Forstærker sæt med monoblokke på 2x40 watt Forforstærker med fjernbetjening i absolut topklasse med fine tests. Blandt andet skriver Hi-FI World:" Outstanding - Among the best"

I was astonished by the elegant sound of this 300B preamplifier, as well by its reasonable price. There is always room for improvement for preamp with 300B tubes, a challenge which has been mastered in this pre-amp through its workmanship. This preamp exploits all the merits of 300B tubes to the fullest. Its pricing is more than reasonable given that the cost of the used materials and the crafty workmanship. It is highly unlikely that except for the Chinese mainland, there will be a factory in the current audio world that can produce a 300B preamp to such a reasonable price with similar technical specifications.
This 300B preamp hooked up with the 300B/845 flagship mono block power amplifier, drove high sensitivity JBL speakers as well as low efficiency DYNAUDIO speakers with ease and noticeable authority. The sound of violins was audible bright and the vocals were full of emotions. The dynamics and performance in the high frequency spectrum has been the best one that I have ever heard in this sound testing room.
From its pricing, Mingda MC300-PRE with the soft and smooth sound as we would expect from a 300B design, combined with extensiveness in its high and low frequency is most probably the best in his design and price class on the current market.
The circuitry of this preamp suggest that MC300-PRE follows a design philosophy best described as "Simplicity is beauty".
It is estimated that the MC300-PRE is difficult to beat in its sound to cost ratio.
a)The machine adopts pure Class A to amplify circuit ,and tube 300B drives 805 which makes it more perfect.
b)High frequency feels round and bright,while intermediate frequency is full.The low frequency feels strong and the voice field seems wide.
c)It looks powerful with an obvious gradation.
d)A remote controlled volume system is added to the machine,as well as the ALPS Potentiometer from Japan,and the the cover of handle is made by aluminum alloy.
e)The updated products is a symbol that Meixing Factory is coming to a new level.MC-2A3 is produced meticulously,using the Fanuc CNC and lathe bought from Japan at the end of 2010.The entire case is made with a 6mm thick aluminum alloy and the machine feet consists of aluminum alloy as well as the shockproof rubber ring.The factory chooses the chief electronic script.For example,the electronic tube adopts the international brand called JJ in Czech and the 300B from Tianjin.The tube 805 is made by Meixing Factory and the annealed silicon steel imported as well as anaerobic copper wire against high temperature from Janpan.The other materials included in this product is as follows:Jensen copper oil capacitors from Denmark,imported slivering signal line,imported connector,ALPS Potentiometer from Japan,imported aluminum electrolytic capacitor of high pressure,remote controlled handle made by aluminum,imported protective cover of Acrylic and the machine is produced by hand-welded.
f)The effect of the tone quality is comprehensive,correct,vivid and natural.It is worth having one.By the way,it sets up an transform switch called tube 300B/2A3.
