Overview of the active interconnecting cables Burson Audio Cable

The Developers of Burson Audio just do not like to sit around all the time gushing of unexpected ideas. Most interestingly, the ideas they have are quite simple, but really useful. A good example of this would have had on the review . Now a new idea — interconnects with active amplification.

The whole idea really obvious. Modern mobile phones is the faithful companions of many people, and, of course, to most listeners keeps your music library. However, mobile phones are limited by food, so almost never in them do not put powerful amplifiers, because for a simple headphone plug a lot of power and is not necessary. So trying to use a smartphone directly with a serious amplifiers usually lead to not very good results, the latter used to input a stronger signal. Then comes to the rescue and .

In fact, it is a simple wire-milochik with built-in amplifier. With one hand placed 3.5 mm Jack for the source, with the other pair of either RCA or a single 3.5 mm plug, depending on input on your amplifier. The aluminum block in the middle hides the amplifier based on SS V5i.

As you can see, all ingenious is simple.

However, the question remains, what portfolio has a wire to the inputs and outputs in the form of a pair of RCA? According to developers, the option of RCA helps in cases where the signal source (DAC or player) is not very compatible with the amplifier impedance. In this case, Cable+ assumes the role of active negotiation element that corrects the problem. I version with two RCA not tested (but would like), but according to reviews online, it works well and copes with its task.

Burson Appreciated your cable is 150 $ for any version, you can purchase it directly on their website. The price includes international shipping and 2 year warranty, extendable to 5.

Burson Initially raised money for the first batch by using crowdfunding, then to the idea I was sceptical, but closer acquaintance allowed me to dispel the skepticism.

Packaging and design

As for the cable box acts as a plastic container with a latch, about the same, but much smaller, came and hybrid op amps the previous survey. Neatly fixed inside the cable itself, as well as simple accessories: simple MicroUSB cord for power and is absolutely trivial, charger from China, acting in this case, the power supply unit. Connectors for protection against adversity is covered by the silicone caps.

In General, the design of this cord is very simple: a compact aluminum block with amplifier made in the form of a parallelepiped with rounded edges. On the one hand it goes a long cable «login», on the other — more short «output». End is inserted into a MicroUSB power cord. Decorative «plus» top has pretty bright blue led indicator.

The wire made in black silicone insulation, they are flexible and comfortable. Connectors — high-quality and pleasing stylish chrome housings.

In General, the device is very simple, and hooking it up the slightest not working. Turn right ends at the right of the device powering up and everything, «it's alive».

Sound

To test the device following equipment was used.

the
    the
  • iPhone 6 Plus and as sources
  • the
  • as a booster
  • the
  • Headphones: , , , , and others.
  • the
  • Recording high-resolution Lossless-formats (Dr. Chesky have The Ultimate Headphone Demonstration Disc and others)

Despite my love for Apple technology, iPhone, I have not seen as the source of the sound (so, incidentally, to the disappearance of the 3.5 mm connector, apparently, were very positive). Sounds Apple products not that bad, probably closer to «OK», but to «» does not hold. Actually, the problem here is General enough for most normal smartphones: flat imaginary scene, hollow bass, crisp treble. Good the amplifier is, of course, tries to compensate for this, but it turns out not always. The same NuPrime can really play better with a good source.

To honor Cable+ it is worth noting that it is well weakens almost all of these problems. Bass are deeper, which gives them such a missing weight. Of course, not the best study of the textures is not correct, but the bass at least loses its effect «void». Treble sound easier and more detailed, which gives the effect of expanding the imagined scene, and of the elaboration of the depth becomes slightly better, although still not up to the players of medium and high level. In General, most of the changes are not huge (unless the bass is really noticeable changes), but the amount they change the sound significantly, it makes a good step forward.

The Improved bass iPhone gave me the idea of another experiment. Not so long ago in my hands visited HiFiMan Begin player from all sides is nice but plays a little lighter than I would like. In General, as you can guess, and he Cable+ benefited by adding a bit of bass in both quality and quantity. With this amendment Begin began to sound in the stationary system quite at the level of their youngest of the older brothers from HiFiMan.

Insights

To summarize, we can say that the Burson did a really good device. Simple and convenient booster, once combined with the right wires, allows you to easily connect your smartphone to the main audio system and use it as quite a decent sound source. Of course, this scenario is not often found in everyday life, but when faced with the necessity of such connection, Cable+, probably the best way to do it.
