fit, finish & choice of colors.
2) Spring loaded connectors are an advantage to eliminate stress while connecting & reconnecting to / from devices.
3) Looks great due to quality materials used. It was expected, after all this is Monster's Reference Toshiba Link (Toslink) cable, a.k.a. Fiber Optical Digital Audio Cable.
4) The Monster ILSR Toslink cable sounds very neutral & not warm like its budget Sony / Philips Digital Interface (S/PDIF) counterparts, a.k.a. Coaxial Digital Audio Cable.
5) Toslink cable is not an electrical connection so it's free from Radio Frequency Interference (RFI) / Electromagnetic Interference (EMI) unlike its budget S/PDIF counterparts. This is also its greatest strength & is ideal when using with ground loop prone hard drive / server based music systems.
6) For longer runs over 50ft, Toslink cables w'd have a clear advantage over the S/PDIF cables.
7) Amazon prices are really amazing. This cable has a Maximum Retail Price (MRP) of USD75/m as listed on Monster's website & it was last listed on Amazon for as low as USD32/m.

The bad:

1) Definitely S/PDIF cables are sturdier than Toslink cables & this sh'd only matter if U handle them a lot. In a dedicated system it sh'd not matter at all.
2) The Toslink cable's bandwidth is limited, it's even lesser than S/PDIF's bandwidth limit of 24bit/96khz. Toslink is best suited for low bandwidth 2 channel applications such as 16 bit/44khz PCM supporting formats - WAV (Waveform Audio File Format), ALAC (Apple Lossless Audio Codec), FLAC (Free Lossless Audio Codec) etc. For wider bandwidth, multi-channel applications, the HDMI (High Definition Multimedia Interface) is surely the best digital interface, even better than S/PDIF.
