Introduction:

B24 is a fully balanced pure Class A power amplifier that only has XLR balanced input, which proves that it is not a regular power amplifier. If you use it, you must have a very good fully balanced preamplifier to match it.

As early as 5 years ago, we had already produced B24 PCBs, but due to market changes, it was very difficult to find small signal tubes for B24 matching. Therefore, we began to give up production of B24. After 2 years of slow journey, we continuously searched for B24 matching tubes, but there was no result, but we never gave up searching and ultimately did not disappoint us, We had a chance to meet a friend from Malaysia at an international sound exhibition, and because of him, we were given the high-quality paired signal tube J74/K170, which is a very rare friend. This greatly increases our hope of building B24.

And producing B24 is also very difficult, it is not only assembly, but also debugging. This greatly increases the difficulty of our technicians. So, few people have successfully assembled B24. But we succeeded. This version is already the result of our three-year effort. In fact, for the past 3 years, we have always had a special fondness for B24, and its charm cannot be ignored. After you hear it, you will understand how great it is!!!!

B24 has also appeared in more forums, and more HIFI players want to play it. However, due to the high production level requirements of B24, many people have given up on making it. The completed machine power supply is very heavy, and we used an auxiliary constant current linear power supply as the stabilizing system. On the main power supply, we also used a BC 10000uF/50V x6PCS large filter capacitor to eliminate noise. BC capacitors have always been recognized as capacitors in the HIFI industry, and their sound is not picky. It also has SPK protection to protect your expensive speakers. All resistors use military grade 718 resistors with 5% high accuracy.

On the amplifier motherboard, we also used 16 original NIPPON CHEMI-CON 2200uF/100V high-voltage main filter capacitors. Low frequency can be said to be very good. Control is even less critical. The overall sound direction is very obvious, and the wide sound field is like taking you into a cinema. The details are incomparable to those of pseudo balanced Class A power amplifiers. As a fully balanced benchmark amplifier, B24 greatly demonstrates its strengths at the music level. Its price is also very high in all international market stores. Friends who have learned about B24 should know that in the international market, PCBs alone have already been sold for $300, and even more expensive prices have reached $500 Facts can prove the influence of B24 in the HIFI community.

Adopting high-power 500W OFC pure copper transformer with iron shield to prevent signal interference. The entire internal wiring is very neat and well-designed. The quality of an amplifier depends first on the layout, which is very important. Not only can noise be better eliminated, but also more reasonable wiring can be obtained. Use shielded signal wires imported from Japan, and use high current pure copper wires for output. Crystal gold-plated pure copper terminal. Gold plated XLR input socket. Full aluminum chassis+machine feet.

Please close your iron eyes and slowly enjoy the rhythm brought by B24. The gentle breeze is like blowing in your ear, and the beautiful high pitched voice is just right without any noise. The bass is even more irresistible. Both diving and retracting speeds can achieve good linear effects. Strong and powerful force. If you have a very good HIFI system, B24 will definitely not disappoint you.
