Posted on February 1, 2024 by Joe Marr

The Cambridge Audio CXN100 is a network music streamer that aims to deliver stunning sound quality and extensive streaming features. It is the successor of the multi-award winning CXNv2), which has been one of the best music streamers in the market for years. The CXN100 claims to be a complete mechanical redesign of the CXNv2, with a new DAC, a new StreamMagic Gen4 module, and improved performance and functionality.

The CXN100 has a sleek and elegant design, with a lunar grey aluminum chassis and a ‘floating’ effect. It has a large and clear color screen that displays album artwork and track information.

Performance

First up, Matt Haeson’s “Hallucinogenics” (featuring Lana Del Ray) is truly a versatile track for evaluating audio equipment. The balanced distribution of low, mid, and high ranges, combined with Lana and Matt’s vocal interplay over the gentle strumming of an acoustic guitar, creates a perfect testing ground for audio fidelity. Lana Del Ray’s breathy and emotive delivery, juxtaposed with Matt’s nuanced vocal variations, demands a system that can faithfully reproduce these delicate vocal nuances. As the chorus arrives, deep thunderous bass and hints of tambourine emerge, adding further layers to the sonic landscape. The CXN100 impressively maintains the clarity and separation of each musical element, ensuring that the listener can fully appreciate the intricacies of the song without any loss of detail or muddying of the sonic presentation.

Furthermore, the precision and agility of the CXN100 are on full display as the song progresses. In the bridge, subtle background harmonies interweave with the main vocals, requiring a system with excellent imaging capabilities to render these subtleties with precision and accuracy. The CXN100 rises to the occasion, offering a wide soundstage and pinpoint placement of individual vocal and instrumental elements, fostering a captivating and immersive listening experience. The delicacy of the acoustic guitar is also worth noting, as the CXN100 unveils the rich tonal character and intricate fingerpicking details with finesse, preserving the authenticity and organic quality of the performance.

This track’s dynamic range and textural complexity truly put audio equipment to the test, and the CXN100 emerges as a formidable contender, meeting the demands with poise and finesse. It underscores its capability to faithfully reproduce the artist’s intent and deliver a compelling sonic experience that resonates with the listener. As such, “Hallucinogenics” becomes not just a piece of music but a journey through sound, wherein the CXN100 serves as the reliable guide, navigating the listener through the intricacies and subtleties of the musical landscape.

Next, we listened to the Eagle’s Hotel California from 1994’s When Hell Freezes Over. We streamed this song from a Roon music server at 192khz. The CXN100 easily handled the stream with no detectable delay or jitter. We like this version of Hotel California for the opening, which slowly introduces each member of the band through their individual contributions much to the delight of the live audience. From Timothy B. Schmit and Don Felders percussion and harmonies, to Don Henley and Glenn Fry’s distinct vocals, the CXN100 faithfully reproduces each and every element of this classic.

One notable aspect is the expansive and tight soundstage delivered by the CXN100, which truly enhances the immersive quality of the music. The rendition of Don Henley’s vocals as “smoky and weathered” adds a dimension of authenticity, while Joe Walsh’s distinctive playing style is skillfully presented, showcasing the CXN100’s ability to faithfully represent the musicians’ artistry.

Overall, the CXN100 excels in delivering a superb rendition of this iconic song, effectively capturing the intricacies and nuances that make this live performance of “Hotel California” a timeless classic.

Conclusion

The CXN100 from Cambridge Audio truly represents a leap forward in the realm of network music streamers.

Review: IsoAcoustics GAIA Speaker Isolators

Posted on February 4, 2023 by Joe Marr

IsoAcoustics GAIA is a series of speaker isolators designed to minimize the impact of the listening environment on a speaker’s performance. Specifically, it isolates the speaker from internal reflections generated by the flooring supporting the speaker. The result is greater sound clarity, an expanded sound stage, and reduced vibrations in the surrounding listening environment.

I discovered GAIAs in a Facebook post while researching how to reduce vibrations in my Home Theater space in my finished basement. The basement is constructed of concrete below grade and wood/brick above, with a concrete floor covered in Luxury Vinyl Plank (LVP) flooring and a drop ceiling with sound-absorbing tiles. The walls are well-insulated and treated with Acoustic panels from ATS Acoustics. Even with the amount of insulation and acoustic treatment, I still had vibrations I couldn’t track down. I eventually determined that they resonated from within the subwoofers (2 x Martin Logan Dynamo 1600x) and tower speakers (2x Martin Logan 60xti).

In talking with people in the Facebook group, the recommendation was to decouple the speakers from the concrete/LVP flooring by installing some isolation technology. I first experimented using the rubber feet that came with the speakers and then the included spiked feet. Neither of these seemed to help, so I was skeptical. However, I did some research and found isolating the speaker from their environment is a common practice in professional recording studios. Methods range from installing bases for the monitor speakers to sit on to building the studio on top of giant spring/rubber isolators.

I received many suggestions, but the one repeated the most was IsoAcoustics GAIA Speaker Isolators. After consuming as much information on the product as possible, I ordered some for my subs and towers.

IsoAcoustics is a Canadian manufacturer of isolation products for the audio industry and has been in business since 2012. The founder, Dave Morrison, has been designing and building radio and television studios for the Canadian Broadcasting Corporation (CBC) for 20 years. The GAIAS are feet that replace your speaker’s existing feet and are constructed with a dark stainless steel shell and a thick rubber-like foot that protrudes from under the surface. The rubber-like foot can move up, down, forwards, backward, and left to right. It has a concaved bottom that provides a suction cup-like surface to provide some resistance to sliding on the floor.

The feet are straightforward to install. Remove your old feet, and install the new ones. There is one caveat. The feet have the IsoAcoustics logo on them, and it serves an essential purpose. The feet are directional, so the logo needs to be facing the same direction as the drivers in your speakers. So, the logo either needs to be facing forward or backward. The feet come in a kit of 4, enough for one speaker. There are three sizes of feet; which one you choose depends on the speaker’s weight. The IsoAcoustics site provides a tool to determine the correct size. Don’t simply buy the largest feet. GAIA 1 supports up to 220lbs, GAIA II supports up to 120, and GAIA III up to 70. Due to the nature of the rubber foot, under or oversizing the foot could have unintended consequences.

For my needs, I ordered GAIA III for my subwoofers and GAIA II for my tower speakers. Each comes with 4 feet, three mounting bolts covering the most common hole sizes for feet, and a tool to help with installation. If the supplied bolts don’t fit your speakers, IsoAcoustics will ship you the ones that do.

After installation, I realigned my speakers for my sitting position, grabbed my remote, and sat down. I expected to hear a slight difference in how my system sounded. However, the results blew me away.

I put my copy of Top Gun Maverick in the 4k player and watched the opening sequence. I was amazed at the details I could hear. The change in sound was remarkable. The bass was no longer muddy, the mids were crisp, and the sound stage was more defined. I could hear movements transitioning from left to right that I could barely hear before. Most importantly, the audible vibrations I had become obsessed with were virtually eliminated. I had seen this movie ten times before, but I became consumed by the details of the soundtrack I could now hear.

Listening to music had the same result. I picked Hotel California from the Eagle’s live album, Hell Freezes Over. The quality of the sounds was equally impressive. The mix between left and right is more defined, allowing one to better hear each instrument individually during the first 2:08 of the song.

I highly recommend these to anyone looking to improve the overall sound quality of their Home Theater. As of the writing of this article, GAIA III was $199, and GAIA II was $299, so they are not cheap. However, considering the cost of other alternatives and the impressive performance of the product, I feel it’s worth the money.
