YMER III
In the old Norse mythology Ymer was the ancestor of all giants from whose body the Gods created the world and the skies. The YMER III is truly a giant to rule the world of power amplifiers.
This Swedish made power amplifier represents all the accumulated experience that we at Bladelius have come to learn throughout the centuries. With its twin gigantic toroidal power transformers it generates a very solid 400 Watts at 8 ohms. Although very powerful its main objective is musicality and not only raw power. It truly lives up to the name of Oden by providing flawless speaker driving capacity, symbolizing the uncompromised design and quality that Bladelius has set to a pure standard in the industry.
The path of positive and negative current flowing through the voice coil must be completely symmetrical to accurately drive the loudspeaker diaphragm. So naturally symmetry was of a particular concern when designing the YMER III. The pursuit to find a complete balance in the amplifier circuit, power source circuit and structural aspects.
With the design philosophy Simpler is better, we reduced the voltage amplifier stage to one for the shortest signal path possible. YMER III provides a seldom found truly balanced design without ground as reference for highest possible performance. A high performance dc servo that works outside the signal path. The input stage is run by a pair of current loaded hand matched Jfets in a foldback cascade arrangement which gives a very linear performance regardless of the level of playback. This combined with current feedback gives you an extremely fast and stable performance.
To increase the purity of the power supply and achieve a more responsive and consistent audio reproduction, the rectifier stage has been completely redesigned and an even larger European made slit foil capacitor bank of over 260.000 uF effortlessly help delivering a dynamic and smooth sound with excellent transient response for which the YMER III was designed. True to Bladelius long held design philosophy of Simpler is better, the YMER III reduce the number of components needed for the first stage down to a minimum so as to allow music to be amplified in their purest form and pass through the circuit without losing even the most subtle information.
A pair of Jfet devices carefully hand selected by our specialist in the production line was incorporated into the amplifier’s redesigned input circuit. This improves the operational stability of amplification. As a result, every production unit of the YMER II have identical performance characteristics, and the YMER II delivers identical performance between the left and right channels. In addition, the new DC servo circuit stabilizes amplification, is resistant to changes in the operating temperature and the magnitude of input signals and will also eliminate fluctuations in sound intensity. All this attention to detail ensures that these amplifiers produce a powerful, condensed sound with deep, rich bass, allowing the listener to have a truly immersive stereophonic experience.
Via a rear mounted switch the user can conveniently select to run the unit in High- or Low Bias Modes, which means a higher level of Class-A or a more standard Class A/B mode.
The chassis is made out of machined non-magnetic materials to create the lowest possible electromagnetic field for improved sound quality. The YMER III:s clean design represent both Bladelius philosophy of Simpler is better and classic Scandinavian design.
