Class A Hi-End Power AmplifierPASS ALEPH-5

Product Description:

This product is made by reference to the famous American circuit PASS Aleph-d core circuit. The original machine cost as much as $20,000.

Every time at a large-scale audio equipment exhibition, the audio equipment of the well-known manufacturer Pass series makes the blood of music lovers boil! But the high price prevents most ardent fans from realizing and owning it.

I'm also a fan of the Pass series. Made a lot of large-scale fever pure Class A power amplifiers for enthusiasts. The creation and persistence of our team on the Pass amplifier. Well received by fans!

Pass is undoubtedly one of the high-end transistor HIFI amplifiers in the world, and Nelson Pass is undoubtedly one of the designers of the ultimate transistor amplifier circuit in the world. He designed the PASS series of circuits that have always been a favorite among music fanatics. One of the most imitated power amplifier lines on the market, the reason is very simple, the line is simple and the sound quality is good! However, imitators are often unable to achieve

excellent sound quality due to various factors such as the layout of the PCB board, the direction of the circuit, the matching accuracy of the power tube, and the matching of materials and tuning!

To this end, we have launched this low-cost, high-performance single-ended pure Class A power amplifier. The materials used are strict, the price is low, and the design and deployment are reasonable. The price is less than one-tenth of the original machine, and you can also enjoy the mellow and beautiful sound quality of PASS A5 single-ended pure A-level!

Using a large all-aluminum chassis similar to the PASS style, the two-channel mirror design makes the wiring more reasonable! The resistors used on the PCB are military 718 original resistors, imported high-power non-inductive resistors. The electrolytic capacitor adopts Nikon, electrodeless electrolysis, the sound is transparent and clear, the sound bottom is clean and neat, the level is good, the low frequency dives well, and the high frequency has penetrating power. The power amplifier tube adopts the new IRFP250 high-power field effect tube of the American IRF company. Each channel adopts 6 pairs of 1% precision matching tubes, and the quiescent current of each channel reaches 2A! Each channel is powered by an independent power module, which consists of 12 Novartis 10000U/50V electrolytes and imported CRC filter non-inductive resistors. The power supply ripple is lower, and the total capacity of the two filter capacitors reaches 240000UF! The transformer is made of two 300W high-quality toroidal transformers A-grade silicon steel wound without a breaking point transformer! (Copper wire transformer), so that the signal-to-noise ratio of the whole machine is extremely high! The AC winding of each channel is independently powered, providing a strong power reserve for the rear stage. This machine is equipped with balanced input interface and unbalanced input interface, which is convenient to connect equipment with balanced interface. The whole machine is equipped with a high-power soft-start circuit and a horn protection circuit to ensure the safety of the transformer and the horn. True mono independent channel, each channel adopts independent rectification, independent protection device, independent transformer, and each transformer is shielded to isolate magnetic interference.

The sound characteristics of this machine: beautiful high frequency, thick and sweet intermediate frequency, elastic low frequency, strong driving force, super good control! Long-term listening will not feel noisy, there is a tendency to want to listen, absolutely super resistant to listening! The signal-to-noise ratio is so high that you can't hear the hum even with your ears close to the speakers. The temperature of this machine is high, please pay attention to ventilation and heat dissipation.
