Gradient is a company which may not have the widest offer and isn't trying to fight for the title of the largest speaker manufacturer in the world, but offers some of the most interesting models on the market. Moreover, there are no exceptions to this rule - each set from Finnish factory is something special, unique, and sometimes even a little odd. In the entire history of the brand there wasn't a single moment when someone decided to design just an ordinary speaker with ported MDF enclosure, several dynamic drivers, all without any frills. Gradient is always a guarantee of original, interesting vision. In the current offer we have Evidence floorstanding speakers, entirely covered with a grille, Revolution dipole sets with a triangular mid-high module and Helsinki 1.5, which are totally crazy. At a glance you know that these are not standard speakers. However, a person who thinks that Finnish designers create these sets under the influence of strong drugs, and their sole purpose is to draw attention at the exhibitions, is completely wrong. All these inventions have a strong theoretical and practical background, and the fact that the company has existed since 1984 confirms the effectiveness of their actions.

Among the speakers we can distinguish some types made for specific applications, such as center channels, wireless active speakers or subwoofers. Each has its place in a stereo or home theater, but their makers rarely focus on a particular type of speaker. Manufacturers try to satisfy every customer and offer everything, including these very specific products. There are several specialized factories among which subwoofer specialists tend to be the strongest group. REL was founded in 1990 by Richard Edmund Lord.

Audiovector is one of the most recognizable Scandinavian loudspeaker manufacturers with a true legacy and dozens of awards. They participate in all major events, and now intensively develop active wireless speakers. The company has over 22,000 fans on Facebook and keeps up with various technological innovations. If you truly want to discover the philosophy of the company, you have to meet its founder - Ole Klifoth. This friendly man has been running the company for 37 years with the help from his son, Mads. In addition to the audio equipment, he's also interested in Scandinavian and American literature, and in his spare time he listens to jazz, rock and blues in a wooden house, deep in the woods.

PS Audio is an American company, specialising mainly in the production of the high-end power components and accessories. Especially its regenerating power stations enjoy good reputation. They convert energy from the wall socket to the DC, and then rebuild it as an ideal sine wave, thus creating a perfect electricity to supply the best audio devices, which are extremely sensitive to power quality, such as analogue and digital sources or preamplifiers. A few years ago a completely new series of components appeared in the catalogue - things like digital-to-analog converters and phono preamplifiers. Here the Americans focused on modern functionality and sound quality, so that this line has grown to five devices and two extra boards. Some time ago we saw an information about the planned launch of an integrated amplifier equipped with a full DAC, phono stage for MM cartridges, headphoneoutput and Bluetooth connectivity - all in an elegant, modern box and at an extremely attractive price.

In the era of D/A converters, streamers and amplifiers, which work almost on the basis of the perpetual motion, the loudspeakers are the last bastion of conservatives. Of course the manufacturers of speakers experiment with new materials. They work on improving improve the performance of magnets, coils and crossovers. If someone is more inventive than the rest, they install ribbon drivers, transmission lines or passive radiators, but still - the market of loudspeakers remains very classic. Most audiophile sets are based on the ideas born a few decades ago. There is nothing wrong with that, unless the engineer is able to do everything right, according to the best practices. Xavian is a Czech factory founded 17 years ago by Roberto Barletta. It is one of those companies who adhere to the great traditions of building speakers. Barletta's name doesn't sound very Czech, because he is a purebred Italian who emigrated north because of his wife. However the change of residence didn't took away the long-standing passion of building speakers.

In the times of rampant digitization and the pursuit of better sound recording formats, it's important to remind ourselves of solutions that effectively resist being relegated to the past. Sometimes we get the impression that all the modern solutions create an ever greater need to escape to a world in which one can appreciate things such as turntables, vintage hi-fi and of course - tube amplifiers. There are few music lovers who have tried tubes and emerged from this experience without any emotion. This technology offers a unique sound, but on the other hand it is difficult to deny that there is something magical in these devices. Most of them are eye-catching and look beautiful, and if we add the Italian sense of style to this puzzle, we get exactly what Unison Research has been offering for years.

Until recently Denon's catalog centered on devices almost exclusively dedicated to usage in stereo and home cinema systems - amplifiers, players, streamers and micro-systems. The offering was supplemented with accessories and a wide range of headphones, very interesting headphones, we have to say. However the increasing trend pushing many sectors towards mobile devices caused also a change in the catalogue of this Japanese company, causing an avalanche of propositions with different purpose. So last year we saw a few novelties, like the CEOL series of systems, the Envaya speaker looking like a lady's purse, the elegantly sleek soundbar DHT-T110 or the HEOS wireless speakers. But Denon seems not to be stopping there, as they recently presented their first DAC/headphone amplifier. This device is not only small, but also looks splendidly placed on a desktop.

Marantz is a company which managed to successfully penetrate the area of home cinema, receivers and modern streamers while preserving audiophile roots and an aura of exclusivity at the same time. It seems that they've found a recipe how to balance between the world of modern technologies and this what is proved, classic and desired by the lovers of high-quality sound. If you are interested in the gear from previous ages, and if you like internet profiles with vintage audio, you have surely seen loads of Marantz's equipment there - beautiful amplifiers, tuners with backlit scales and oscilloscopes, CD players with massive trays and advanced optics, all in metal, wood and glass. No wonder that in times of omnipresent plastic a retro fashion came back, bringing stereo equipment to where it should be.

Some time ago we were contacted by the Auris Audio company, after we saw their products at this year's High End show in Munich. These unknown tube amplifiers from Serbia accompanied by small Boenicke Audio showed such an addictive sound, that we were very enthusiastic about having a chance to listen to these devices more closely. It was unusual situation and the surprise is all the greater, because this fresh company presented several other products - preamplifiers, integrated amplifiers, power amplifiers and even a couple of DACs and headphone amplifiers. We could have expected that at least dozens of distributors will be willing to promote this brand in their countries. Indeed Auris Audio aroused so much interest that we had to wait a few months for the first amplifier for the review.

Nic Poulson is a telecommunications engineer who studied and worked at the BBC in the eighties as a sound engineer. After leaving the BBC in the early nineties and further developing his passion for audio equipment, Nic has become a well-known designer of electronic circuits with Trilogy Audio Systems company. He also designed and implemented runway lighting systems at various airports. For us the most important thing is that he was one of the first people to notice the problem of power supply systems. That's why he founded IsoTek - in order to deal with this in an appropriate manner.
