You will be proud to showcase the NuPrime IDA-16 in a place of prominence within your room as its sleek, low profile chassis and understated elegance are sure to draw the attention of your most discriminating guests. Whether your preference is black or silver finish, the NuPrime IDA-16's simple, modern style is certain to find broad approval as it politely augments any decor.
Starting with complete integration of all necessary stages within one chassis, the design inherently ensures the shortest possible signal path, which thereby results in vanishing levels of noise and distortion to create a jet-black backdrop upon which your recordings literally unfold before your ears. Mere vocals are transformed nigh unto emotional experiences while the upper registers of instruments become the shimmering highlights of a live performance. In all, its crystalline transparency, holographic imaging and fatigue-free sound will allow you to finally relax and experience the music as it was meant to be, while almost forgetting the NuPrime IDA-16 is even there.
As you continue through the product description and reviews, you will see that the NuPrime IDA-16's many innovative features and exemplary specifications are truly impressive. More importantly though, just one listen and you are certain to discover the NuPrime IDA-16 to be a true hallmark of audio performance by elevating music playback and visual style to a level seldom experienced at any price.
Following in a long tradition of world-renown audio excellence, the NuPrime IDA-16 combines leading-edge audio technology with unprecedented innovation, style, and value. As the world's first fully integrated digital amplifier offering 384K & DSD decoding (2.8MHz, 5.6MHz, 11.2MHz), from its digital or analog inputs to its 200-Watts/Channel speaker outputs it delivers the purest, most natural sound modern audio technology can provide, while also providing the widest support for the latest High-Resolution music formats.
Such deafening silence is further augmented by the NuPrime IDA-16's innovative volume control; a feature based upon advanced, thin-film switched-resistor technology that places only a single resistor in the signal path at any volume setting. Volume adjustment is conveniently achieved in 99 precise, 0.5dB increments and is further complimented by providing individually adjustable volume for each input. Precise level matching of your various sources becomes a breeze and makes comparison between them equally so.
Completing the ensemble is NuPrime's proprietary variable frequency Switch-Mode Power Supply (SMPS) technology. For thundering, authoritative bass performance, the NuPrime IDA-16's innovative supply and its Cross-Matrix Array (CMA) capacitor bank are capable - upon demand - of delivering extremely high current to the amplifier's output stages. In addition, the supply's 600 kHz switching frequency and output voltage actually vary in real-time based on the instantaneous demands of the music. The result is unprecedented transient speed and an almost shocking level of dynamic impact that renders percussive instruments as though they were suddenly attacking outward from beyond the blackest depths of a phantom stage.
Such highly responsive behavior achieves extremely low Total Harmonic Distortion + Noise (THD+N) levels of less than 0.004% while attaining a maximum system efficiency of up to 93%. Adding the NuPrime IDA-16's stratospheric frequency response up to 80 kHz.

"...when you consider the NuPrime IDA-16 has an advanced DAC built in, which will play virtually any digital recording available today, it’ s an even better value. Of course, if it didn’ t sound good, it wouldn’ t be a good value, no matter how low the price was, but it sounds excellent...The NuPrime IDA-16 DAC/amplifier along with the KEF LS50 speakers made a system that, if you’ll pardon a tired reviewer cliché, punched far above its weight. So to return to the question left open in the first paragraph: Yes, the NuPrime IDA-16 DAC/amplifier can indeed be called a bargain. Highly recommended..."

"...This quietness was a particular advantage when I listened at low volume levels, something I usually find uninvolving. Not through the IDA-16 -- my music was just as captivating as at high volumes. Against the NuPrime’ s jet-black backgrounds, all of the dynamics of my recordings were present at all volume levels, making the IDA-16 one of the few amps I have enjoyed for late-night listening... IDA-16 is an exemplary integrated amp-DAC with rock-solid imaging, transparent sound, and tight control of bass..."

A DAC, a headphone amplifier and a preamp in one easy to use portable device. The NuPrime uDSD connects your personal computer to your home stereo, desktop sound system and headphones. The uDSD features direct DAC out, i.e., fixed-analog out, in order to provide better overall sound quality, and in particular, better-sounding DSD playback. The headphone circuit, built on a sophisticated balanced design, provides the uDSD with the ability to drive almost any of today's headphones -- a feature that can also be used to drive active speakers. This makes the NuPrime uDSD incredibly versatile and powerful allowing you to enjoy your music to the fullest.
The uDSD is capable of supporting up to DSD256 and PCM384 with incredible specifications offering the highest quality sound. Compared to similar DACs in the marketplace, the uDSD has far greater capability and improved sound and it comes in a beautiful jewel-like enclosure. The uDSD is one portable DAC and headphone amp you will want to experience for yourself.
The NuPrime uDSD is a next generation desktop DAC/amplifier and is often compared to the NuForce uDAC which many audio enthusiasts have loved for years. If you want to enjoy the latest in high resolution formats with less distortion, greater dynamic range, impressive signal to noise ration and great headphone output, then consider upgrading you older model uDAC to the new uDSD. With greater capability and improved design, the uDSD provides excellent sound.
NuPrime audio products are high-performance audiophile components that offer sound quality well above their price point. Indeed, NuPrime's other audio products have been reviewed in Soundstage and The Absolute Sound and are considered some of the current best in the audio world, regardless of cost. The most recent DAC-10H and ST-10 combination as reviewed in The Absolute Sound are said to be some of the best audio components reviewer Steven Stone has ever heard, price no object. It perhaps not surprising then, that the NuPrime uDSD high resolution digital-to-analog converter and headphone amp also performs well and far better than it's $179 suggested retail price would imply.
The uDSD is a new "audiophile-grade" DAC/headphone amp, built to connect to your computer via USB. Music is typically recorded in 24- or 32-bit PCM or DSD format at the recording studio and then converted to a lower resolution format for distribution, typically via CD or MP3 download. Those CD quality digital files, are recorded in 16-bits with a sample rate of 44.1 kHz, but PCM-encoded WAV audio files stored on a computer's hard drive might have a resolution of up to 24-bit/192 kHz or beyond.
The uDSD is certainly capable of supporting the latest high resolution digital music formats at up to 24-bit/384 kHz, but is also capable of native Direct-Stream Digital (DSD) decoding up to DSD 256 (Quad-DSD). This small device is capable of decoding virtually any known high resolution audio format in either PCM or DSD. An increasing number of download sites provide both high-resolution PCM and DSD in a number of sample rates but with the uDSD, you will be able to play them all. DSD, which was originally designed as an archival format for studios, has been making a comeback in recent years thanks to the introduction of computer audio systems.
The headphone circuit of the NuPrime uDSD offers a stereo output of 140 mW at 32 ohms, which is more than ample for most of today's headphones, a dynamic range of 98 dB, signal-to-noise ratio of 112 dB and total harmonic distortion of less than 0.01 percent. With these impressive specifications, the NuPrime uDSD can outperform all comparable products offered on today's market. As a start to a new desktop, an office headphone stereo, a home audio system or as an upgrade to those who love the original NuForce uDAC, the uDSD offers more in every department.
The NuPrime uDSD is quite small and can easily fit in the palm of your hand or in a pocket to transport it wherever you need your music. It's machined all metal finish is exceptionally good and the quality of the volume control and the connections are fantastic. It's rugged yet nicely finished and it feels solid and well constructed, as all NuPrime products do.
The uDSD comes with Coaxial S/PDIF and 2V RCA Analog outputs for compatibility with a broad variety of systems. With its native DSD-format decoding capability, uDSD is ideal for upgrading existing high-end non-DSD DACs. With the USB port on the side the uDSD is powered by the computer and requires no additional power supply.

The Celsus Gramo One is a reference-grade open-back in-ear headphone that sits comfortably on the outer ear. With the portability of an in-ear headphone (IEM), the Celsus Gramo One’s exceptional sound quality equals or betters the most highly regarded over-ear headphones. It is designed for long listening without the drawback of the weight of over-ear headphones or ear pressure of in-ear earphones.
One’s first – and enduring – impression is of an overwhelming, three-dimensional audio experience that can fairly be described as a virtual live event. The proprietary 16mm Celsus sound transducer produces a sense of space, depth, detail and dynamic range as impressive as that of an audiophile’s dream sound system. A mesmerizing midrange and solid bass are among the more impressive of the Celsus Gramo One’s signature qualities. It has a seductive vocal textures rarely found in high-end earphones.
The term reference-grade typically connects with a few widely celebrated over-ear and on-ear headphones. Their common drawback – and it’s a serious one – is weight and size as principal contributors to listener fatigue. In recent years, a few in-ear headphones have achieved reference-class status. Again, as a drawback, IEM devices suffer from an ultimately fatiguing music-in-the-middle-of-one’s-head effect along with the excessive ear pressure that inevitably accompanies prolonged listening. The Gramo One, a different animal entirely, avoids these pitfalls through creative engineering.
"…I'm usually not a fan of earpieces that rely on the size of your outer ear to stay in place, but these Gramo Ones turned out to be pretty comfortable in everyday use. As for sound, once you get the placement right, the 16mm drivers deliver great, accurate bass and a balanced sound…"

"...Right away there was a healthy amount of bass greeting my ear, and I don't mean the flabby wubwub kind. Slightly boosted but clean, and strong down to about 60Hz before I noticed any significant rolloff. There was still decent response down to 40Hz...The open back gives the bass and good distortion performance. Covering it with your fingertips immediately drops the bass and cranks your distortion up..."

"…I always expect that in-ear headphones will be a shadow of the over-ear version but in this case I’m surprised at what I’m hearing. This is far superior to my iPod and Apple headphones. I guess that should not come as a surprise but I had never tried an in-ear headphone other than what got shipped with my iPod or my iPhone. I must say, it’s really good…The sound is smooth, absolutely full range, it's rich and oh so easy to listen to. This is not my typical Apple musical experience. This is more like being at home. It’s portable luxury!…"
