Year 2012. Two Awards for best sound of show

At the German High End Show in Muenich, the Swiss company COLOTUBE has received two awards for the 'Best Sound of Show', using the EML 300B, EML20B driver tube, and EML 5U4G mesh rectifier.

Quoted from 'Rated at 95dB, the Colotube 10wpc amplifiers had an easy job of driving these speaker and did so very well. With just three tubes and avoiding the almost ubiquitous small driver tube by favoring a full-swing 20A instead—proving fearless of higher gain and voltages—the Colotube mono's sounded liberated from the tubular confinement often praised as tube sound. Together with the 5U4G rectifier the driver and power tube are supplied by Emission Labs ®. The tranquility and lightness of this room combined with what we in hindsight realized was our best sound of the show this year'.

Year 2012 Award # 2

A Russian National prize 'Product of the year 2012' was won by the company STARLINGBOX using the EML 300B Mesh.

The award was in the category 'Top High End', for the best acoustic system made in Russia.

Organized by the MIDEXPO Company. (Opens in new page)

The company Starlingbox builds a unique system, based on the famous Lowther PM2A drivers, here in a d'Appolito configuration. The driver tubes for the Lowthers are the Emission Labs ®300BM (true mesh wire tubes) giving 5Watt per Channel. High frequency support comes from Fostex Super Tweeters, driven by it's own tube Amplifier, with a 6AG7 tube at 2Watt per channel. Bass support comes from a pair of dipole speakers. The specialty of dipole speaker box is, they can be operated below the resonance frequency of the speaker chassis itself. Thus allowing the use of only 12' speakers, and yet the system can go down to 20Hz. Interesting is, even for 20Hz, the cabinet of a dipole box is the same size as the speaker chassis itself. This explains the relatively small size of these boxes.

These kind words, we received from Dmitry and Alexander Kudriavtsevs, of the company Starling box:

'Our audio acoustics system won won the national prize as the National Top Hi-End Product of the year 2012! You can see some details of our products and the Show events here The most popular Russian journal Stereo/Video in June issue wrote that we had the best sound at the Show. But we couldn't do it without the electronics of our production based on the components delivered by your company. First of all these are the EML 300BM tubes of the unprecedented audio quality. Many of the leading audiophiles and musical experts said that they couldn't imagine that the audio system could sound so natural, delicate and energetic with deep holographic scene. Thank you very much and our congratulations to the designers and engineers from EML!'

In the VIP saloon which is larger than 200m², where was represented another system of our production with twice the power (using 300BXLS from Emission Labs ®).
