Aesthetics and Build Quality:

The Ni is about the size of a 9v battery, and looks very plain. All black but with the company branding in white on it along with white arrows showing the input/output sockets; sitting between these sockets is an LED. On the other end you have a micro-USB for charging, and that is it, no buttons or switches, just a block with sockets on it.

The build quality is superb, it may be made out of polycarbonate, but it sure is well put together. Tolerances are incredibly tight and the housing is very well put together, along with the fact that the 3.5mm sockets are tight and of very high quality. All of this put together makes the Ni a solid little amp that should easily be up to the task of daily use.

Features:

The Ni does not have an on/off switch or volume control, the sockets sense when a source and headphone are connected and power the amp on. Volume is controlled by the source, and the Ni has a fixed gain of 6.5dB. It will supply 150 mW into 50 Ohms, 250 mW into 32 Ohms, and 270 mW into 16 Ohms. This makes it suitable for most headphones that are used for portable use, and some harder to drive models too.

The battery charges from flat to full in only 30 minutes, and you can expect around 9hrs of battery life from a single charge. The input impedance is very high which means it almost totally bypasses the internal amp of your source. The sockets are TRRS so when you are using it with a mobile phone, mic and controls will still pass through to the phone. The Ni is also engineered to be nearly completely RF and noise interference free.

Sound:

Well Periodic have put a lot of thought into this tiny little amp, so you would hope the results pay off.

Well rest assured all that work didn’t go to waste, the Ni does exactly what it sets out to do without fault. Phone outputs are usually pretty poor, and this little amp really does bring an improvement, and not just in terms of volume.

It goes beyond that and you get a nice quiet background with very low noise, alongside an increased sense of control and responsiveness. Lows sound tighter and more articulate, the midrange sounds better separated and airy, along with effortless extension up top. Of course, a lot of this will depend on the headphones you plug in, but with the Ni you can use a wide range of earphones to headphones and get the same quality performance that a phone simple cannot give on its own.

The Ni doesn’t inject a signature of its own, it does not have any additional bells or whistles, it purely amplifies the signal. But it does so in a very clean and precise manner that is perfect for those with low powered sources or poor headphone outputs.

Conclusion:

If you are looking for a boost in power, or a step up from your phone’s headphones output, the Ni is the perfect solution for on the go use. With great battery life, quick charging time and excellent sound quality, what’s not to love?

It has a USB tybe C socket on the top and a 3.5mm headphone jack output on the bottom, on the front an LED will light up telling you the device is on and what sample rate is playing.

Sound Quality

The UP is so clean, so clear it is hard to go wrong for the price. I am a DAP user, and don’t use my phone for music as I like having files stored locally. But the trend to not want to carry an extra device nowadays has grown and also Apple did away with the headphone jack so the market for portable DAC/Amps is booming.

There are plenty out there, but few that offer full DSD support and an ES9018 DAC chip for this price. The Shanling UP may only be able to output 35mW @32 Ohms, but it gets loud and driver easy to medium hard to drive headphones.

From IEM’s to portable full-size headphones you will be guaranteed to get much cleaner and better separated sound with the UP.

• Bass

The bass is tight and controlled, with precise kick and good body to back it up, the bass notes also decay as they should.

• Mids

There is no added body to the lows, this means the midrange is allowed to shine and it does, with vocals coming across clean with excellent detail retrieval. There is also plenty of air around notes which allows you to pinpoint each and every part of the recording.

• Treble

The treble is well extended without any harsh metallic tone to it, what is best about the highs is their imaging, the placement within the soundstage is critical and this little device has managed to get it spot on.

Conclusion

The Shanling UP is a superb High Resolution DAC/Amp for portable use, if you have some good headphones, you are not hearing their full potential out of a phone. This will change that, the UP with give you the clarity, detail and soundstage that your phone simply cannot.

Even being used with a PC there is a substantial upgrade from the on-board audio, so this can be used on your morning commute with your phone, then plug it into your PC at work and enjoy the same quality of music.

The post Cypher Labs Theorem 720 DAC – Announcement appeared first on HiFiheadphones.

John Cadman, Graham Slee’s production manager, reported that the delays have been caused by a shortage of the Voyager case component. The case is manufactured outside the UK (in Canada) and the shortage of this one component has held up production.

About the Voyager

Graham Slee produced the Voyager headphone amplifier to be used with MP3 players, such as the iPod, and other portable audio devices. The Voyager amp simply plugs into the headphone output of the audio source and you plug your headphones or earphones into the Voyager’s headphone out.

Alternatively the Voyager can be connected to an iPod with a cable that connects directly to the iPod’s dock connector. This setup provides a better quality line level signal than the headphone output socket.

About Graham Slee

Graham Slee have a long standing reputation in the British audio world for producing phono pre-amplifiers (for vinyl record playing turntables) and high quality desktop headphone amplifiers, such as the Graham Slee Solo.

The Solo headphone amp is popular in broadcast and recording studio environments. The Voyager is the first venture into portable headphone amplifiers for Graham Slee and has been very well received by the audio and HiFi press.
