The all new NuPrime Audio IDA-6 together with the Celsus Sound SP-1 speaker system offers great audiophile sound in a well designed, compact package that's remarkably affordable. The IDA-6 has many of the same sonic qualities as the award winning NuPrime Audio IDA-16, winner of The Absolute Sound Product of the Year Award 2015 and NuPrime Audio IDA-8, winner of he Absolute Sound Product of the Year Award and Golden Ear award for 2016 as well as the Soundstage Product of the Year Award.
The NuPrime IDA-6 consists of an integrated amplifier and digital-to-analog converter that can decode PCM 384 and DoP64 with the convenience of wireless audio in a small, handsomely designed home stereo component. NuPrime's Single Ended Class A+D hybrid amplification technologies deliver the substance and warmth of Class A amplification and the efficiency and speed of Class D technology. The IDA-6's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to believed.
*Hi-Res bluetooth dongle or NuPrime WR-100 for wireless streaming is optional.
IDA-6 utilized a design technique that allows it to perform PCM 384 and DoP64 decoding that measured up to the performance of high-end DAC. A SRC (Sampling Rate Converter) FPGA IC chip up samples the input signal to gigahertz range before it is down sampled to a fixed PCM sampling rate for ultra-low jitter and distortion rates. This classified fixed sampling rate simplifies system design that resulted in sound quality that is unprecedented for an integrated amp at this price point.
With all stages in one chassis, the IDA-6 avails itself of the shortest possible signal paths in order to facilitate low levels of noise and distortion for a black-velvet background to music. Volume changes occur in 99 precise 0.5dB increments for each input’s individually adjustable volume level. Precise level matching is a breeze, as is the user’s ability to make comparisons of music sources.
The NuPrime amp circuit improves on traditional class-D design by using a self-oscillating circuit to generate pulse-width modulation. The amplifier switches at a frequency of 500kHz, well beyond the compact disc’s 44.1kHz sampling rate. Most class-D amps switch at 300kHz or lower. In addition, a new low noise switching power supply is designed specifically to complement the IDA-6 amplifier.
The IDA-6's frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights. The IDA-6's features and specifications have few equals. Just one audition will convince you that the IDA-6’s performance is unmatched at this price point.

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!…"
