Unique Innovation Technology Perfect Music Purifier (PMP) Interconnect

Minor Miracle or Stroke of Genius

I am an audiophile, not an engineer, but I know after 55 years of searching for wire that is neutral like Seinfeld… sounds like nothing at all… the UIT wire gets extremely tantalizingly close. It is revealing in ways only the best and most expensive concoctions can achieve and is as dynamic as the best of the bunch. It will do subtle and rich, warm and fast, sophisticated and room shattering without breaking a sweat. I was unable to identify any colorations directly associated with the UIT wire runs.

I will tell you this, depth and sound-staging are as big as your source allows. Imaging is rock-solid. They are never etched sounding, but smooth as a baby’s butt. Though I would call these a stroke of genius, I am not ruling out a minor miracle.

Adding just one pair in the circuit appears to clarify and enhance the music and mitigate system problems. Placed between DAC and Preamp resulted in the biggest boost in goodness, neutrality, and definition. In other words, “closer to the source” seemed to yield the largest gains. You can use that as a point of departure in your own experimentation with the UIT cables. No spot in the system seemed to be a problem for the UIT and they got along well with every cable brand in other parts of the circuit just fine.

A complete run of the UIT wires from the turntable output and in the digital circuit to preamp and amps was a stunning leap in performance. Speaker wire brand was irrelevant, and tube or solid-state gear made no matter. With all UIT, you got the best of what was possible in your gear with remarkable, cutting-edge neutral clarity that you would have to hear to believe.

Not long ago I identified two newcomers to the cable party under $2000 per meter that over-achieved musically. Now that I have heard and evaluated the UIT wires, those others may be musical, but my estimation of their accuracy has been downgraded by the superior performance of the UIT. I compared the UIT to one wire that clearly bested the UIT by a small, but telling margin. Yes, it did have even more definition, and was slightly sweeter overall. But the problem is that this marginally superior cable sells for $10,000 per meter! No kidding! So yes, there are more expensive wires on the market that can do this amazing disappearing trick in your system. But none are under $2000 per meter—and the UIT cost half of that!

 

Unique Innovation Technology Perfect Music Purifier (PMP) Interconnect

Summary

The Unique Innovation Technology Perfect Music Purifier (PMP) Interconnect Series has taken connectivity in the under $2000 per meter category to a new supreme level, maybe even to the highest level. I will leave that conclusion to you, dear reader, to decide, but if you were considering any interconnects up to that cost, the UIT are your first and last option, in my judgement. Hell, the UIT cables cost half as much as the previous $2000 entry point for high-level performance high-end cables that I had previously assumed!

I will soon have what may be the finest, most neutral phono cartridge in for review, and how the UIT wires perform with this mega-buck transducer will be most telling. Mitch Ko may have stumbled a bit with the fiber cables of yesterday, but his UIT cables are winners in every way, and a bargain unlike I have never seen.

The Unique Innovation Technology Perfect Music Purifier (PMP) Interconnect Series has my highest, unequivocal recommendation.

Spectral Audio DMA-200S

The DMA-200S High Resolution Amplifier shares with other Spectral components, the creative uncompromising use of edge-of-the-art technology, dedicated precision manufacture and Spectral’s experience with live sound at recording sessions. From extensive listening and design experimentation, Spectral has consistently pioneered component systems having fast settling, high-speed circuit architecture. These have invariably outperformed more traditional, often cumbersome high-end design methods to achieve superlative detail, staging and listener involvement. Indeed, test methodology simulating music waveforms and hearing acuity confirm that quickness of response and rapid signal extinction when reproducing complex dynamics are mandatory for accurate music reproduction. Only then can one preserve instantaneous waveform accuracy to prevent cover-up of delicate musical signals by previous events. Construction and performance of the Spectral DMA-200S High Resolution Amplifier for this demanding criterion and resulting sonic resolution are unmatched among contemporary high-end amplifier designs.

Avalon Acoustics Compas for sale

We are selling our brand new in the box Avalon Acoustics Compas loudspeaker.

Inspired by the rhythmic time signature patterns of flamenco music, our COMPÁS illuminates the fundamental structural elements of metre and impulse in all musical genres. Primarily characterized by its dynamic and percussive rhythms, the COMPÁS delivers a disciplined performance with high transient speed and clarity of image definition. This constant Q design generates critically damped driver resonances from octave to octave throughout the audio spectrum. With a Q of 0.5 ringing and transient smearing is eliminated.

Control networks within the crossover designed specifically to target resolution and ambience retrieval under high current conditions are the heart of COMPÁS. Its unique ceramic/honeycomb woofers deliver an authoritative low frequency response with unsurpassed transient accuracy, carefully blending with the highs for a “true to source” sound reproduction. Proprietary low jitter circuitry clarifies image boundaries to a high-resolution standard suitable for professional monitoring where microphone placement and phasing are critical. Utilization of the same diaphragm materials throughout the array adds to the continuity of harmonic structure in a crisp, seamless musical presentation devoid of stored energy; its rock solid imaging presented with a palpable density through accurate and colorful harmonic structures.

All AVALON ACOUSTICs loudspeakers are engineered and built to the highest standards in the audio industry. Handcrafted in Boulder, Colorado by dedicated craftsmen and technicians, each COMPÁS is measured and matched creating perfect symmetry and coherency. Before leaving the factory each of our masterpieces is subjected to a demanding array of quality control and testing procedures to assure flawless and consistent performance. Our creations are a work of art in which we take great pride, designing and building each one exclusively here in the foothills of the Rocky Mountains.

THE ABSOLUTE SOUND’s 2014 OVERALL PRODUCTS OF THE YEAR Berkeley Alpha DAC Reference Series

image

The Berkeley Alpha DAC Reference Series is not only the absolute state of the art in digital-to-analog conversion; it also goes far beyond even this superlative to redefine what’s possible in digital playback.

This is a landmark product in that it crosses a threshold of sound quality and musical expressiveness that renders moot the idea that digital can only aspire to mimic analog rather than offer its own set of virtues.

The Alpha Reference is simply stunning in its ability to render instruments as real- sounding objects in three-dimensional space. This startling quality is made possible not just by the Reference’s spatial precision, but also by the timbral vividness and extraordinarily high resolution of the tiniest micro-details. What’s more, the Reference performs this magic trick on all instruments simultaneously, even in the most dense
and complex passages. This unprecedented (for digital) quality allows the listener to easily follow individual musical lines in a way never before possible from digital. Bass performance is also outstanding,
and different from other DACs. The Alpha Reference’s full-bodied bottom end not only provides a solid tonal foundation; it is also exquisitely textured and nuanced.

Note that the Alpha Reference omits a USB input and DSD decoding by design so as not to compromise performance. To play music from a computer, you’ll need Berkeley’s also-outstanding Alpha USB USB-to-SPDIF converter ($1895). Speaking of which, this USB converter can significantly improve the sound of your existing DAC by isolating the computer from the DAC, receiving USB data with a state- of-the-art interface, and by reclocking the output with high precision.

The Alpha DAC Reference is an unqualified triumph, and an easy choice for The Absolute Sound’s Overall Product of the Year Award. (246)
